Windows 10: Windows 10 not seeing windows 7 computers after update

After a Windows update this week, our server which runs Windows 10 will no longer see the Windows 7 workstations on the network. All of the computers are set for network discovery, no passwords, file sharing... none of that has changed.The Windows 7 computers see each other and the Windows 10 server, but the server will not see the others.What was in the update and where can I go to change it back to where the server can see windows 7 workstations?Thank you

Windows 10 upgrade problem, no input accepted

I really hate having to come here and ask for help, but I really am stumped. It hurts my geek pride. I have a PC with fairly modern hardware in it. It has a p8p67 pro in it. I have tried upgrading windows 10 on it twice now. Both times I have had the same result.

After windows finishes upgrading it goes to the log in/set up screen. I can't do anything. No keyboard or mouse input is accepted.

I will list some, or hopefully all, of the troubleshooting steps I have tried:

• Move keyboard and mouse to different USB ports.
• Try different keyboard or mouse.
• Restart computer, repeatedly.
• Google for related issues.
• Update Bios, because why not.
• Create boot media and revert to windows 7.

The windows 10 system restore boot media works fine with keyboard and mouse. All USB ports work in windows 7. I don't know what is wrong. I suspect that windows 10 is lacking a driver of some sort, but since the computer accepts no input I have no way of checking for which driver let alone installing it.

Please help me figure this out. If I have to revert back to windows 7 again, I am not going to get it upgraded to windows 10. Thank you in advanced.

Is it time for Windows 10 already?

I can't get update KB3035583 on my windows 7 SP1 laptop, also I was missing the optional language packs updates, I have tried "resetting" windows updates http://www.sevenforums.com/tutorials/91738-windows-update-reset.html and I have tried stopping and restarting the windows update service, did not help.
Would anyone have a suggestion on how to get this KB3035583 update? It's genuine windows 7 SP1 home premium.

Edit: Is this windows 10 upgrade only for people who bought (a computer with) windows 7 SP 1?
I bought this laptop with windows 7.
