I've upgraded to Windows 2000 Server with Service Pack 1 (SP1) slipstreamed. Why doesn't the registry show that SP1 is installed?

A. Slipstreaming, which lets you integrate a service pack's content into a setup area for the OS, is a great addition to Win2K. However, a known problem exists: the system doesn't update the registry key that indicates that SP1 is installed. This is a minor issue, and you can resolve it by performing the following steps:

1. Start regedit.exe.
2. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion.
3. From the Edit menu, select New, String value.
4. Enter a name of CSDVersion, and press Enter.
5. Double-click the value, and set it to Service Pack 1. Click OK.
6. Close regedit.

You can also run servicepack1.reg.
