You seem to have quite a few files that have been corrupted in some manner and cannot be repaired. If you are not aware of some incident that might have corrupted these, you might want to try a Repair install. If there is something wrong with your system causing this corruption, you need to figure out what it is?
Repairing 20 (0x0000000000000014) components
Replacement does not match actual file seems to be the major theme of the errors.
cacls.exe.mui
cabview.dll.mui
font-truetype-simkai
mmc.exe.mui
simple-provider-dll
Cannot verify component files for Microsoft-Windows-Microsoft-Data-Access-Components-(MDAC)-
sdclt.exe.mui
Windows Exclamation.wav
Microsoft-Windows-ScanProfiles
sppcomapi.dll
This is just some of the 20 needing repair. You can replace these files, or at least try, but I have not done that procedure.
.mui files are Multilingual User Interface
