Hi JCL, thanks for replying. When I run a script in SED I can see that drivers are loaded correctly, but after the console saying Compiling scriptname.c [ESC] to abort ........................ the freeze kicks in for about ~10 sec, than the application works correctly again until I exit it or sometimes when switching to an other proces.

I only use Windows Defender as virus scanner and have all windows privacy settings turned on (as in send as little data as possible and run as few apps as possible).
Windows logs also dont seem to give any relevant info / errors.

Also it doesn't seem to be video driver related since when I just started Windows 10 or e.g. when I restarted windows, there seems to be no problems at all.

Tldr: I only can think of memory being the problem. I will try changing the pagefile and see what that does. I have an SSHD (harddisk with a small SSD in it), maybe that is also part of the problem.
