LetterSwap allows you to swap drive letters and/or synchronize letters of disks on based on the registry of the guest OS.
This is useful for mounting a boot drive in WinPE eg. Y:
The utility forcefully changes drive letters even if they are already used (letters abxyz are ignored), therefore it is desirable to launch letterSwap as soon as possible, for example through RunOnceEx.
This is a fork of the open source LetterSwap written by Nikzzzz and released on TheOven.org.
