Hi Peter Spray,
I can understand your confusion. Microsoft account can be used in several places, but not every password works the same way, and the storage warning does seem alarming. I will address each of the requests below:
For your first question: Your storage
- Go to https://account.microsoft.com/storage
- Sign in with your Microsoft account
- You’ll see a breakdown such as:
- OneDrive files
- Photos and videos
- Email and attachments
If OneDrive backup is enabled on your Surface, common folders like Desktop, Documents, and Pictures are synced and count toward that storage. To check this on the Surface itself:
- Click the OneDrive icon in the Taskbar tray
- Click Settings icon > go to Sync and backup
- You can review which folders are backed up.
For your second question: Your password
If you sign in to your Surface with a Microsoft account, then the password is the same. However, you need to actually look at what the prompt asks for: it’s typically for your Surface to actually request a PIN or Windows Hello (face/fingerprint) instead. If Windows says your account password instead of PIN, it is the same with your Microsoft account.
The 80% warning is likely about cloud storage, usually OneDrive or Outlook. Check those locations first to delete unessessary files that are taking up your space.
