Undo won't work MS Word 365 on Windows 10

In the toolbar at the top of Word, the UNDO option no longer works. Save, Redo, and Speak still function properly. Since Windows 10 upgrade, any program I open uses so much memory and CPU, typing and deleting are jerky and slow, so I use undo a lot. What the heck???

    Lisa, same problem with my Undo. I'm curious. Is your Word acting jerky, as in, you type a sentence and the letters sporadically dance across the screen? Is your program freezing up and going 'white', but not recovering your files? I've encountered random glitches over the years, but this has become a 'dozen times a day' issue for me.

    I've given up, Kathryn. It took me hours to edit 23 easy pages yesterday and I can't handle those delays. I'm going to restore my laptop to factory settings and hope for the best! 

    But, I'll stay tuned to this thread in case the problem comes back. :-/

    Did you try Safe mode, as Doug suggested?

    If things work properly in Safe mode, that suggests a poorly designed add-in as the most likely cause of trouble. (Note that Safe mode is for troubleshooting only.)

    I totally feel your pain. I used the Fix It option this morning. It took running it twice and reinstalling Office twice before I gave up and installed Office 2016. Yes, four hours wasted again today, but I'm happy to say so far it is working. Good luck. I managed to finish my edit today. I'll cross my fingers for you!

    I received an email from MS asking if my issue had been resolved. The answer is a resounding NO! I uninstalled 365 using the Fix It option. After three tries, it was finally successful. I then downloaded Office 2016. Yes, I restarted my computer. Yes, I followed all the steps correctly. Unfortunately, the UNDO button randomly disappears in 2016 too. I believe this is a Windows 10/Office problem. Something in the programs are not quite compatible, and I'm worried this problem will remain for a very long time, and therefore creating problems for both my clients and myself.
