Just in case anyone is thrown by the "ERU for Windows NT" or by the install saying it's for "Windows NT/2000/XP", it seems to work fine with Vista Home Premium.

Yes, it hasn't been updated for some time, but ERUNT works just fine with all versions of Windows Vista, and with 64-bit versions of XP and Vista. Updated the first post.

Great Tool. I will be adding to my toolbox!

Just a word of caution to all:

Installing ERUNT also installs NTREGOPT by default. This is a "registry optimization tool" that completely hosed the last computer I tried it on (as a test, luckily).

Registry cleaners are not recommended here at Geeks to Go.

Please do not use NTREGOPT.
