Ok, this issue is solved for me, but I have another issue... random BSODs... Vista is just unstable on Ryzen, it can give you random BSODs with random codes (IRQL_NOT_LESS_OR_EQUAL, BAD_POOL_HEADER, etc), and seems that we need to contact win32 (creator of Windows Vista Extended Kernel) about this issue, but seems that he is active only on msfn.org, and I can't sign up to msfn.org because e-mail just does not arrive to me. So, @George King, could you contact win32 about this issue, and, if possible, bring him to this forum, if he is not in this forum? UPD: I found some person called @Win32, maybe he is real win32 UPD 2: No, he is not real win32
