How to disable the recent document history on your computer...???

Hi everyone here is new tricks I’m going to
show you how to disable the recent document
history on your computer. This is a great thing if
you don’t show your recent document history.
The bad thing about Recent Documents History
is that Windows XP has to calculate what should
be put there each time you boot Windows, which
can slow things down.
1. At first open the Registry Editor by pressing
“windows + R” then type “regedit” and then hit
enter. (Select Start/Run, type regedit, and click
OK).
2. Now go to “HKEY_CURRENT_USER\Software
\Microsoft\Windows\CurrentVersion\Policies
\Explorer”.
3. And then Create a NoRecentDocsHistory
D_WORD key [Right Click® New ®DWORD (32-
Bit) Value] . Double-click the value to open it
once it is created.
4. Set the Data Value to 1 to enable the
restriction with hexadecimal.
5. Click OK and close the Registry Editor. You'll
need to restart the computer for the change to
take effect.
Note: If you want to enable recent document
then go to “HKEY_CURRENT_USER\Software
\Microsoft\Windows\CurrentVersion\Policies
\Explorer”. and delete “NoRecentDocsHistory”
file that you have create and restart your
computer.
