[W8.1 Update 1] "Windows Store failed to sync machine licenses. Result code 0x80070490"

I notice just before I have this error another error in Store-Client-UI

Wsreset makes no changes to that

Provider 0 (DiscoveryService) - unable to store result in cache for 0-DiscoveryService-SLS.6.3.9600.0.17031.776.dat

Error: unspecified error

Function: WindowsStoreCache::DoQuery

Source: enduser\winstore\ui\cache.cpp (2066)

Well having the same problem. The command DISM.exe /Online /Cleanup-image /Restorehealth hangs in 20% and then comes with the Error: 0x800f081f

This "Windows Store failed to sync machine licenses." error started 9th of this month.

Hello Ramesh and thank you for your reply.

The sfc /scannow command did return file hash mismatch (same files as mentioned in this thread). SFC could not repair it but running dism /online /cleanup-image /restorehealth did. Subsequent SFC runs no longer show any errors (the App Diagnostic still displays the same warning as in the screenshot from the previous post).

The Display Adapter driver is already in the latest version according to NVIDIA website:

Unfortunately, the error still appears in the Event Viewer:

Hello Emkay,

Thank you for providing a detailed information on your issue. I appreciate the step-by-step troubleshooting and the pains you took to resolve your issue. However, there are a few more steps that we can try to diagnose the root cause and check your system health, in order to fix the issue permanently.

If the troubleshooter has detected that files are corrupted or missing then I would suggest you to run SFC scan independently and check if it helps.

You can also try to update the Display Adapter drivers. If you talk about the drivers then you can follow the steps provided in the following Microsoft article and see if it helps to update the drivers.

Hello,

I have the same Event Viewer error on two different laptops running two different Microsoft accounts. All had the following install scheme: Windows 8 was updated to Windows 8.1 and then Windows 8.1 Update was applied.

I've clicked "Sync Licenses" in Windows Store, I can install applications from Windows Store just fine. WSReset.exe does not help, date and time zone are correct, Windows is activated.

In my case, the App Troubleshooter had returned three warnings:

One with permission settings that it had corrected (though probably unrelated to the issue as Process Monitor did not pick up any "Access Denied" events duing my tests)

Second with "corrupt files" but the SFC output was "Windows Resource Protection did not find any integrity violations." (which may mean that App Troubleshooter interprets the output wrong)

Third with display drivers that might be out of date (which is weird as they are from March 2014 and there is no update on Windows Update)

The Event Viewer message still appears.

Steps to reproduce:

instead of manually starting the task you can also start the following command:

rundll32.exe WSClient.dll,RefreshBannedAppsList

and check Event Viewer: Application and Services Logs -> Microsoft -> Windows -> Store Licensingfor the error message.
