Just a small reminder. In case you havent, you must uninstall any RC builds (any build less than 6.0.6001.18000) before they expire on June 30.
After this date, the kernel will stop with an END_OF_NT_EVALUATION_PERIOD error message an hour after the machine has booted. If you do wait until after June 30, just reboot your PC and start the uninstall process right away.
How do you know if you’re running a pre-release build?
If your desktop says “For Evaluation Purposes”, you are running time-limited beta/RC software and will need to uninstall. Another check is to hit the start button and type “WinVer” – if it lists an expiration date then you have a time-limited version of SP1.
How do you uninstall pre-release versions of Vista SP1?
If you installed SP1 Beta/RC as an update to an existing RTM version of Vista, you can probably uninstall it directly. For instructions on how to uninstall SP1, please seehttp://support.microsoft.com/kb/948537. The best way is to uninstall from the “Programs and Features” control panel icon, using the “View Installed Updates” option on the left, click Service Pack for Microsoft Windows (KB936330), and then click Uninstall.
