Hi,
I have just witnessed a fairly hefty bug in the latest Windows repair. I say hefty only because System File Checker is a vital component to Windows (and Tweaking.com All in One Windows Repair as well); However any diligent computer tech will do their own checks to ensure that the error isn't just a type 1 error....put simply rather than accepting that the error "Windows Resource Protection could not start the repair service" as being true, I decided to dig a little deeper.
1). the Trusted Installer Service is in fact running
2). Windows modules service is also running
3). Running the command manually directly in command prompt does in fact launch SFC as expected
See the attached screenshot for reference
