Noticed how Windows XP "forgets" to keep the Start menu in order?

To fix this, click Start > All Programs, then right-click and choose "Sort by Name" one last time. Then open Registry Editor and browse to HKEY_CURRENT_USER\Software\Microsoft\Windows\ CurrentVersion\Explorer\MenuOrder.

With MenuOrder selected, choose Edit > Permissions. Click the Advanced button and remove the tick next to "Inherit from parent the permission entries…". When prompted click Copy > OK, to close the Advanced Security Settings window.

Now select your username from the list and untick the "Allow" box next to Full Control (leave "Read" ticked) and click Apply. Select the Administrators group and repeat the steps. Finally, click OK and close the Registry Editor.
