Another option I used when I didn’t want to use my iPad, was an inexpensive Amazon Fire HD8. You need a micro SD card to separately load the ExploreStars database, but I had great luck with it. Your Windows laptop should do this fine. It is a modified Android device. Just make sure the ExploreStars app is still available from the Fire App Store. I think mine was a 32mb unit.
I certainly understand your frustration, but the mount really is a great product. I have been there.
