Why Does Microsoft Security Essentials seem to Interfere with System Restore?


Hi, Leo. I have 2 computers with the same problem: one is Windows XP Pro and the other is Windows XP Home. On both computers, System Restore fails as soon as there is a Microsoft Security Essentials restore point entry in System Restore. If I remove all restore points, System Restore works fine. I’ve tested it many times. As soon as MSE creates and updates a restore point, System Restore fails to restore again. Any ideas?

In my experience answering questions here on Ask Leo! since the day System Restore was introduced, it’s been a source of many problems. You can think of these problems as hidden land mines. System Restore may appear to work. It may do something in the background, or it may silently fail. And you don’t really know until you need or want a restore point. Basically, as in your case, it just doesn’t seem to work when people expect it to.

There’s also a common problem of people thinking of it as a backup, which of course it’s not at all.

Why I Don’t Like System Restore


When I go into the System Restore application, it doesn’t give me the option to create a restore point; it only allows me to restore to an earlier point and it never creates restore points. Any ideas on what might be wrong or how to fix it?

I’ll be honest and tell you right off that I have no answer for your question.

There are many possibilities, the most likely being that there is not enough room allocated for restore points. But in my experience, increasing that may or may not resolve the issue.

System Restore is so difficult to diagnose and I hear of so many problems and misunderstandings with it that I avoid it completely.

I turn it off. Completely. It’s not worth it to me.

I’ll tell you what I do instead.
