Windows 10: All Apps have an Exclamation Mark on over their icon and won't start.

Hello guys, I have the problem that is descibed in my title.
I found this forum by googling this problem and I've tried basically every powershell command I could find with no sucess and now I look for new ideas.

I can't do an in-place upgrade (keeping files option is greyed out) and I'd rather not create a new user account.

Yellow Exclamation mark over Internet icon

Hi,

Thank you for contacting Microsoft Community. I understand that you are getting a yellow Exclamation mark over Internet icon in the notification area.
I will surely help you to fix this issue.

To understand the issue better, let me know what is the make and model number of the computer?

Try the steps listed here:

Method 1:

I suggest you to run the network troubleshooter and check if it helps.

• Press Start Button and in the Windows Search type
  Troubleshooting.
• Open Troubleshooting and select Network and Internet.
• Run Network Adapter troubleshooter.

Check if it helps to fix the issue.

Method 2:

I see that you have uninstalled and reinstalled latest wireless network drivers. However if you have not tried installing latest Wireless Network driver from the computer manufacturer website, I suggest you to try the same and
check if it helps. Also install all the available Windows Update.

Hope this information helps. Reply to the post with an updated status of the issue so that we can assist you further.

 

Yellow Exclamation mark over Internet icon

Hello, I have Windows 10 pro and I am able to connect to my Router wifi without any issues and have a working internet connection. I am able to browse internet and ping my DNS server, gateway etc, no issues but there is an yellow exclamation mark over the
wifi internet icon in notification area. When I take my cursor there, popup says Limited connection next to my SSID!! When I click on it, below wifi icon, tag says "no internet". Earlier this yellow mark used to appear when there was no internet access. What
all troubleshooting I have done:

• Updated the wifi card drivers.
• Checked for any firewall/security software conflicts.
• Upgraded the router firmware and also used another router.
• Changed the DNS from ISP to google to other open dns ip addresses.
• Deleted and recreated wifi profile.

Please suggest what else I can do and if I am missing something. Thanx

 

Can you show a picture of this icon overlay?

Do you use Mozy backup software?

No backup software, this problem occured after using a restore point after problem with Windows where I couldn't get past login screen without it restarting itself.
