Hello,
Thank you for posting in Q&A forum.
You should unlink any devices you no longer use, because you can only download Microsoft Store apps and content to 10 devices attached to your account. If you can't download content from the Microsoft Store, you may have reached your device limit.
To unlink a device to free up downloads:
Sign in with your Microsoft account at account.microsoft.com/devices/content
Find the device you want to remove and select Unlink
Review your device details and select Unlink.
To remove a PC because you don’t own or use it anymore:
- Sign in with your Microsoft account at account.microsoft.com/devices
- Find the device you want to remove and select Remove device.
- Check the box to confirm removal, and select Remove.
I hope the information above is helpful.
Best regards
Zunhui
