if it locks on desktop, cntrl alt del and see if explorer.exe is showing in the background. if you can cntrl alt del, then choose new task/run and then type cmd and press enter. should get to a dos shell. now goto the system root folder (probably c:\winnt) if u are there then type this in:
ren browseui.dll browseui.old <enter>
now reboot. if you dont know dos commands then just remember
cd.. goes back a directory, cd <folder name> goes into that directory and DIR/p lists directory stuff. so, say you are in c:\> you would type the following:
c:\>cd winnt <enter>
dont type c:\>, just type cd winnt.
this can be reversed, by the way. all you would need to do is go back into prompt and type
ren browseui.old browseui.dll <enter>
