The much longer alternative--a solution for all file types--is to edit the Registry.

Note: As always, back up your Registry files--System.dat and User.dat, hidden files in your Windows folder--before proceeding.

Open the Registry Editor by selecting Start, Run, typing

regedit and clicking OK.

Then, navigate your way to HKEY_CLASSES_ROOT\ , where is the type of file you want to preview, such as .gif.

With that key selected, press the asterisk key (*) on your numeric keypad to expand all keys within it.

In order for preview mode to work for that file type, the following entries need to be there:

Registry Key: [HKEY_CLASSES_ROOT\\ShellEx]

Registry Key: [HKEY_CLASSES_ROOT\ type>\ShellEx\{BB2E617C-0920-11d1-9A0B-00C04FC2D6C1}] Value: (Default)="{7376D660-C583-11d0-A3A5-00C04FD706EC}"

If any or all of these entries aren't there, you'll need to create them, as follows:

Right-click HKEY_CLASSES_ROOT\, select New, Key, type ShellEx and press Enter.

Right-click the new ShellEx key, select New, Key, type

{BB2E617C-0920-11d1-9A0B-00C04FC2D6C1}

press Enter. With the newly created key selected, right-click (Default) in the right pane and select Modify.

On the Value Data line of the Edit String dialog box, type {7376D660-C583-11d0-A3A5-00C04FD706EC}
click OK.

run RegEdit and open the following Registry key:

HKEY_CURRENT_USER\Software\Microsoft\ Windows\CurrentVersion\Policies\Explorer

If you see a NoDrives entry, you should see either 00 00 00 00 or 0x00000000 (0) in its Data column, indicating no drives are disabled.
If a nonzero value appears, double-click the NoDrives entry and change the values to all zeros.
A disabled drive may cause odd side-effects, such as grayed-out Open and Explore options on the Start button's Context menu, so make sure all drives are enabled, even if you don't have a drive B:, for example.
