Anyone have a good comprehensive guide to optimize and get rid of all bloatware/unnecessary applications and general things I should do on a new OS?

Most of it you can't, Lul

which version?

haven't got a clue
where do I check?

Press windows key

Type "system info" hit enter

Version 10.0.14393 Build 14393

Pro? Home?

Lol I completely misunderstood your question.

I just left to run a few errands so I won’t be able to check for an hour or two.

I had ultimate before I sent it off to get fixed and it returned with a fresh install of windows so I’m not sure what version they used.

start by reformatting and getting a windows 7 bootable usb

is windows 7 even useful anymore? does it support dx12? arent benchmarks way better on win10?
