I would suggest returning to your more reliable OS.
Did you ever have an OS with so many problems?
Maybe before the year is over they will have fixed all the problems.
I encountered my Money app needed a registry fix. The runtime broker doesn't even exist in my OS 8.1. Windows photo viewer didn't work right.
It would not play in any other than name order in the viewer or the slideshow.
I found Calendar not installed; I found Themes in the Solitaire also awaiting a future installation. I had to re letter the plug in drive according to instructions obtained again with an internet search after 10 changed it.
In addition, I find that since they put in an update apparently the computer did not go into standby automatically, for 3 days before I restored 8.1. The start menu tiles does not have an uninstall option on them nor a find in file.
Edge has a really nice text only option for news files but it has less functions then Explorer otherwise.
The text to speech voices are missing the British woman's voice in the 10 upgrade.
Cortana is a nice twist on a search application. It has voice recognition of a sort but I usually am typing it out anyway.
The email handler MAIL like on 8.1 has few functions.
The Windows Live Mail download is still much more practical.
These problems should have been foreseen and corrected before the upgrade was launched not left to be fixed from online suggestions by users and by IT people in the institutions that are making the upgrade.
So I believe.
Kudos to Microsoft for at least making the trip back easy.
