Far far as I can tell it's on MS server side, hopefully I can raise it with MS. Below is written by CP under my instructions.
✅ Moderator Notice – Ongoing Microsoft Store Update Issue (Error 0x8000000B)
Posted for visibility to all users experiencing this problem.
We are currently seeing multiple reports of Microsoft Store failing to update with error 0x8000000B (and occasionally 0x80070057) across both Windows 10 and Windows 11. This includes:
- Fresh installations of Windows
- Systems with no pending Windows Updates
- Users who have not modified or customized their devices
- Reports from several regions and languages
- Identical symptoms appearing within the same 24–48 hour period
Because this issue also occurs on clean installs before any cumulative updates are applied, the evidence strongly suggests this is not a device‑specific problem. Instead, it appears related to the Microsoft Store package or one of its dependency packages currently being delivered from Microsoft’s servers.
This type of issue cannot be resolved through local troubleshooting alone.
Common steps such as:
- Resetting the Store
- Re‑registering the Store
- Running wsreset
- Changing region or network
- Reinstalling Windows
…will not resolve the problem at this time, as they all rely on the same backend Store package that is currently failing validation.
🔧 About unofficial workarounds
Some users have posted methods involving manually downloading dependency packages from third‑party file hosts and installing them via PowerShell. While these may work temporarily, they are not supported or recommended, as they:
- Use files from non‑Microsoft sources
- Bypass normal package validation
- May cause future Store updates to fail
- Are not safe to recommend on Microsoft Q&A
🟦 Current Status
This issue will require a backend fix from Microsoft.
Historically, similar Store‑package issues are corrected silently once the affected package or dependency metadata is republished.
Once corrected, the Store will update normally again without any action required from users.
📌 What you should do
At this time, the best approach is simply to wait for Microsoft to update the Store package on their servers. No local repair steps are needed.
This notice will be updated if additional official information becomes available.
