Little side note
those computers in question had either i5-4750 (I think?) or i7-4970 so running windows 10 with all its bloat was not going to be an easy task
The i7-4790K is still quite powerful, so I’m pretty sure this wasn’t the problem, at all. Perhaps they’re running on an HDD, have little RAM, or you got the CPU wrong.
You can see the CPU and RAM by launching System Info from tbf start menu, and see if it’s running on an SSD or HDD by launching Disks from the menu.
Ah, my bad (^^;
I ran an i7-4790K in my gaming PC for a long time, as far as games go this 10-year old CPU still hold up well, never had to upgrade it surprisingly enough!
Still, a 4 GHz quad-core with hyper-threading, and about 8 GiB of RAM, is more than enough to run Windows 10.
Assuming these are for studying, the heavier workloads would consist of MS Word, Powerpoint and an instructional video in the webbrowser, no?
What required tasks were too heavy for these computers under Windows 8/10?
And do they run off SSDs, or spinning HDDs?
