All of my personalization options aren't working And themes are gone

On Aero troubleshoot it didn't say there was any error, but I still can't enable any theme, or atleast use personalization options.

Do you have Intelbras Media Player installed?

Nope.

However, i didn't have it back when i had to change the specifications of my computer, the personalization options were still working.

I asked because you listed Intelbras as the computer manufacturer and the only thing I could find for them is software. Maybe you can explain that.

I know you're not getting any BSOD's, but I wonder if you would follow the instructions here-

Blue Screen of Death (BSOD) Posting Instructions

and post the resulting .zip file so I/we can look at your system and the events a little closer.

Honestly the only option i have is to format my PC, which will probably fix this issue.

I'll mark this post as solved for now.

Okay.

Let us know how it turns out.
