[EN] How to restore the system/boot drive letter in Windows

Warning Do not use the procedure that is described in this article to change a drive on a computer where the drive letter has not changed. If you do so, you may not be able to start your operating system. Follow the procedure that is described in this article only to recover from a drive letter change, not to change an existing computer drive to something else. Back up your registry keys before you make this change.

This article describes how to change the system or boot drive letter in Windows. For the most part, this is not recommended, especially if the drive letter is the same as when Windows was installed. The only time that you may want to do this is when the drive letters get changed without any user intervention. This may happen when you break a mirror volume or there is a drive configuration change. This should be a rare occurrence and you should change the drive letters back to match the initial installation.

You need to download the tool psexec first.
Suppose that the folder to force delete is c:\<folder>, First, you will need to take ownership of the folder of file to force delete.  In a cmd Command Prompt running as administrator, enter the following command:
takeown /F C:\<folder>\* /R /A
Next, in the command prompt, type
psexec /s /i cmd

Exit the command prompt running as the System account by typing exit.
