After installing ATI 11, I've noticed that my Windows Update installs now fail. The only error mentioned is "Code 8020000D", from Windows Update. Web searches seem to indicate that this has something to do with volume locking. Does anyone have any idea how to fix this ? The only workaround I've found is to run the Windows Update shortly after a fresh reboot. I have daily ATI backups scheduled, and I'm not sure, but I think the Windows Update failures occur after the system has been up past a backup run.
