How to Assign / Change Drive Letter in Windows 10
We show you how to change the drive letter in CMD, DIsk Management, PowerShell, and Registry editor in Windows 10.

Windows 10 helpfully assigns drive letters to disks as they’re added, but they aren’t always the most logical choices. While we all know that C: is the system drive, it doesn’t make quite as much sense to have D: as your games drive or E: as your media drive. Luckily it’s quite easy to change a drive letter in Windows 10, and we’re going to walk you through the process today.
How does Windows 10 drive letter assignment work?
For the most part, Windows 10 automatically assigns letters to drives as they’re connected, in alphabetical order. However, there are a few exceptions to this rule that may leave some users confused.
As mentioned earlier, C: is always reserved for the system drive, but A: and B: are reserved too, for rarely used floppy drives. Because of Windows automatic assignment, you may have also noticed that Windows changes the drive letter of your USB stick if you’ve connected another before it.
If you want letters that are easier to identify in bios or don’t want your USB letters jumping around, it’s quite easy to permanently change a drive letter in Windows 10 to something of your choosing. We’re going to cover a few different ways today, including how to change the drive letter in CMD.
How to Change Drive Letter in Windows 10 via Disk Management
The most user-friendly way to assign drive letters in Windows is through the Disk Management interface, which is relatively easy to use.

How to Change Drive Letter in CMD using a DISKPART Disk Management Command
Though it’s not quite as user-friendly, it can be much faster to change a drive letter with Command Prompt.

How to Change Drive Letter in Windows 10 with a PowerShell Disk Management Command
Those more familiar with PowerShell can use this method instead to achieve the same result.

How to Change / Assign a Drive Letter via the Registry Editor
Alternatively, if none of the above methods worked or you’re just feeling brave, you can modify the drive letter via the registry. Just be sure to read our safe registry editing guide first.

If you enjoyed this guide, you may want to consider enabling or disabling disk caching or turning on BitLocker for your newly customized drives.

Steps to change drive letter assignment in windows.
Windows uses MountMgr to manage drive letters. MountMgr will assign the next available drive letter to each device added, regardless of type. With the system drive assigned the letter C: , there may be other IDE, SATA or USB devices, such as a DVDROM or a Flash drive assigned to letters D: and E: . When adding another drive, Windows 10 / 8 / 7 / Vista and XP will assign the next drive letter available, which in this case would be drive letter F: .
Drive letters can usually be manually changed using Disk Management , however there may be some exceptions. For full details please see the relevant Instructions or Microsoft Knowledge Base article below:

How To Remap Or Reassign Keys On Your Keyboard
Unless you own a high-end keyboard or a custom mechanical keyboard , chances are you might not be able to configure your current keyboard’s layout to your liking. Of course, for the most part, we imagine that many people are already satisfied with the way their keyboard has been laid out.
However, if you think that certain keys would be better placed elsewhere, or if you want to disable certain keys, you can actually do that. Unfortunately, there is no native way to remap or reassign keys in Windows, but our guide below will show you several different apps that might be worth checking out if you want to remap your keyboard or reassign several keys.
SharpKeys ( Download )

Also, another thing to take note is that it will write to your computer’s registry, so if you’re not familiar or comfortable with that, you might want to seek out an alternative.
Keytweak ( Download )

For example, some users might not have a need for a Caps Lock key, so they might want to reassign it to something else, such as Ctrl or Alt.
MapKeyboard ( Download )

The UI will also highlight keys in green to indicate that they have been edited, and once you’re done editing, you’ll need to logoff your computer and relogin and you will be all set and the changes will take effect.

AutoHotKey ( Download )
The software we listed above does a very good job of remapping or reassigning keys. However, if you need something a bit more complex and powerful, that’s where AutoHotKeys comes in handy. This is because with AutoHotKeys, with a little bit of time and learning, you can create scripts to run more complex actions.
For example, you can create macros with AutoHotKeys where with by pressing certain keys or shortcuts, you can type certain lines of text, run programs, batch files, and so on. You can even make shortcuts even shorter, where instead of pressing three keys, you can reduce it to two, and so on.
However, like we said, AutoHotKeys is a bit more complex and you will need to learn how to script it, but it can be a very powerful tool once you get the basics down.

