Prompted by recent issues I have been experiencing with MS Office Pro + 2016 over the last week, I believe since the last Windows update to my then current version 1809, all Office app's. unable to open, package had to be "on line" repaired and re-registered, I have bit the bullet and upgraded to Win. V.1909 in the hope that will address the MS Office issues.
Always suspicious of MS Win updates unwanted bi-products which MS very rarely admit to !
Since a previous bad experience with V.1903 I had opted out of any Win feature upgrades.
Certainly was not a quick process on either my Ryzen-5 or my dual boot, Win10/Linux Mint i5 PC's, took close to 2 hours each, to expectation I suppose as I had skipped V.1903 previously.
Both PC's currently appear perfectly stable under V.1909, hoping that my MS Office issue will also be cured on the Ryzen-5 PC, had occured twice in the last week running V.1809, time will tell.
Edit:
Typo correction.
