@DDD: Your problems are very likely not related to VeraCrypt. You should move over to the Microsoft support and ask there for help. A clean (new) installation of Windows could be a good start though.

Maybe you (as the developer of VeraCrypt) could contact Microsoft and ask them about this issue? I'd imagine that their Windows 10 or Bitlocker developers would know the cause or at least have a good guess. At least it would be worth a try?

@DDD: "encrypt keys in RAM" did not even exist in VeraCrypt when I initially wrote the first post. Also TRIM and Firefox has nothing to do with this issue. If you get a memory dump file or if a problem was logged, it was no freeze but a normal crash, caused by some other problem in your system. If a real freeze (aka dead lock) happens, the complete system is fully frozen in its last state. Disk writes/reads are no longer possible and therefor no memory dumps can be created at this point, also no...

Yes, I was also thinking about hardware problems or incompatibilites with Windows 10 in the first place. I am pretty sure there are more users experiencing this problem (at least from time to time, when swapping happens) but they don't connect them to VeraCrypt, but rather to hardware or Windows problems. I also had a few freezes after prime95 was stopped and Firefox was closed, when the system should go back to normal. I assume that it's more like a coincidence, depending on what exactly was swapped...

Isn't it possible to have both drivers at the same time and depending on what you are doing, use either one? So for file containers the slow driver will be used and for drives/partitions the fast driver will be used?

I also had 1809 installed, but only for 1-2 weeks, I didn't have those freezes there I think. Then the I upgraded to 1903 and kept setting up the system and shortly after the freezing started. At first I didn't know what was causing it, so I was going through the whole system (hardware, software, drivers, etc.) and some days later I figured out it was VeraCrypt's system drive encryption that was causing the freezing. Currently I have encrypted the system drive with Bitlocker, while having the other...

Yes, I imagine how hard it can be to work through all the user requests / bug reports, while also reading through all the threads here etc., thank you for that! I have encrypted the system drive with Bitlocker and performed the same stress test, it does not freeze at all, not matter how hard I push the system ressources. So it seems like the memory usage/handling of the Bitlocker software is not affected when swapping in Windows 10. In fact the system was pretty responsive, I was sort of surprised....