Changing the letter of a drive is easy on Windows 10 and Windows 11, but you should do it as soon as you add the drive to prevent future hassles. Find out how to change a drive letter here.
What Changing a Drive Letter Does How to Change a Drive Letter How to Fix Programs Broken By Changing a Drive Letter Fix The Shortcut Reinstall the Program Change the Drive Letter Back Edit the Registry
What Changing a Drive Letter Does
Windows assigns drive letters alphabetically — starting with C — when they’re initialized. If you want to change a drive letter, you should do it before you install anything on the drive. Changing a drive letter after programs are installed could break them since there will be references to an installation location that is no longer there.
Windows has gotten pretty smart about updating shortcuts so that programs work after changing a drive letter. Most of your applications’ shortcuts will probably be automatically corrected. Unfortunately, Windows isn’t as good about updating file associations. You’ll have to manually set the default apps associated with files to fix file associations if they were broken by changing the drive letter.
Warning: It is possible to change the boot drive letter to something else, but we don’t recommend it. Changing C:\ to another letter is likely to result in severe issues, like a PC that cannot boot into Windows at all. Even if it were able to boot, there would be a huge number of programs that would not be able to run.
Note: Technically speaking, while they are commonly called drive letters, each letter actually refers to a partition on a disk. If you have multiple partitions on a single disk, you will need to assign a letter to each partition to make them all accessible. If a disk has just a single partition, it will just have a single letter pointing to that partition. (However, you do not have to assign a letter to each partition. Partitions without drive letters will not appear in File Explorer and elsewhere.)
How to Change a Drive Letter
Changing a drive letter is pretty simple. Click the Start button, type “Disk Management” in the search bar, and then hit Enter.
Note: The program name displayed in the search will not be Disk Management. It will be “Create and format hard disk partitions.”
You could also hit Windows+X or right-click the Start button, and then click “Disk Management.”
Identify the drive you’d like to change in the Disk Management Window. In this example, we’ll change the letter of the D:\ drive to J:\. You can right-click the drive on the text list, or on the menu below. Either works.
Select “Change Drive Letter and Paths” in the right-click menu that appears.
In the window that pops up, click “Change.”
Select whatever letter you want from the drop-down menu. Then click “Ok.”
Two popups will warn you about changing your drive letter. Click “Yes” on both of them, and then restart your computer.
Once Windows has restarted, the drive letter should be changed.
How to Fix Programs Broken By Changing a Drive Letter
There are a few ways you can fix a program broken by changing the drive letter.
Fix The Shortcut
If you’re lucky, the only thing that is broken is the shortcut. Fix a shortcut by right-clicking the shortcut on your desktop, and then click Properties.
You need to change the target of the shortcut to the new drive letter.
For example, if GIMP was previously installed at “ D :\GIMP 2\bin\gimp-2.10.exe,” and you changed the D drive to J, change the target of the shortcut to “ J :\GIMP 2\bin\gimp-2.10.exe.”
Finalize the change by clicking “Apply” and then “Ok.”
Reinstall the Program
Reinstalling the program will generate new entries in the registry, so everything on the computer will know where to look for the program. Some installers won’t like reinstalling directly over existing files, so you may need to rename or delete the old installation first.
Change the Drive Letter Back
If you changed the drive letter of a drive with a lot of programs installed, it might be easier to change the drive letter back. Changing the drive letter back should automatically fix any programs and file associations that were broken.
Edit the Registry
Warning: You can break programs, or even Windows itself, by editing the registry. Be careful, and learn about how to edit the registry before you try it. Make sure you backup the Windows registry first. You should not attempt this method unless you have no other options.
Windows, and a lot of programs, track where programs are installed via the Windows registry. It is possible to manually adjust the registry to fix broken programs. Keep in mind that there could be dozens of registry entries you need to edit. A program like GIMP can have registry entries for the context menu, for the “Open With” menu, for any file associations, and for the location of its executables. Other programs may only have a few entries related to where it is installed.
If you’re not deterred, here’s how you do it.
First, you need to know where the program was previously installed. In this case, the program was installed to the “D:\GIMP 2” folder, and the executables were found the “D:\GIMP 2\bin” sub-folder. It is now located at “J:\GIMP 2” instead.
We need to update the registry to reflect the change in location. Click the Start button, type “regedit” into the search bar, right-click Regedit, and click “Run as administrator.”
In Regedit, hit Ctrl+F to bring up a search window. Type in the old location for the program you’re trying to fix — “D:\GIMP 2” for our example — then click “Find Next.”
Once Regedit has found something with “D:\GIMP 2” as part of a path, it’ll show it to you. Here is an example from the GIMP search.
To actually change them, double click the name of the registry entry you want to modify. Then change the drive letter to J, or whatever you chose. If you didn’t otherwise move the folder, leave the rest of the path alone. Then click “Ok.”
You’ll need to repeat this multiple times. To find the next result using your search term, you can hit the F3 key. There will be a popup once you’ve found all of the entries.
Changing drive letters can be a simple way to customize your PC. Do it before you install anything on the drive, however. You’ll prevent any problems before they occur, and probably save yourself quite a bit of troubleshooting.

