I've been using Eaz-fix now for a couple months and It's great. I got into a situation where comodo turned explorer.exe into an isolate application and it couldn't run other apps which made things very painful. I had made a snapshot before and after installing comodo and I've rolled back and forth with no problem at all. My question is it ok to delete snapshots between the baseline and the snapshot that you are currently using? Is there something that I shouldn't do that will affect eaz-fix? Such as chkdsk or defragging? I know Easter is up on eaz-fix and I would appreciate his opinion. Thanks.
