when i use hypersli it gives me these problems

My guess is that hypersli uses modified hal.dll (or, probably ntoskrnl too).As Win 8.1 may need special tweaks including ACPI patches etc, hypersli may break that.

You need to run non-updated windows 8.1, later updates on win 8.1 and win 7 break it

thanks for the replies. so if i use a win 8.1 from 2021 it should work? now i use a 2024 one

Just use original msdn image of 8.1 from 2014

A thousand thanks
