I cant access my regedit or many other programs n my computr i don't know what to do now. Can anyone help me?

I recently edited some stuff in my regedit where i was changing the destination drive (C: to D:) and then i altered a couple of other things. But now i can't access regedit or my dvd drive (F:) to use anything, and a lot of the things that are on the C: drive can't be acessed either. So basically i need to find out how to fix this or gain acees to my regedit? p.s answers without me having to go and buy stuff for it please.I cant access my regedit or many other programs n my computr i don%26039;t know what to do now.

People that don't know what they are doing, should not be renaming drives needlessly!I cant access my regedit or many other programs n my computr i don%26039;t know what to do now. Can anyone help me?
you have a couple options depending on how prepared you were to mess it up you should have backed it up first



try undoing your registry editing.



if nor restore your computer by disk or restore point.



reinstall windows start over.
