If your Windows computer is experiencing problems, such as low performance and lack of disk space, you can use System Restore to restore system files, program files and registry information to their previous state.

Details: The system restore program failed to retrieve the file (C: \ Windows \ Installer) from the restore point. An unknown error occurred during system restore (0x80070301). “

Why should this happen? Actually, there can be two reasons for the above error. On the one hand, you may have a security program and antivirus program installed on your computer. The other reason is that if there is a file conflict during the recovery process, some specific files will not be replaced properly. There could be many other reasons for this. However, finding the right solution is the most important thing you need to do right now.
