XP's cannot enable show hidden file option

[willy]

Problem: Unable to use set the option "enable show hidden file" in XP's explorer.

Solution:

Go to the following registry key:

HKLM\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL

Delete the value CheckedValue. (Its type should be REG_SZ and data should be 2.)

Create a new DWORD value called CheckedValue (same as above, except that the type is REG_DWORD). Modify the value data to 1 (0x00000001).
