Delete all but the last restore point of the system The good thing is that you can easily delete system recovery points if necessary to recover lost disk space. If you make good use of the system’s recovery function under Windows, you will find that all recovery points take up a lot of disk space on your hard disk. In addition to changing the System Protection disk usage limit to reduce the amount allocated and free up disk space, you can immediately delete and recover almost all of the disk space used by System Restore and hidden copies (including previous versions) by using the Disk Cleanup Manager to eliminate everything but the last system recovery point. Windows system protection can take up to 10% or more disk space to back up system restore points and older versions.
