Error 0x80070003 in Windows Store

For support purposes I have a machine I keep on 1511 using the 'hide updates' tool. When 1607 recently became CBB its status had changed and I had to hide it again - it was effectively a 'new' release (or more accurately a re-release). That probably explains its reappearance on your machine.

CBB=Current Branch for Business? Meaning that business versions get updated more slowly because they need to be more stable, or something like that? And I'm assuming that 'hide updates' is only for Windows 10 Pro?

There are quality updates with security/bug patches (cumulative updates) and features updates (1511, 1607, etc.) which upgrade the OS to the next version. Which version is current for you depends on which service branch you are on. Most of us are on the Current Branch. Business users get features updates later, but everyone gets the latest security fixes. Insiders get the features updates ahead of the rest of us to test/debug them. Microsoft explains how it works here...
Overview of Windows as a service

Pro can defer updates, effectively switching it from CB to CBB. It's 'defer', not 'block' so they will get the features updates when CBB does. There is a tool from Microsoft that can hide updates, useful if a driver update causes problems for particular hardware. This works on Home and Pro alike.

Interesting. Thanks for the explanation.

So my computer has updated to Creators Update now, and I'm getting a similar problem. Apps like Photos and Groove Music won't open - they just hang on the loading screen, and Windows Store does the same. However if I leave that for a while it does load properly but it has a load of app updates that aren't going through. All of them said Error - see details (the error code is 0x80080005) and when I tried restarting the download a few of them started saying 'acquiring licence' but nothing was happening. I just wanted to seek some advice from the people here - should I just wait for the next update/patch in the hope that it will fix this or am I better off downgrading back to the Anniversary Update (under which everything worked fine for me)?

N.B. I ran wsreset.exe and also the Windows Store Troubleshooter, the troubleshooter found that "service registration is missing or corrupt" and said it was fixed but this didn't resolve the problem.
