Solved Desktop Window Manager crashing on startup for unknown reasons.

[SrBrunovky]

I just formatted my PC and installed a fresh copy of Windows 7 Ultimate yesterday (Previously had Win10, but I prefer the stability of Windows 7). However, a window pops up whenever i start up the PC saying "Desktop Window Manager stopped working and was closed. A problem caused the application to stop working correctly. Windows will notify you if a solution is available".
This "DWM.exe" is responsible for the beautiful Windows 7 Aero Theme, and because of this error, I have to stick with the shitty grey opaque theme
I've tried to restart it from the "Services", but with no success.
Following, there's a video showing this problem...

Have you installed the Windows 7 Service Pack 1 (KB976932) Being a clean install I would start there.

Oh my god... How could I be so stupid xD completely forgot to install the updates. I was such in a rush to install all the drivers and software, I forgot about them.

Thank you so much xD
