How to change system drive letter in Windows 8 RTM?

I've installed Windows 8 starting the installer from Win8 RP and I've just noticed that it picked up the drive letters from the old system. Now my system drive is Y instead of C , because in the old system that partition was Y.
If I try to change the drive letter in the Drive Management it gives an error.
Does anyone know how to change system drive letter in Windows 8 RTM?

This can definitely be a pain. I believe this article may help:

Thx! I saw this already, but there is no Regedt32.exe in Windows 8 OR I can not find it.

Yes there is. you have to go to the command line. Both Regedt32 and Regedit work. You also have to run the command prompt as administrator.

Or you can just start typing "regedit" on the Metro screen and launch it from there, you can right click on it and run as administrator also.

Press Windows Key + R and put Regedt32.exe

Click Yes for UAC permissions.

Ok I found the regedt32.exe The problem was that I was looking for "rededit32.exe" .
I made the changes suggested by the article, but after restart the system hangs at the login screen.
I had to make a system restore to start it again. :/
