Folder Options-Show hidden files and folders not function

Here some fix to restore “Show hidden files and folders” to work as usual,

1. Click “Start” -> “Run…” (or press Windows key + R)

2. Type “regedit” and click “Ok”.

3. Find key HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced)

4. In the right hand area, double click “hidden” and change the value to 1

5. Find key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL

6. In the right hand area, double click “CheckedValue” and change the value to 1.

If it isn’t, create a new key called “CheckedValue” as a DWORD (hexadecimal) with a value of 1.

The “Show hidden files & folders” should now work normally. 🙂

If it doesn’t work, please download new update of your antivirus and scan your system completely.
