Hello jamie younkin,

Welcome to Microsoft Q&A forum.

Please understand that our forum is a public platform, and we will modify your question to cover your personal information in the description. Please notice to hide these personal or organization information next time you post error or some information to protect personal data.

Both the errors you see point to an update failed because the update target is currently in use. Before we proceed further, may I know if you have encounter this in any specific context?

I'm waiting for your reply.

Error 0x80073D02 means “The package could not be installed because resources it modifies are currently in use.” This occurs when Windows tries to register or update an MSIX/AppX package (like Microsoft.WindowsAppRuntime) while some of its files or dependent components are still running.

To handle it when it happens again:

1. Close apps that may use Windows App Runtime
   • Close all open apps, especially Store apps and any app recently updated via Microsoft Store.
   • Sign out of the current user session and sign back in, then let Windows sit idle for a few minutes so background updates can retry.
2. Reboot and let updates complete
   • Restart the PC normally (not Fast Startup resume if possible).
   • After sign-in, wait a few minutes connected to the internet so Windows Update and the Store can finish pending app registrations.
3. Retry the update or app install
   • If this error appeared during a Windows Update or Store app update, run the same update again after the reboot.
4. If it keeps recurring
   • Check Event Viewer → Applications and Services Logs → Microsoft → Windows → AppxDeployment-Server for repeated 0x80073D02 entries to confirm it’s only a transient registration failure.
   • As long as apps and Windows work normally, this error can often be treated as a transient condition that resolves after a reboot and retry.

The error code itself is documented as a deployment failure due to resources in use, not a permanent corruption.
