Just recently have been getting this error code and I'm not sure why. I've gone into command and reset, wuauserv. Reinstalled it in the registry and rebooted my computer multiple times. I've ran the built in Windows Troubleshooter tool (Which was absolutely useless and wasted my time). This happens when trying to download/install anything from the Microsoft Store app, and also throws the same code when I try to check for updates on my computer. I'm not sure what else to try. Thanks for any and all help. I've posted a screenshot of the error message from Microsoft Store and Windows Updater and they're the same exact error code.
