One more issue is said to be affecting a number of users who deployed 8.1 Update

Windows 8.1 Update was released to users on April 8, 2014, but many have actually experienced issues that prevented them from installing the new OS version, no matter if they tried to do it manually or via Windows Update.

While Redmond actually tried to address some of these bugs with the help of new patches or fixes aimed at the error experienced during installation, it appears that a number of consumers who actually managed to deploy Windows 8.1 Update are now struggling to deal with an issue affecting Windows Store app synchronization across devices.

“Windows Store failed to sync machine licenses. Result code 0x80070490” is the error that multiple users are getting after installing Windows 8.1 Update and judging by the number of posts on Microsoft's Community forums, some are still searching for a workaround on this.

A message posted in April by one of the affected users perfectly describes what's happening, while also confirming that some of the common workarounds haven't made any difference in this case. Here's what the message posted by the user reads:

“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.”

At this point, it's not yet clear whether this is a widely experienced error, but there's no doubt that it clearly adds some frustration in the case of users who tried to install Windows 8.1 Update on their computers.

What's worse is that Microsoft made Windows 8.1 Update mandatory for everyone running Windows 8.1, so you have basically no other option than to get it up and running, no matter what issues you are experiencing.

Windows 8.1 PCs that won't be running Windows 8.1 Update until June 10 won't receive any new patches and security updates, with Microsoft explaining that this new OS version is the core of all future improvements, so everyone needs to deploy it as soon as possible.
