JSI Tip 10317. When you attempt to update Windows XP to SP2 (Service Pack 2) from Windows Update, you receive 'Unable to read from or write to database'?

To workaround the subject behavior:

1. Open a CMD.EXE window.

2. Type the following commands, pressing Enter after each line:

net stop cryptsvc
del /q %systemroot%\system32\catroot2\Edb*.log
del /q %systemroot%\security\Edb*.log
net start cryptsvc
4. Visit the Windows Update Web site to update the computer to Windows XP SP2.
