This utility uses to create a data store. If you don't have 200MB of free space, System Restore remains disabled until the space becomes available, at which point the utility enables itself. System Restore uses a first in/first out (FIFO) storage scheme: The utility purges old archives to make room for new ones when the data store reaches a set limit.
The file types that System Restore monitors are many but include most of the extensions that you typically see when you install new software (e.g., .cat, .com, .dll, .exe, .inf, .ini, .msi, .ole, .sys). Note that only application installations that use a System Restore restorept.api-compliant installer will trigger the creation of a restore point.

Problems with System Restore:
There are few problems associated with System Restore when it comes to viruses.When restore points are created they are stored in a directory that is accessible only to the System account and not to a user. This keeps the restore points safe from misuse and tampering.
Unfortunately this also means that any virus scan software you may have installed can not scan the files located there as well. This causes a problem if a file that is infected with a virus gets backed up into a restore point because now the anti-virus software can not clean it.
Now if you ever restore from a restore point, that file that is infected will be introduced back into your system.
Keeping this in mind, if you find that you are infected with a virus, hijacker, or spyware and want to make sure you do not get reinfected. You Should Turn System Restore Off And Then Back On Again To Clear All The Restore Points. This will guarantee that their are no infected files that could be restored.
