Can I make windows 7 freeze for a short period of time, during this time I want it to perform absolutely no action. In particular, the OS should not access to any storage device.
My original idea was to crate an interrupt, however, I think that long interrupt will cause a blue screen (which I want to prevent).
I can tell you for a fact that this is not possible - if you do this to the primary volume the machine will bluescreen because of a watchdog timer, even for a short time. If you disconnect the drive, it will immediately bluescreen. If you do this to a secondary volume, it will be surprise removed.
If you have less than a team of 10-20 very skilled NT kernel developers / testers, this idea is not even beginning to be practical. What is your scenario and what you're trying to accomplish at a high level?
