The saga continues - the issue is why can't I do what I want.
This is a reminder of immediately after my first install of Windows 10 I disabled UAC using windows 10. Boom. Windows 10 rebooted and reinstalled itself. [Why not block it?]
So, here I am. I had installed au 1607 and everything was good except I was trying to install my deejaysystems video player.
Logged in as DefaultAccount. I went to File Explorer | Manage Computer and clicked on several users and turned off password change and added them to Group Users. Then, I went to User Administrator and tried to add Group Users to it. I just wanted everything to work. Windows 10 Hung. [Maybe I didn't wait long enough.] I thought I had screwed up something so I logged off.
Back to Manage Computer. Now, "This file has no program associated with it." So, I went to Shut Down. Windows 10 reinstalled itself. However, all my installed software like Word, Excel, Access, DeeJaySystems, etc. missing.
Thanks to all that is good for you. I pulled out my au 1607 disc and reinstalled. Programs found and Manage Computer worked. I was so happy. BTW, at this point, when I click on User Administrator, it shows member of "Users." Perfect.
I am still trying to get subtitles to show up on DeeJaySystems. I think it's a permissions issue because it did work for a minute before the latest sequence of installs.
One more thing. Now that windows update is working, I have a KB4019472 Cumulative Update for 1607 for x64 Systems. Fails to install. I clicked on install updates and shutdown. Must have taken more than an hour to install the update and then issue a note that the install failed and then backed out the update. Everything still worked. Yea. Again, Install Updates and shut down - same thing all over again. So stop Windows10 AutoUpdate:

They work on MPC [Media Player Classic] which I think has its own subtitles manager but not on DeeJaySystems using K-Lite Codec Pack version 995 which is the suggested version. I had it working on Windows 7 so maybe something has changed in Windows 10.
Anyway. THANK YOU SO MUCH FOR THE LINK TO AU 1607 - Saved my day, and gives me a base for reinstall if something crazy happens. [again!]. Have a great day!
