Registry Trick: Disable show hidden and system folders in windows

Due to the recent attack of W32.Downadup on our network, I discovered a trick that these types of worm/virus do to hide themselves being seen even by checking the show hidden files and folders in Windows Explorer > Foder Options. I realized that this trick can also be use for a good purpose such as strengthen application security. A good example is hiding a flat database file from end-users.


The Trick:

1. Open your regedit.exe
2. Go to HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows > CurrentVersion > Explorer > Advanced > Folder > Hidden > SHOWALL
3. Change the value of CheckedValue to 0 (zero).

And there it is. Good Luck!
