hmmm maybe 'system32/dllcache' confuses some1...

i wanna remove 'dllcache' folder located at 'system32' folder

Well, dllcache is the directory where Windows saves backups of all the current critical OS files for use with Windows File Protection. I doubt you'll actually be able to delete it even if you wanted to, but even if you could, it's probably not a great idea.

Of course, that's why we have VirtualPC Give it a shot and let us know what happens

I would keep that folder. Why would you want to remove it anyways?

The directory, no, but all the files, absolutely. I have been doing it for a while. You can also take a look into the event viewer after you install an application, and if there was a protected file overwrite, it will tell you in the viewer which file had been replaced. You will also be prompted to insert the CD whenever this happens, but you can choose cancel (or was it ignore ...). With the hacked SFC_OS.dll you should be able to control the warning / ignore behaviour for these message boxes.
