I have no idea why the background so gray. 

The article is about Windows 98 Second Edition - you serious?

I've searched thru Technet and found no answer as well.

The issue is that ICS works until reboot - and then stops until re-enabling - doesn't look like it doesn't work at all. It seems like the problem is in route tables as they differ before and after re-enabling ICS - and i have no idea why they should.

You can try to run the Network troubleshooter. Type Network troubleshooter in the search box and then select Identify and repair network problems. Make sure to check that Wi-Fi is turned on for your device (including any physical Wi-Fi switch), and that airplane mode isn’t turned on when you are using wireless (Wi-Fi) connection. Ans also check that the cable is securely plugged into your PC and your router or modem when you are using a wired connection.

Updated network adapter driver will also help resolve the issue.

Troubleshooter has not detected any problems, drivers are newest and the issue is still there.

New build is coming though, i'll let you know after OS is updated.

in 15042 the issue is still there,

i ran Network Troubleshooter before and after re-enabling ICS and re-setting IP-address, saved detailed network configurations and compared them - they are identical.

Hello. I recently upgraded PC, made clean Windows 10 re-install and unfortunately the issue is still there despite having new equipment (And it cost me Insider license, well done.) I reported feature for like 3 times using feedback hub since the patch it started to happen. Can't see anything was done about it. After update I got like 14K build and Windows eventually get updates at slow pace despite I am having "fast" builds setting, so currently I am at 15048 rs. When it at last gets updated to latest build and if the issue is still there i'll report it with Feedback Hub once again.

It seems I found the root of the issue. Upon restart the Service "Internet Connection Sharing" is not in "started" state despite having "Automatic (Trigger type)" startup type. Simply starting it causes ICS working well. What might be the problem ICS service doesn't get started?

Also I found some guy started similar topic for newest build:

May be it's a time to get some work done?
