Right-click on the file and select Extract All, and save to the default destination (which should be a folder on the desktop)

Create a new System Restore point

Open an Elevated Command Prompt, and run the following commands.

Code:

IF EXIST C:\Windows\System32\config\COMPONENTS.OLD1 DEL C:\Windows\System32\config\COMPONENTS.OLD1
REN C:\Windows\System32\config\COMPONENTS COMPONENTS.OLD1
COPY "%userprofile%\desktop\tbeac\COMPONENTS" C:\Windows\System32\config
 
.

If you get an error with any command, STOP THERE - do not reboot! - post for instructions.

Assuming all commands go OK, reboot, and run another CheckSUR scan - post the new CheckSUR.log file.

That's reduced the errors significantly, at least!
