Windows 10: How to change SYSTEM drive letter from C to any other letter (A or Z)

Hello!

I have a dark desire and some OCD related spasms to make some changes on how Windows10 is arranging the drive letters in explorer.exe, i would really appreciate any guide, advice or joke on this.

Short story
I want to change the default system partition letter from C to A or Z -> is there any way to do it (even if its risky)?

Long story
I have 6 internal drives and 2 external drives on my computer at all time with a few partitions on each of them and some other devices, something like this:

Drive1 is an SSD-240GB
with only one partition [C] where Windows10 is installed and other 2 hidden partitions (Recovery 500MB, and EFI 100MB)
Drive2 is an SSD-1TB
with two partitions on it [D] for backup and [E] for installed programs and games
Drive3 has two paritions [F], [G]
Drive4 has three partitions [H], , [J]
Drive5 has three paritions [K], [L], [M]
Drive6 has three partitons [N], [O], [P]

extDrive1 has two partitions [Q] and [R]
extDrive2 has two partitions and [T]

I use partitions and [V] and [W] for virtual images (PowerIso), partitions [X] and [Y] for usb sticks and [Z] for an external DVD-RW

What i want to do is to change the system drive letter from [C] to [A] or [Z] - as i want the system to be at the begining of the alphabet or at the end (it`s so annoying that the system is the third letter of the alphabet that every time i open explorer i have to loudly pronounce the whole alphabet from A to Z three times just to calm down - (sometimes i use the numbers and special characters to)...

Is there any way to do it ? (as searching for this information on ggl only led me to solutions to another problem)

I know letters A and B were used for floppy disk and they were there to let you boot into earlier versions of win (98 and below) ... this days most of the MotherBoards don`t even have pins for a floppy disk (there are some usb adaptors - but then it reads the floppy as a removable drive and it assigns the next letter available), and i think Microsoft should change the drive letter for the system files - but this is another discussion for a later post.

Thank you for your patience to read this and thank you in advance for any answer!

Changing the system volume drive letter safe?

Ever since I reformated, my drive letters have changed besides C:\ and I would like to change back the other 2 drive letters.(One being the system volume letter) just so the programs I use to have still work. Is this safe? What are some negatives?

 

Changing the system volume drive letter safe?

It depends. Need some more information. Is your boot volume c: ? If so, then others can be changed around as needed, but there may be collateral damage. Usually, if there are pointers set in the registry, as long as you use the storage management plugin to change the drive letter assignments, most things should work.

Trouble comes in the form of applications that keep file system information (folders, path names, etc) in files that are stored in directories during installation. Those usually cannot be changed easily, unless you know that they are there and where they are....

What drive letters are you trying to change specifically, and what is the operating system

 

Reformatting - Wrong Drive Letters?

Ok, do so googling about acronis True Image 11 and disk letters. Its the program I use to save all my info, and I know that people wee having troubles with the drive letters there. It was something about modifying the boot.ini and assigning drives. Anyway, I found this for you:

Change the System/Boot Drive Letter
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

1. Make a full system backup of the computer and system state.
2. Log on as an Administrator.
3. Start Regedt32.exe.
4. Go to the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices
5. Click MountedDevices.
6. On the Security menu, click Permissions.
7. Verify that Administrators have full control. Change this back when you are finished with these steps.
8. Quit Regedt32.exe, and then start Regedit.exe.
9. Locate the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices
10. Find the drive letter you want to change to (new). Look for "\DosDevices\C:".
11. Right-click \DosDevices\C:, and then click Rename.

Note You must use Regedit instead of Regedt32 to rename this registry key.
12. Rename it to an unused drive letter "\DosDevices\Z:".

This frees up drive letter C.
13. Find the drive letter you want changed. Look for "\DosDevices\D:".
14. Right-click \DosDevices\D:, and then click Rename.
15. Rename it to the appropriate (new) drive letter "\DosDevices\C:".
16. Click the value for \DosDevices\Z:, click Rename, and then name it back to "\DosDevices\D:".
17. Quit Regedit, and then start Regedt32.
18. Change the permissions back to the previous setting for Administrators (this should probably be Read Only).
19. Restart the computer.
