On another note, the update this week included a security update for Adobe. Now my imported files don't fit on the screen when pulled up until after i click on the actual document. SO it now takes 2 clicks to see anything that has been imported. My computer is the only one where this has happened.
I think you have half the battle won. If you know the particular update, you can go to Control Panel > Programs and Features. At the top left there is a selection for uninstalling updates. You can uninstall from there. If you want the security, you can go directly to Adobe to hopefully get the fix. I almost always prefer the usability over security. But, that sounds like it was more Adobe's issue than Windows. If Windows is the evil empire, then Adobe is...well I can't come up with anything that sounds worse. You would think that with Adobe going to subscription software, which I have done once but likely not again, they would have enough money to have secure software to begin with. Adobe Acrobat DC, etc. is a lot like Office, especially Word. You can use one of the apps for years and only scratch the surface of the "features."
Oh, you can get to the updates for reading about them directly on the site and for uninstalling at the Update settings. It's the same page where you set active hours. The setting to click on is just a little above. It's actually not bad the way it is set up. It takes you to a page where all the install updates are hot links which take you to the Microsoft page, and you can click on the Uninstall Updates at the top left. It takes you to the same place in Programs and Features. I believe that "Features" is an oxymoron.
