Does anyone know why my Adobe suddenly started saving all my "PDF's" as Chrome HTML Documents?  How can I fix this?!>!

April 2022 UPDATE. These instructions from krishnaa0205 no longer work (MS has made changes). Here are VERY SIMPLE instructions to fix this issue. You can watch a quick video from Adobe support, or scroll down below the video for step-by-step instructions with screenshots.

I am having the problem with my pdfs and google chrome. I followed the instructions:

Click on MS icon on left corner of the task bar (4 rectangles or windows sign)2. Right click > Control panel > Control Panel\Programs\Default Programs\Set Associations3. Sort by Description (Other available options are Name, Current Default)4. You will notice that the (Adobe Acrobat Document) PDF files have been associated with Chrome

The problem s that the control panel doesn't appear with I right or left click. The only way I can get to it is if I do a search. Then I open it, click on Programs, then Default Programs. There is no Set Associations at that time. My choices are: Set your defult Programs, Associate a file ype or Protocol with a Program, Change AutoPlay Settings, and Set Program Access and Computer Defaults. I've gone into each of these and cannot find the next step. I'm at a loss. Can anyone help?

Well, I noticed everyones answer but many of them didn't solve the issue for me. If anybody else said click on a pdf file within file explorer, right click on Properties, Opens with . . . . CHANGE to Adobe Acrobat, Apply, OK I would agree
