My DISM doesn't have the scanhealth option, an error is displayed when I try to run it

[System]

I seem to have that problem a lot of people are having with installing the security update for .NET 3.5 (KB2789650). I kept getting an 0x80073712 error so I tried following some of the recommendations I found here but they didn't work. I was able to turn
the .NET 3.5 features on myself through the windows update window in the control panel, but the update still wouldn't install.

I can't even open the windows update window anymore, it keeps freezing. I tried to troubleshoot it and fix the windows update and this is what I got:


Issues found
Potential Windows Update Database error detected 0x80073712 Not fixed
Repair Windows Update Database Corruption Failed
Windows Update components must be repaired Fixed

Then I tried to do the scan health stuff DISM.exe /Online /Cleanup-image /Scanhealth and DISM.exe /Online /Cleanup-image /Restorehealth but I got this error:

The online/cleanup-image/scanhealth option is unknown.

Then I entered DISM.exe/? and this is what it showed me:

I'm really frustrated with all of this, is there any possible way to fix this without refreshing my pc? I rather not have to reinstall all my programs again. Even the system recover makes my computer freeze up.

I would really appreciate the help!
