Windows 7 machine working fine. Finally gave into to win10 nag screens. Installation failed, clicked on revert and relieved when all came back. BUT browsers don't connect to interest. Network connection map shows fine connection, both wired and wifi.
cmd - ping 8.8.8.8 - gives response.
Others here say try "ipconfig /flushdns"
Then tried "nbtstat -R" and get error "failed to Purge the NBT Remote Cache Table" . Have tried this under two admin accounts, can't get further.
Help please!

OK< finally solved myself!
key thing is you need to "run cmd as admin" - this does not mean from a user account that is administrator, but type "cmd" in the box from the windows icon, then do not press enter as usual, but right-click and select with mouse 'run as administrator' - then you get the same window, and these commands all work, then IE, chrome etc start to work again.

ipconfig /flushdns
nbtstat -R
nbtstat -RR
netsh int ip reset c:\resetlog.txt
netsh winsock reset exit

Now the question is do I try the downgrade to Win 10 again? or risk withdrawing support from win7 as per perfectly functional win XP?

Try this

For Windows 7 and Windows Vista

To open a command prompt, click Start and then type cmd in the Search programs and files box.
Under Programs, right-click the CMD.exe icon, and then click Run as administrator.
When the User Account Control box appears, click Yes.
At the command prompt, enter the following command, and then press Enter:
netsh int ip reset c:\resetlog.txt
Note If you don't want to specify a directory path for the log file, run the following command instead:
netsh int ip reset resetlog.txt
Restart the computer.
