Slow Shutdown

Some people have noticed that they are experiencing a really slow shutdown after installing Windows XP Home or Professional. Although this can be caused a number of ways, the most clear cut one so far is happening on systems with an NVidia card installed with the latest set of drivers. A service called NVIDIA Driver Helper Service is loading up on start up and for whatever reason doesn't shut itself down properly. The service isn't needed and can also increase the amount of memory available to your system. Here is how to disable it.

1: Go into your Control Panel
2: Select Administrative Tools and then click on Services
3: Right click on the file "NVIDIA Driver Helper Service" and then select STOP.
4: To stop this loading up every time you boot up your PC Right click it again and select properties - then where the option "Startup Type" is shown - make sure it is set at Manual like we have shown in the image below.

Restricting Logon Access

If you work in a multiuser computing environment, and you have full (administrator level) access to your computer, you might want to restrict unauthorized access to your "sensitive" files under Windows 95/98.
One way is to disable the Cancel button in the Logon dialog box.
Just run Regedit and go to:

HKEY_LOCAL_MACHINE/Network/Logon

Create the "Logon" subkey if it is not present on your machine: highlight the Network key -> right-click in the left hand Regedit pane -> select New -> Key -> name it "Logon" (no quotes) -> press Enter. Then add/modify a DWORD value and call it "MustBeValidated" (don't type the quotes). Double-click it, check the Decimal box and type 1 for value.
Now click the Start button -> Shut Down (Log off UserName) -> Log on as a different user, and you'll notice that the Logon Cancel button has been disabled.
