System restore

 

is the utility used 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. This requirement has been raised to 300 MB in Windows 7. You can clean up temp files to free up some amount of space on your Hard drive and interestingly this procedure can be automated at startup.


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.

2. "Welcome" screen appears asking for restoring the system or to create a restore point.
