Need Help MS10

OMG... ok, so at the risk of dipping my toe into shark waters, I still can't help myself and have to try to assist and clarify some stuff in this thread.

First, the Windows 10 free upgrade ended over a month ago and the "nag" messages are gone. So it is a grand mystery how a computer could do said upgrade "automatically" without paying for it now. (kinda)
There are only two ways that a computer can do the Win 10 upgrade now for free. The first is if you "began" the upgrade before July 29th. Don't laugh - this is a real possibility. Many users got that nag message popping up for months and one of the options was worded something like "Download but defer the upgrade until a later date." So, especially for those who use the phrase "I'm not a computer genius," it is well within the realm of possibility that they "clicked something and it went away." Well, depending on "what" they clicked they may very well have downloaded the upgrade tool which would have begun the upgrade for a later date AFTER July 29th.
The second way is still active right now. MS will give it to you if you declare that you use "Assistive Technologies." This is part of their charity outreach stuff. It provides Win 10 for free to those who are vision, or hearing, or otherwise physically or mentally impaired. (link: https://www.microsoft.com/en-us/accessibility/windows10upgrade)
And, you can easily revert back to your previous OS within 10 days of the upgrade if you don't want it (link: https://support.microsoft.com/en-us...37070c/going-back-to-windows-7-or-windows-8.1) The only way this does not work is if you force-ably told it do do a total erase and fresh install.
And the upgrade does not "flush out" old versions of Office. The system I am on right now is running a very old Office 2000 suite still just fine after the Win 10 upgrade. However, I do suspect that if I tried to RE-install Office 2000 right now that it wouldn't let me, but it KEPT everything that was previously running on Windows 7.
To make matters worse, you had a virus (RealImage) which is the likely cause of any "flush" of AVG or printer or a variety of the other reported woes.
Then you had another thing that actually is afflicting us all after the upgrade. (so this one threw the train further off the tracks and compounded your situation.) Windows 10 DOES indeed perform some shift trickery with what they call "Default Programs." One of those shifts is an integration that they are trying to do by forcing all PDF files to open with the new Edge browser now. So your screenshot was showing an Edge admin permissions error when you were trying to open an Adobe PDF file with Edge (and not an Excel or Office issue like others have stated earlier as well.) It actually uninstalled Adobe Reader from multiple machines on me. That is the only program that I have seen it do this too so far (i.e. actually UNinstalled it.) My recommendation is to reinstall the actual Adobe Reader like Mark posted earlier with the link and not allow Edge to try to be the default.
Continuing the last paragraph, after upgrading to Win 10, you should do a search down in the bottom-left menu area (also now called "Cortana" if you did not disable Cortana as I did) for the word "default." On of the options that comes up says "Default Programs." Click "Default Programs" and you will go to an area where you will see that Windows 10 probably set several file types to new Win 10 version apps. Adobe PDF is one of them. Another common one is if you had the very excellent VLC Player for all of your video files. It probably set the Windows 10 entertainment player as the default and you would need to reset VLC as the default. Etcetera.

Finally, my opinion of Win 10. As was stated several times here, Windows 10 in my opinion was a no-brainer over the hybrid mess that was Windows 8/8.1. However, if you had Windows 7 then it was less compelling to upgrade because Win 7 is an excellent OS. However, I still upgraded even my Win 7 machines and am happy with that choice personally. BUT ONLY HAPPY AFTER closing all of the security and bandwidth hole that came with Windows 10. There is a reason that it was free and went on 350 million computers in 12 months - they partially adopted the Google Android business model of selling "you" instead of selling the OS.
Go to that same search (or Cortana) in the main menu and type "privacy" and then click "Privacy Settings." An entire laundry list of items running all the way down the left will come up. Almost all of these can be shut off as they are all sending data to and from MS. Look especially for phrases like "Stop Getting to Know Me" ha ha. Yes, it actually says that. In addition open the Windows start menu and all of those pretty tiles come up. For those who are concerned with burning cell data bandwidth (as well as privacy) you should right-click on those that you don't need (unless you actually play Candy Crush for instance) and "Uninstall" them. And for all those others that you keep, right click on each, click "More" and click "Turn live tile off."
If you are particularly worried about it burning cell data, you can type "Airplane" in the search and turn airplane mode on to temporarily halt all data usage until such time as you turn it back on.

My two shillings for what it is worth.

 

That's so sad...
Hate to see MS go down that path.

"Stop Getting to Know Me"... Too funny!!!

 

But to read the pdf's for the user manuals you have to have Edge for the PDF reader. See my procedure earlier. These are the users manuals for the TND models

 

What??? Nah. I don't use Edge to read PDF's.

 

I kid you NOT dude!

 

Off the Dock for the TND

 

I think you just demonstrated the "default" point above. Edge sets itself as the default PDF reader when Win 10 installs. Go to search / type "default" / click "default programs" / scroll to bottom in the middle / click "choose default apps by file type."

I bet Edge is set as your default reader. My PDF's open with Adobe reader from the dock.

 

I have adobe set to default but when I try to open the pdf from the dock I get an error msg. Will try again and post when I get home

 

I'm gonna have to go home and play with a pdf file. This is the first I've heard about this edge. I've had no problems using adobe.

 

Edge is the replacement for Internet Explorer. In fact I recommend you do not use IE at all at this point. Use Edge, Chrome, or Firefox on Windows, and Safari only if on a Mac. IE is dangerous at this point as it has been abandoned like an old sock. If you did the Win10 upgrade then Edge is now the default browser unless you designated one of the aforementioned others. And that isn't bad news either. So far I like Edge far more than IE. I just don't let it override Adobe for opening PDF files. But it does act more like a nimble browser (like Chrome) and much less like a dying mule (like IE.)
