Hi, I am using Windows 7 64-bit and wanted to know: Will ERUNT damage security patches etc, that are downloaded with Windows Updates? Let me explain with a fictitious scenario: I create an ERUNT back-up on Monday, on Wednesday, Windows searches, downloads and applies some new patches, then on Friday I restore the original ERUNT back-up registry I made on Monday. I assume that when security patches etc are installed via Windows Updates it installs new non-registry files into some folder somewhere, as well as new registry entries as well. Now, these registry entries will obviously be overwritten when I restore the ERUNT back up I made and I am wondering whether this would compromise the patches. If an earlier Acronis or Windows Image is used, obviously Windows will search for all the updates that haven't been installed since the Image was made, but in the case of ERUNT because it doesn't touch the non-registry files (some of which tell Windows that they are installed) what I'm concerned about is that Windows will think that they are installed but as they are missing bits from the registry they might be flawed security patches. Is this how it works, or would Windows know that they need to be re-downloaded? Sorry if I have confused anyone!
