hey everyone

its been awhile since ive been here and had been using win7 so i basically knew how to do stuff on it
but now due to a complete system meltdown on my desktop pc, it looks like im going to have to use win 10 64bit now
here is the version on win 10 64bit i will be using
Windows 10 Pro X64 Version 1903 RTM Build 18362.295 19H1 AUG 2019

what win 10 themes can i use on it and how easy is it to patch the system files and other things i have to do
to get the themes working

thank you in advance
