Hi Fred,
The codes 8007000E and 80860010 often appear when Windows encounters a corrupted sign-in component or damaged authentication cache, not necessarily a lack of physical memory. Even though the first code points to a “memory error,” in most cases it actually means that Windows can’t properly load the Microsoft Account Sign-in service or one of its background processes has missing or outdated data.
Over time or after major updates or resets the system’s Microsoft AAD Broker Plugin or Sign-in Assistant can fail to refresh stored credentials. This prevents your device from verifying your Microsoft account correctly, which then causes the loop of sign-in failures and alternating error codes.
Try these steps
Reset the Sign-in Cache
Sign out of your Microsoft account on the PC.
Open File Explorer and navigate to:
C:\Users<YourUserName>\AppData\Local\Packages
Find and delete the folder:
Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy
Restart the computer and sign back in.
This rebuilds your local Microsoft authentication data.
Repair System Files Open Command Prompt (Admin) and run these commands one by one:
DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow
Restart your PC after both finish. These commands scan and repair system files that can interfere with account sign-ins.
Ensure Services Are Running Press Win + R, type services.msc, and make sure these are Running and set to Automatic:
Microsoft Account Sign-in Assistant
Windows Update
Cryptographic Services Restart them if they’re stopped.
Test with a New Local Account Create a temporary local user, then link it to your Microsoft account. If this works, the issue lies in your original profile’s registry or cache and you can migrate your files safely afterward.
If the same problem continues even on a new profile, it might be linked to an outdated Windows build or an authentication mismatch with Microsoft’s servers. In that case, I recommend checking for optional updates or reaching out to Microsoft Support so they can refresh the account token from their end.
Let me know how it goes, Happy to help!
