When trying to start Windows 7 in PCem v15 and rev 1494 with the dynarec enabled, it crashes with STOP code 0x7F (UNEXPECTED_KERNEL_MODE_TRAP):
The first parameter 0x00000000 indicates a divide-by-zero error according to [url]https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/bug-check-0x7f--unexpected-kernel-mode-trap[/url]. Also present in the log around the time of the BSOD is the following:
Model: FIC VA-503+, bios revision JE4333
CPU: Any Super Socket 7 with dynarec enabled, but an AMD K6-2/233 was used here
FPU: Built-in
RAM: 512 MB
Graphics: S3 ViRGE/DX
Sound: None
Network: None
Joystick: None
HDD controller: Standard IDE
FDD1: 2.88 MB
FDD2: None
CD-ROM: 72X
Drive 0: 50793 cylinders, 63 sectors, 16 heads for a total of 25 GB
Drive 1: CD-ROM
Mouse: PS/2 2-button
I doubt Win 7 will work on any machine that PCem emulate. According to [url=https://support.microsoft.com/en-za/help/10737/windows-7-system-requirements]here[/url] it needs hardware way more powerful.

There are various youtube videos showing 7 running on hardware of a similar vintage to the configuration posted above (one even went as low as a Pentium 90).
That, and the fact it does work when the dynarec is disabled:
As for Vista, it does run but has severe stability issues when the Dynarec is enabled (can't sit at the desktop for more than ~10-15 minutes without crashing, often with STOP error 0xF4), which disappear when the dynarec is disabled and the WinChip interpreter is used.
