Ever since I upgraded to windows 10, my game window is shrunken down to roughly a quarter size of my monitor. I've tried a lot of different things like different compatibility modes, uninstalling and redownload games. I'm running out of answers. The games I'm trying to open are all the games from the Command and Conquer: Ultimate Collection.
Command & Conquer 1, Red Alert 1 and Tiberian Sun have all been upgraded with community-created unofficial patches that fix a lot of their bugs and compatibility problems. You can find them here:

For RA2... there's an option in the compatibility settings called "disable display scaling on high DPI settings". Apparently it affects that. Besides that, I also advise installing the graphics system patch DDWrapper; it's known to solve a lot of issue on RA2. Download the zip file and extract "ddraw.dll" and "aqrit.cfg" into your game folder. Then, open the configuration file "aqrit.cfg" in Notepad, change the "ForceDirectDrawEmulation" option to 1, save the file, and the game should work.
For the games after RA2, I sincerely doubt you'll have that problem, since, unlike the older generations, those games have scaling UIs that adapt to your game resolution. So to fix those games, just set them to your native resolution. There are sticky topics around here that'll help you with creating their config files.
