Acrobat 2017 and Windows 10 - Crashing/Freezing

I have to clarify, when I said to run the troubleshooter I meant to goto settings (or  Control Panel) and run the Compatibility Mode Troubleshooter just for the application that is misbehaving.

Even though  Adobe Acrobat is inherently a 32bit application that has been tested to run in 64bit Windows family of operating systems,  the application may behave with newer updates that are now aimed to support 64bit only environments. That said, quite afew announcements has been published by Microsoft in regards of End-of-Support or End-of-Life for some products that were previously supporting 32bit applications such as Adobe Acrobat , for example.

Since the Adobe Acrobat was working before, we want to test an earlier version of Windows with it with the Compatibility Mode troubleshooter; this will reveal or rule out if the problem is actually related to  a bug in Adobe Acrobat (like many users are claiming) ; I suspect is more related to a 32bit vs 64 bit  compatibility issue rather than a bug

We have the problem of freezing when trying to save a file after editing.  Not always, just sometimes.  After selecting CLOSE, then SAVE, it freezes between the action of selecting SAVE and moving on to the list of folders in which to save it.  Just keeps spinning and spinning and not proceeding.   Sometimes we'll use TaskManager to End Task for adobe, then going back in and editing the document a second (or third) time then selecting SAVE again will work.  But when it takes 2 or 3 times and it's still freezing we've restarted the computer as that seems to clear Adobe Reader for awhile and allow it to work properly.  But eventually after signing/editing a few documents, CLOSING, then saving the edited version to our harddrive Adobe will once again  freeze up during the SAVE process, won't clear itself, so we have to shut down again.  At which point we relent to the old ways of printing the original unedited file, signing/dating the hard copy, then scan it back in to have a final pdf version to email back.  Extremely annoying and time consuming. . ..   Have tried to analyse if it works best SAVING via the FILE menu option of SAVE AS, or selecting the toolbar SAVE, or any other alternative steps we can think of to change around - but nothing seems to be a permanent fix and know of several others with the same issue.  FYI Windows 10 came with this computer and regularly get updates for it and Adobe.  We use Word Perfect X9 for word processing.  So if it's our document we'll draft it in WP,  SAVE as a pdf, then edit the pdf by inserting a signature and SAVE again as a finalized pdf version.  OR if its a document from someone else from email we'll open it, date and sign the pdf, then SAVE the final version.  So who created the pdf (and what version of adobe may have been used) doesn't seem to make a difference.    

A caveat on upgrades to Windows 10 from Windows 7:

Were the upgrades to Windows 10 performed on top of the already installed Windows 7, OR, did the upgrade was performed as Microsoft recommends? (meaning, wiping off Win7 for good out of the hard drive, repartition the drives, format the drives, perform a full windows 10 install while connected to the Internet to receive updates as the installation runs?)

I would be sure that you have the most recent updates to both Windows and Acrobat installed (if possible - I understand the restrictions in a corporate environment).  For what it's worth, my installation of Acrobat on Windows 10 is very zippy, and I haven't had that for quite a few iterations over the years.

My best,

Dave
