After a clean install of windows 8.1.1 using the ISO from Technet I started getting the following error message in my event log the first time I start my machine in the morning:
Event 512 Store-Licensing "Windows Store failed to sync machine licenses. Result code 0x80070490"
I use a Microsoft account and I have synced by Modern apps many times manually. Running the scheduled task manually will also produce the same error. I disabled the Scheduled Task that runs the sync and I'll see if it shows up tomorrow. Btw, the Store seems to be working fine.
I read somewhere that the MS Store will be changed for 8.1.1 so I wonder if the 'new' store will stop these messages.
The Scheduled Task that kicks this off appears to be Microsoft/Windows/WS and is called WSRefreshBannedAppsListTask.

Ok that explains it. However i'm not using a Microsoft Account, i'm using a Local Account and have no Apps from the Store installed at all. The preinstalled Apps that shipped with Windows 8.1 were all uninstalled. This was a clean installation with a 8.1 Pro x64 OEM/SB version. Not sure why this is also happening with Local Accounts but since I don't use the Store I can probably leave it like this to avoid the error messages being logged.
Kind regards
I believe that is because the task checks what Windows Store Apps are installed for the user that is currently logged when the task is executed. The SYSTEM user has no Microsoft Account (unlike a regular user) and probably has no Apps installed. Another way to put it - when the task is set with default parameters it executes as "yourself". If you change it to execute as SYSTEM it executes as SYSTEM.
Running the task as the user (not as SYSTEM) is probably needed to get the information which Apps were downloaded/bought by the user for license check. If the task runs as SYSTEM, it may not detect any Apps as nothing was downloaded from Windows Store as SYSTEM. As such the task may just gracefully exit without any information nor without logging any errors (as it may had done nothing).
I don't understand how this can be a server side problem when executing the WSRefreshBannedAppsListTask task as the SYSTEM useraccount finishes without the error being logged. It was never logged again here since I changed it to SYSTEM.

I believe this is a plausible explanation as to why the error had disappeared for some people. But ultimately, it's just my guess...
