Hi,
While running your changed tests, I think I found new failures. Being a bot and all I'm not very good at pattern recognition, so I might be wrong, but could you please double-check?

You can use GetWindowLong() for this, there's no need to add a server call here.

This will add an extra server call for other process window from GetWindowLong(). The two were already there: one for IsWindow(), another for getting rectangle below. I thought it might be better not to introduce the third one. Should I use GetWindowLong() regardless?

Yes. If you want to improve it, you can avoid IsWindow() and check for GetWindowRect() failure or something like that. But either way I don't expect GetWindowPlacement() to be timing-critical.
