Can't Start Windows Update. Says File Missing.

How can I post my log here?
I don't know much about computers and something is going on after updating.
I work in 6 hours and I gotta go to sleep but will come back when I wake up.
Also my audio has been disabled which is weird.
No realtek update works, and when i uninstall audio driver windows keeps installing hd audio drivers.
does my computer think it has windows 10?

Please follow the Windows Update Posting Instructions
and post the requested data

If the file is too large (8MB compressed), remove the older CBSPersist cab files until the final file is below the limit - you can always post them separately after zipping them. (the forum doesn't allow the upload of bare CAB files, for a number of reasons)

Please also post the C:\Windows\windowsudpate.log file

hmmm...my windows doesn't want to open the MSU file?
it doesn't know what program to use?
can i open it in cmd.exe?

However ... the utility which actually executes the *.msu is WUSA.EXE, the Windows Standalone Update Installer.
So open a Command Prompt "As Administrator", and run this command:

WUSA <path>\Windows6.1-KB947821-v34-x64.msu

to install the update.

what do i select to run/open an .msu file? - Microsoft Community

I added the file name in that, as long as your path and file name are correct it should work for you.

at first it said i couldn't find the file, now i did it and it said access denied.
my lunch break ends in half an hour so i'll be back soon

i did the DISM.exe /Online /Cleanup-image /Restorehealth

and it said error 87.

so i'll be back soon, my lunch break is over.
do you guys need my PC specs?

do you guys want the DISM.log error file I got after trying to use command prompt to open the MSU file?