How to Write a Memo That Assigns Additional Duties
by Anam Ahmed
Published on 29 Apr 2019
The business environment is dynamic and constantly changing. Successful companies know how to adapt to the fluctuations in the marketplace by adjusting their offerings to meet the needs of consumers. In order for that to happen, companies need to be able to remain flexible with their internal organizational structure. Sometimes, it’s necessary to change roles and responsibilities within the company in order to complement the external environment.
Review the Current Job Description
If your organization needs to make some changes to an employee’s job responsibilities, you’ll need to provide them with the details in writing. Having a brief discussion with the employee is also useful as it enables them to ask questions and gain clarification. The memo acts as a written confirmation of what is discussed between you and the employee. The additional responsibilities letter format is short and clearly outlines what changes the employee can expect.
Before you draft your memo, review the employee’s current job description so you have a comprehensive understanding of what they do now. You may also want to review their past performance reviews to see what their strengths and weaknesses are. This will help you determine what kinds of changes the employee will be able to handle successfully.
For example, if your employee is a customer service representative, you may wish to increase their role by having them respond to customer inquiries over social media as well. However, if in their past performance reviews they have not had a great track record of written communication, then this may not be the best change in duties for them. However, if they excel in written communication and social media management, they may thrive with the new responsibility.
Make Sure the Changes Are Feasible
Ensure that the changes you want to make to the employee’s job description are realistic . If they already have too many tasks on their plate, then adding even more duties may overwhelm them and cause a loss in productivity. If you’re adding on additional responsibilities, you may also need to remove some other duties.
When learning about additional responsibilities, employees will want to know whether they will be compensated to reflect the changes in their role. A good sample memo for duties and responsibilities outlines if any changes will be made to the employee’s salary as a result of the changes in their job description. Ensure this increase in salary is within the budget.
Structure a Sample Letter of Duties and Responsibilities Carefully
Open your memo by stating the intention for the letter. Tell the employee that you are changing their job description. Also mention why the change is happening as it relates to the business.
In the next paragraph, focus on the employee’s strengths and the value they bring to the organization. Build on that by outlining the additional responsibilities they will be taking over. If you’re removing some of their duties to account for this change, let them know who will be taking over those areas.
Finally, if there will be a change to the employee’s salary as a result of their increasing job description, tell them about the change and from when it will be effective. Sign off by sharing your excitement for what this means for their career and for the organization. Offer to answer any questions and share next steps .
Sample Letter for Change in Job Responsibilities
Subject: Your new role
I’m writing to inform you about a change in your job description at XYZ Corp. In addition to your duties as Customer Service Representative, you will now also be responding to customer questions over our three social media channels. As we grow our business, we’re expanding the way we service our customers. We’ve conducted research with many clients and this is a service they are eager to have.
Since you’ve been with us here, you have excelled in all areas of customer service, particularly in the areas of written communication and timely response. These skills will be critical to your new responsibilities.
To reflect your changing responsibilities within our organization, and to show our appreciation for your work, you will receive a 3 percent raise effective immediately.
We’re thrilled about this new development and look forward to seeing you grow in your expanding role. Feel free to reach out if you have any questions. We’ll schedule a meeting to discuss the next steps moving forward.
Best wishes,
How to assign permanent letters to drives on Windows 10
You can assign drive letters manually, and in this guide, we show you how on Windows 10.

