The old issue with WSUS – stuck at 95% still exists. I will leave it on a little bit longer, as TiWorker.exe is still active.

“To restart, select the Start button from the taskbar, click the Power button and choose Restart (not Shut down).

You can also perform a clean restart by holding down the Shift key, then clicking Start, the power icon, then Shut Down. Don’t let go of the Shift key until the machine’s completely gone.”

I think this applies only with Hibernate on (default installation)?
I always disable Hibernate among first things, so I am not quite familiar with the “fast start-up”.
Stand-by is good enough for me and it is used rarely.

I dunno – could be that’s the source of the problem.

Resetting winsock and the TCPIP stack seems to fix it for some…

I am running Windows 10 1607 on my Dell laptop at home. This exact issue began appearing for me on Monday afternoon (12/5); however, the “no internet access” yellow triangle magically disappeared after about 15 minutes and my internet connection was normal the rest of the day. When I turned the computer on Tuesday, the exact same connection error occurred but, again, the error self-corrected after a few minutes.

Same thing happened Wednesday, so I tried some command prompt codes an IT friend suggested to me. I used “netsh winsock reset” followed by “netsh int ip reset” as an administrator. After restarting the computer, it connected without any issues. It has not given me an connection issues yesterday or today, either.

Also, I installed the most recent cumulative update today to go to 14393.479. The internet connection worked without issue before and after the update installed. God willing, those command prompts seem to have worked for me.

occurs ocasionally (around IP renew lease time) I normally hit reconnect to fix then lifes good, if you dont like the CMD line option apparently this works(1607 ver) http://www.howtogeek.com/265870/how-to-reset-your-entire-network-in-windows-10-and-start-from-scratch/

Thanks for the confirmation!

I wonder what got screwed up. Even a friend of mine at InfoWorld hit it.

A rogue scheduled task triggered on Wednesday?
This may explain the rush to release the CU containing the fix early.
Just speculation

well kb3201845 showed up an hour ago, still nothing about the update on the win10 ver page but a curious banner appeared about the above network problem. I guess the folks in Redmond must come to your website for the latest gossip. I guess i’ll leave it “stewing” a while waiting for the usual howls or nods.

Susan Bradley posted on patchmanagement.org a translation from a Dutch language Microsoft Blog at
https://blogs.microsoft.nl/windows/geen-internet-connectiviteit-na-windows-10-november-update/

In essence, KB3201845 is supposed to resolve the issue.
If there is no internet to go to Windows Update, try

ipconfig /release
ipconfig /renew

to get a new lease and allow the installation of the Windows 10 December 2016 update.

Well sunuvagun! There it is, at the top of the Win10 Update History page:

If you are experiencing issues connecting to the internet we recommend you restart your PC by going to Start, clicking the Power button, then choosing Restart (not Shut down).

I still say it’s easier to hold down the Shift button and power down, but what the heck.

Thanks for the eagle eye!

That’s a possibility… Hmmm… hadn’t thought of that!

If Task History is enabled in Task Scheduler, you should be able to see what ran, and when, over time.

netsh int ip reset

from and elevated command prompt works a treat.

I had three Win 10 1607 HP laptops come to me for help with the “could not find a valid IP configuration.” I tried everything including the ipconfig commands with no luck. The “reset network” worked like a dream on all three machines. Don’t know the source; but, follow the howtogeek.com directions and they will solve the problem!

You can reset your network connection – but it’s much easier to simply shut down while holding the Shift key.

How much easier can it be than to go to settings/network and click “network reset” and restart? Easy-Peasy.

Reply | Quote

True. Using the command line netsh is easy too.
