Many corrupted Windows7 files, SFC reads corrupted data but doesnt fix

Hello all,

My copy of Windows 7 Home Premium x64 on my laptop has been having some strange issues lately. I cannot run .msi files, and device manager never populates a full list. Sometimes (rarely, but it does repeat) Windows Explorer will freeze, and if I attempt to close it and reopen it using task manager, the UI reloads, but whenever I click on a folder it claims Windows cannot load explorer. Restarting fixes that. I scheduled and ran CHKDSK, and it repaired a few bad sectors, but it didn't fix any of these problems. I have run CCleaner (both the regular cleaner and registry fixer) and defragmented my hard drive until it's only 1% fragmented. I then tried sfc /scannow, and it read a bunch of corrupted files but could not repair them. I read that to fix sfc, you must download and run Windows System Update Readiness Tool. It has been running and "Searching for Updates on this Computer" for about an hour now, and I'm getting concerned that it's just not doing anything. It's not frozen, the bar keeps moving from left to right and I can click on and off of it. I also have the logs from sfc if anyone wants to take a look at them, they'll be attached. The computer isn't very old, and has an intel i3 and 4gb of ram. If you would like any extra information to help, please reply and I'll get back to you as fast as I can Any recommendations on where to go from here would be greatly appreciated.

Thanks so much for any and all help!

Hi Qujibo,
First comment you said ran ccleaner REGISTRY cleaner, this is not advised, unless you know what your doing

If there is an UNDO backup from that utility RUN it.

SURT can quite easily run for a couple of hours.

There are a lot of Winsxs errors in your log.

AFTER surt has run

REBOOT

run the MXdiag report from this link

Was this OS only installed via sysprep a couple of days ago??
