No DNS after downloading and installing latest Windows Update
I'm not particularly techy so I hope I describe this right.
I have a Toshiba laptop running the 64bit edition of Windows 7 Home Premium. Service Pack 1 is installed.
A couple of weeks ago, I was routinely automatically downloading and installing from Windows Update. Then at my last Windows Update, after it had finished installing, DNS simply would not resolve, then it started to but very very slowly and then it stopped again. I could use IP addresses just fine, but DNS would simply not resolve, or would do so very slowly.
Reading around, I tried the following:
1) Removing the Microsoft Virtual WiFi Miniport Adapter completely. This seemed to work at first, and then it just stopped again.
2) Changing the preferred DNS to 18.104.22.168 and, when that didn't work to 22.214.171.124. that didn't work either.
3) I shut down all anti-virus/firewall - still didn't work.
I ended up taking Windows back to a System Restore point pre- the latest Windows Update and everything was fine again. Now I'm worried to run Windows Update at all. If anyone has any ideas about what I should be doing, I'd be very grateful.
Thanks in advance.

You can avoid having to do this if you can figure out which update is causing the problem and then you can right click and hide the update.
This particular update has been causing problems for awhile now but if you happen to reinstall that update then running this command might help.
Lets try flushing DNS cache and renewing your IP.
Flush the DNS cache and restore MS's Hosts file ...
Copy and paste these lines in Note pad.
attrib -h -s -r hosts
echo 127.0.0.1 localhost>HOSTS
attrib +r +h +s hosts
netsh winsock reset all
netsh int ip reset all
shutdown -r -t 1
Save as flush.bat to your desktop. Right click on the flush.bat file to run it as Administrator.
Your computer will reboot it self.
You might need to reboot twice for this to work.
