Okay, I have disabled TRIM now. With this command:
fsutil behavior set DisableDeleteNotify 1
The Runcore 64 GB is still installed. I wonder if disabling TRIM has an effect on the infrequent BSOD crashes. If not I am convinced that Runcore is overpriced crap.
Disabling TRIM seems to work for others, though. Please read this:
l am not alone with a Runcore that has BSOD issues. It's my 2nd one with this problem. The first had the old 1819 and the new one has the 1916 Firmware.
