Change the letter of the drive on all Windows

How to change the drive?

Sometimes the CDROM drive or a hard drive, has a letter that we do not like, such that the DVD drive is the letter "H" when wish it was in the "D:" drive.
Sometimes occurs when you install Windows on a new computer and end of the process we discovered that have changed the drive letters (hard disk or other media). Well here we will resolve all problems.

Please be advised that changing the System Registry is very delicate, follow the instructions at the bottom of the letter, since any change could damage your operating system. Modify the system registry at your own risk.

To change the lyrics of any storage unit, follow the steps below.

1. It would be wise to do a full backup of your computer (optional but recommended).
2. Now start Windows as an administrator (if the user does not have administrator permissions).
3. Click on "Start" button and where it says "Run", type "regedt32.exe" (without the quotes). If the error message appears saying it does not exist, type "regedit.exe". The error is normal in all Windows other than Windows NT, in all modern Windows, always "regedit.exe".
4. In the "tree" that appears, locate the branch called "HKEY_LOCAL_MACHINE \ SYSTEM \".
5. Now a click with the left mouse button on "MountedDevices".
6. With the right mouse button (not the left as before) please click again on "MountedDevices".
7. In the popup menu that appears, click (with left button) in the "Permissions" option (also called "Security").
8. Where it says "user and group name" then a click (left mouse button) on "Administrators" and make sure that the box below, which has enabled all permissions. Finally click the "OK" button.
9. If you have Windows XP, Windows Vista, Windows 7, etc, go to step 10. If you use a dinosaur called Windows NT, close the program, click the Start button and check the "Run" type "regedit.exe "and run. Finally look for the registry key "HKEY_LOCAL_MACHINE \ SYSTEM \ MountedDevices".
10. Now we are back in the branch called "MountedDevices" (from "HKEY_LOCAL_MACHINE \ SYSTEM") and on the right you have to find the lyrics you want to change. In our case we want to change the DVD drive, we currently have on the letter " H, "and we want the" D: ". Therefore we have to look where it says" \ DosDevices \ H: "
11. We changed the name "\ DosDevices \ H:" another not to use, eg "\ DosDevices \ Z:". If you can not change try clicking on "\ DosDevices \ H:" (or whatever) with the right mouse button, and click the "Rename" or "Rename" (or similar) option.
12. If we have the D: busy, skip to step 13. If we have any storage device in the "D:" drive, then simply rename "\ DosDevices \ D:" a drive letter not we use, for example "\ DosDevices \ J".
13. Finally we renamed "\ DosDevices \ Z:" with "\ DosDevices \ D:".
14. Now close the program Regedit and reboot.

How to change the drive system?

If the letter you want to change is a hard disk where you have installed Windows, you must perform the same steps as in the previous section, but there will be a problem when starting Windows.
When starting the drawings appear to choose the user, but if you click on the user (or insert it manually), Windows will not boot and redisplay again to choose user dialogue.

• This is because Windows can not find the "pagefile" according to reports from the official website of Microsoft .
• Another problem also arises, programs do not work because they seek your files on the old disk drive.

Even as Microsoft can not change, the solution is actually quite simple (tested personally):

• Perform the steps in the previous section called "How to change the drive?", As if a drive either.
• Restart the PC with the boot disk Windows installation. boot from the Windows CD-ROM, and start the installation.
• Follow the steps as if it were to install all over again, but just at the moment when the options "Install New Windows" and "Windows Repair", you have to choose the latter option, ie "Windows Repair appear (press C) key "or similar message
• Windows files on the hard disk and most importantly now be copied, correct all routes of Windows that pointed to the old letter.

And that's it.
Just in case I repeat, I am not responsible for the usefulness of these tips, I personally go well but each computer is different and has its peculiarities.
If you know exactly what you are doing, better leave your computer in the hands of professionals
