Issue: How to Fix Windows 10 Default Apps Missing After Updating (Error Code: 0x80070776)?

I’m still using Windows 10 Version 1607, which I’m satisfied with. Since today, I did not plan to upgrade to version 1703, but the issue on my PC made me doubt whether I should switch to Creators Update or not. I have installed Cumulative Update KB3201845, which wiped all default Windows 10 apps, including Edge, Store, Photos, and so on. What solution would be the best in my case? By the way, I get the error message with a code 0x80070776.

Solved Answer

Few people reported a Windows Anniversary Update Error Code 0x80070776. The error shows up after installation of the Cumulative Update randomly, but the error itself is not the biggest problem. It points out to the problem, which is missing default Windows10 apps.

While initially it seemed that the problem is bound to the Cumulative Update for Windows 10 Version 1607 (KB3201845), the latest research revealed that the same problem may occur with any Cumulative Update. On top of that, there were similar cases with missing Windows apps after the installation of the update on the Creators Update (v1703).

Actually, the culprit of the 0x80070776 error and missing default Windows 10 apps is simple – unsuccessful installation of upgrade/ update process, which omit the stage of registering the default apps by mistake. There are several methods that would help you to solve the problem.

Method 1. Check the system for malware

Cyber infections, such as Trojan, Worm, Ransomware, and others are capable of initiating various systems’ changes, including removal of default Windows 10 apps.

• Now copy and paste the following command in the PowerShell window:

Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\\AppXManifest.xml”}

IMPORTANT: do not use italized quotation marks because the command won’t work. The quotation marks must be straight.

• Finally, press Enter and wait while Windows is downloading and registering the default apps. Although it might seem that nothing is happening, do not press any keys. The process requires some time.
• After all, restart the system.

Method 3. Uninstall the Update

• Click Windows key + I to open Settings.
