Are there windows operating systems in the satalites?

The only thing those satalites need to do is, accept signal, do math, and transmit signal.

I don't see why you would use Windows for this.

The satellites themselves are most likely running some sort of proprietary or semi-proprietary RTOS for their C&DH computer (eg: VxWorks, QNX, Integrity, RTEMS...).

However, it's more than likely that there's a bunch of Windows machines on the ground segment side of the operation, since a lot of satellite fleet management software is Windows based.

Nah. The ground control segment software runs a version of the ESA's SCOS 2000 https://en.m.wikipedia.org/wiki/SCOS_2000 and is on Linux (and maybe Solaris).

Do you need a windows os to send a signal to the satalites?

No.

But for some reason the op implied windows was to blame without evidence.

I mentioned the implausibly of it.

Op is misleading people.
