TechTip of the week - Solving the Error Event Problem

If you restart your Windows XP computer several times, you may find an error event added to the System log that says the System Restore filter encountered the unexpected error '0xC0000035'.

This happens because System Restore can't successfully rename the Change.log file. You can work around the problem by turning System Restore off and then back on, but you'll lose your existing restore points if you do this. For more information, see KB article 903264 here.
