When I installed my Windows 10 (Free Version) several months ago, I noticed that the old familiar System Restore was missing. After doing some research I found out how to "activate" system restore. I pit it on my desktop for easy access. Today (3-20-17) I found and put on my desktop How to create a Restore Point manually. When I opened it a few minutes ago, I discovered that somehow, System Restore was now turned off, and 0 space allocated. I turned it back on and allocated space. My question is What would cause it to turn off and go back to 0 space? And is there a way to stop it from happening again? My net provider is Frontier Secure, and they have a top notch virus and security check. My thought is some virus slipped by and is hiding in System Restore, and I don't know how to check for that. Has anybody else had problems with System Restore shutting itself off?
