Microsoft is Reprocessing Store Apps to Fix Error 0x800B0100

Microsoft has acknowledged that Windows 10 users may see error 800B0100 (TRUST_E_NOSIGNATURE) while installing certain apps from the Store and is working on a fix.

“We are sorry about this failure and are actively working on mitigating it”, writes Palani Sundaramurthy, a Principal Program Manager Lead on Developer & Partner Services at Microsoft. “We have tracked this issue to our submission workflow incorrectly signing certain apps. [We need] to re-process the impacted apps in order to alleviate the problem. While we have already re-processed a few apps, […] we’re working to ensure that every impacted app is fixed.”

In the meantime, your only option is to wait this out. Apps are getting repackaged, resigned, and pushed out as fast as possible. App developers looking for a possible shortcut, however, can submit an update with a version number bump.

We’ll update this post when the fix is complete.

    <p>The <span style="color: rgb(0, 0, 0);">Principal Program Manager Lead on Developer &amp; Partner Services at Microsoft has only learned to say </span>“We are sorry” “ We are sorry” “We are sorry”.</p><p><br></p><p>How about them rehiring that QA team they fired long time ago to save costs so that they can actually test their updates before releasing them?

      <blockquote><em><a href="#319665">In reply to Maktaba:</a></em></blockquote><p>They could fund the QA team through a subscription to Windows 10. Windows 10 is free…. but you want QA? Haha! Try purchasing "Windows Live Quality Essentials 365, for Consumers". </p><p>Only $89/year for three computers.</p>

    <p>A functioning App Store is critical to fixing one of the great problems with computers – viruses. It makes purchasing software safe and easy. Microsoft is right to work hard to make a functioning store now. Their mistakes were 1) when Steam showed everyone how great a App Store was ignoring it 2) hobbling the store to only contain Universal apps instread if allowing everything that could run – x86, Android, web apps. Anything safe should be in the store. It failed to increase use of universal apps and created a store with bothering anyone wanted. This is egg on their face, I hope they do not abondon the Store as they have Groove Music, windows phone, Zune, Windows RT, and as it appears Cortana. That being said I rarely use the Windows Store now, but I pray it will get better! For it leads regular users to a safer, happier computing future.</p>

      <blockquote><em><a href="#319767">In reply to Angusmatheson:</a></em></blockquote><p>Exactly. Your comment nails it.</p><p>If MS would finally wake up and allow any (checked off course) x86/win 32 app/game into the store that would actually give it a chance to become appealing.</p><p>And that would be what would give UWP apps a chance, too if they have any left, because it would entice way more people to browse the store and hence then maybe also get the odd UWP app in between (if it is any good)</p>
