For six months I have been running ESS7, ESS8 beta and ESS 8 on three different Windows 8.1 X64 machines. During that period I have several occasions to use system restore on those machines. In each instance system restore would appear to run successfully but after rebooting and running, an error message appeared indicating that system restore failed because it could not read a file. The message would indicate that the likely cause was the file was blocked by the antivirus installed. The message said to stop the antivirus and retry system restore.
I would stop ESS and rerun system restore. The result each time was system restore would fail again with the same messages appearing.
After seeing these failures, I would uninstall ESS, retry system restore and it would run successfully.
It appears that all three of the above listed ESS versions do something that blocks system restore from running.
I have presently uninstalled ESS from all machines and reverted to Windows Defender. There are now no system restore issues.
Anyone else seen this conflict between ESS and system restore on Windows 8.1 64bit?
