Hi, so my new PC I had to activate it through cmd and connected to a server to activate windows 10, I bought the key from a sketchy website for cheap could it have compromised my PC security and allow me to be hacked?
"and connected to a server to activate" ?
Yes, that could have resulted in many things you DO NOT WANT.
Stop right now.
Do a FULL wipe and reinstall.
Win 10 direct from Microsoft.

When it asks for the license key, skip that portion and proceed on.
This will be Unactivated, until such time as you choose to purchase a
valid license key. Generally around $100.
It will run just fine, with the few small restrictions that come with an Unactivated Win 10 install.
Beyond that, you'll not get any assistance here with pirated software. None.