On Windows 10, when connecting a removable storage device or an internal hard drive, the system detects and assigns a drive letter automatically to make it usable. However, when reconnecting an external drive (such as a USB flash drive or SD or microSD cards), the system can end up assigning a different letter, which can be annoying.
If you want to see the same drive letter on a particular device, you can manually assign a permanent letter to any drive connected to your computer, and on Windows 10 , you can do this in at least three different ways, using Disk Management, Command Prompt, or PowerShell.
Using this approach will prevent Windows 10 from assigning a new letter or trying to set a letter already in use, which can cause conflicts. Also, it helps to select a drive letter that makes more sense to you.
In this Windows 10 guide, we walk you through several methods to manually assign a permanent letter to a drive, as long as you're connecting the drive to the same device and the letter isn't already in use.
How to assign a drive letter using Disk Management
How to assign a drive letter using command prompt, how to assign a drive letter using powershell.
To manage drive letters with the Disk Management tool, use these steps:
- Open Start .
- Search for Create and format hard disk partitions and click the top result to open the Disk Management experience.
- Right-click the drive and select the Change Drive Letter and Paths option.
- Click the Change button.
- Select the Assign the following drive letter option.
- Use the drop-down menu to assign a new drive letter. Quick tip: To avoid the system trying to assign the same letter to another drive, it's a good idea to start adding letters in backward order. For instance, instead of using D, E or F, it better to start with Z, Y or X when assigning a new letter.
- Click the OK button.
- Click the OK button again.
Once you complete these steps, the drive will permanently retain the assigned letter, even after reconnecting it. However, if you connect the drive to another device, it may receive a different letter.
While the easiest way to assign a new drive letter is to use Disk Management, you can also use DiskPart in Command Prompt to perform the same task.
To assign a drive letter using Command Prompt, use these steps:
- Search for Command Prompt , right-click the result, and then select the Run as administrator option.
- Type the following command to start DiskPart and press Enter : diskpart
- Type the following command to list all the available volumes and press Enter : list volume
- Type the following command to select the volume (drive) to assign a new letter and press Enter: select volume 3 In the command, make sure to change "3" to the number that represents the drive on your device.
- Type the following command to assign a new drive letter, and press Enter : assign letter=Z The command assigns the letter "Z" to the drive assuming it's available. However, you need to make sure to change the letter for the one that you want to use.
After completing these steps, similar to Disk Management, every time you reconnect the storage to the same device, Windows 10 should assign the same letter automatically.
Alternatively, you can also use PowerShell to change a drive letter on Windows 10 using these steps:
- Search for PowerShell , right-click the result, and then select the Run as administrator option.
- Type the following command to list the available drives and press Enter : Get-Disk
- Type the following command to assign a permanent letter to the drive and press Enter : Get-Partition -DiskNumber 1 | Set-Partition -NewDriveLetter Z In the command, make sure to change "1" to the number that represents the drive that you want to modify, and change "Z" for the new letter that you want to use.
Once you complete the steps, the drive will be accessible through File Explorer using the letter that you assigned, and Windows 10 won't try to change it.
Updated March 7, 2019: We revised this guide to make sure it's current with the latest version of Windows 10.

- Scenario: I have four 16GB USB flash drives that I use for various OS installs. I typically work on one at a time, plugged into the same USB port. Sometimes I connect two at a time. I just accept that Windows will assign the next available letter to the current connected drive. So, if I manually assign a letter to one flash drive, will it get that letter every time, but the other three will not be assigned that letter?
- Yes, that's how it should work.
- Unfortunately this won't work with the same letter assigned to multiple drives. Only the most recent is remembered. They really need to get away from drive letters and switch to using the actual name of the drive.
