I had forgotten to log in when I posted the comment, I was the anonymous poster 6 days ago :)  

I understand what you are saying, that 7+TT shouldn't be able to be the cause as it does not change any system essential files.  

I do however find it odd, as I have had the problem occur several times now.  

Yesterday I tested it again, I had completely reset my laptop. I installed and used a few essential applications (for me the apps are essential ;-) ).

I installed and used for several days without any problems:
- Google Chrome

- Vivaldi (Browser)

- Typora (Markdown editor)

- Notion (Webapp Wrapper - "notes, blogging, wiki"-like office app)

- Notepad++

- CopyQ (Clipboard Manager)

- ShareX (Screenshot tool)

- Process Hacker 2 (Advanced Process/Task-Manager)

- Listary (App for quickly finding files)

- Discord

I used my laptop again for several days without any problems (like before, I was using the latest Fall Update for Windows 10), I made a system restore point, and decided to test out 7+TT again. About 10minutes after installing 7+TT, I got a BSOD.
