Windows 10: Lower free space on C drive after failed system restore

After installing a software 'Simatic net', I tried to restore C drive to get back to before installation point. But I see this Error at the end of operation An unspecified error occurred during system restore 0x800705aa . and then I understand that my C drive has lower space. Before I did system restore, C drive free space was 24 GB but now is 18GB.I just want to delete these new files that is created by failed operation and do not want to undo that system restore. Any advice?!

c drive space decrease

Hello,

This behavior can occur when System Restore is turned on on your computer. System Restore uses a portion of the hard disk to store "restore points." These restore points are used by System Restore to return your computer to an earlier state.

System Restore creates a new restore point each time that you start the computer.

Free hard disk space reduce after system restore

I have problem getting update for windows. So decided to do a system restore. After doing a system restore i am able to update my windows but notice the free hard disk space had reduce.
Before doing the system restore my free space in my C drive is about 33.6GB ( if i am not mistaken, quite sure anyway ) but after the system restore is 26.6GB. Despite having less program installed.
Any idea where to those free space in my C drive went? And any idea what went wrong?

 

Free hard disk space reduce after system restore

If your system is running ok now, you could disable system restore then re enable it, thus removing all previous restore points and freeing up that lost space!
