I see. So CheckSUR is like chkdsk for the component store, whereas SFC is more of a version fixing tool. So if anything, CheckSUR is the more 'fundamental', low-level tool of the two. Given that there must be some case for building CheckSUR into the OS, or at least making it available as a recommended Windows Update.

Thanks Joseph.

Sure, the reason you want to run CheckSUR first is that it is checking for corrupted binaries and manifests that it knows how to fix. SFC on the other hand is checking to see if the version that you have in the component store matches that of the one on the file system.

If you were having a problem with a corrupted manifest that was causing some sort of servicing issue, it most likely wouldnt be able to be reprojected with SFC, however CheckSUR could fix the manifest and then any further reprojection could take place as it should.

Hi joscon.

For a while I've wondered about the order that SURT and SFC should run in. Now I know, but I'm not sure what the reason is. Could you briefly explain why running SURT is step 2, and running SFC is step 3, and not the other way around?
