Hi, this is Henry. I'd like to share some insights regarding the issue. Apologies that I can't respond in your native language, but I’ve translated the content to better understand the context.
Based on your description, I recommend trying the following solution.
- Go to the Main Microsoft Account Devices Page:
- Do not use the Store page. Instead, go directly to this link on your browser: https://account.microsoft.com/devices
- Sign in with the same Microsoft account.
- Find and Remove the Device:
- You will see a list of all devices linked to your account.
- Find the device you want to remove.
- Click on "Show details" or "Manage" for that device.
- On the next screen, find the "Remove this device" or "Unlink" option (it may be under a "More actions" menu).
This page is the master list for your account and is usually more effective than the Store-specific page.
Hope this helps.
