Hi,
Thank you for sharing your question. I understand how confusing it can be when your account shows different device counts across the Microsoft Store and the devices page, especially when some entries appear blank or missing details.
This type of discrepancy can occur when certain devices are disabled, deleted, not fully registered, or have incomplete metadata, which prevents them from appearing correctly on the Microsoft account devices page. Microsoft Learn also notes that device synchronization delays or registration errors can cause devices to appear without names or not show up at all. In some cases, platform limits or backend sync issues can temporarily affect the accuracy of your device list.
To resolve this, ensure each device is signed in with the same Microsoft account, has device sync enabled, and is properly registered. If unnamed devices appear, they may not have completed the registration process, so signing out and back into the affected devices can help force a refresh. In some situations, sync delays may require up to 24 hours for the device page to update. If the issue involves metadata corruption or backend delays, Microsoft recommends reviewing device status in account settings and waiting for synchronization to complete.
Are the two unnamed devices ones you recently reset, reinstalled, or stopped using, or do you recall any changes that may have affected their registration?
Feel free to share what you find, and I’ll be happy to help you track down the remaining discrepancies or guide you through deeper troubleshooting if needed.
I hope this helps.
Best Regards,
Noel
