How many levels of priority are there in MS Windows OS?

I think it is 32. I just wanted to confirm

I believe you are correct but...

A quick search turned this up:

Kim: INtime's kernel is derived from the grandfather of all RTOSs, iRMX from
Intel. Having been in use prior to MS-DOS, no other RTOS technology has been
tested and refined to operate PC hardware with higher precision and
protection. Upon generating the system, INtime resides in its own virtual
machine protected from anything going on associated with the Windows
operating system. As a fully protected operating system itself, your
INtime-based real-time application also runs fully protected from all other
processes as well.

I know of no other solution that provides this level of protection and
reliability in addressing deterministic control issues with Windows XP
systems, and none that is as extensible as INtime. Using INtime, you are
free to add up to 8000 objects to your real-time application. This can allow
for the most sophisticated and taxing system conceivable, all with higher
priority than anything occurring on the Windows side. INtime features
numerous dedicated real-time interfaces including a TCP/IP stack, USB, a
wide variety of industrial control interfaces, and COM drivers. The
operating system supports 256 levels of priority, round-robin scheduling,
and interrupt support, all as services accessible from your user-mode
real-time code.

Re: Priority Levels

You're referring to thread priority levels, I suppose.

Yes, there are 32 priority levels, from 0 (lowest) to 31 (highest priority).

There is a lot of literature on Windows scheduling at the Microsoft website.
For example, I've found this link:
