Check Settings → Accounts → Your info first: if your name shows Administrator, the Word-document error is file-specific; if it does not, an existing administrator must promote your account or Windows must be recovered.
1. Determine which permission is missing
Open Start → Settings → Accounts → Your info.
- Administrator appears under your name: Your Windows administrator rights are still present. Continue to section 2.
- Administrator does not appear: Your account is a standard user. Continue to section 3.
Windows documents this location as the way to identify whether the signed-in account is an administrator.^1^
Do not remove the second profile yet. It may be needed if it is the only administrator account.
2. If your account is already an administrator
The problem is likely limited to those documents or their folder, rather than your Windows account type.
- Close Word completely.
- Open Task Manager with Ctrl+Shift+Esc.
- Under Processes, end any remaining Microsoft Word or
WINWORD.EXEprocess. - Return to the document folder and try deleting the files again.
Word creates temporary owner files whose names begin with ~$. If Word is completely closed and such a file remains beside the affected document, delete the ~$... file first, then delete the document. Microsoft documents this procedure for files that remain locked by Word.^2^
If Windows instead identifies another account as the owner or says Access denied, do not grant “Everyone” full control. Check the folder:
- Right-click the folder containing the documents.
- Select Properties → Security → Advanced.
- Note the displayed Owner and whether your current username has Modify or Full control.
- If this is a OneDrive, network, work, or school folder, obtain permission from its owner or administrator rather than changing ownership.
The exact error text and document location are needed to distinguish an ownership problem from a locked, rights-managed, or network-hosted file.
3. If another administrator account still exists
Sign in to that administrator account, then promote the account you want to keep:
- Open Settings → Accounts → Other users.
- Expand the account you want to restore.
- Select Change account type.
- Choose Administrator, then select OK.
- Sign out and sign back into the restored account.
Creating another profile alone does not make it an administrator; its account type must be changed by an existing administrator.^3^
After confirming that the restored account shows Administrator, remove the unwanted profile:
- Copy any files needed from that profile first.
- Open Settings → Accounts → Other users.
- Expand the unwanted account.
- Next to Account and data, select Remove.
Removing it deletes that profile’s sign-in information and local data from this PC, but does not delete the person’s Microsoft account.^3^
4. If no account can approve an administrator prompt
If every account is standard and Windows requests administrator credentials that no account can supply, account-type changes cannot be completed normally. Use Reset this PC as the supported recovery fallback:
- Back up accessible personal files to external storage.
- Obtain the BitLocker recovery key first if device encryption is enabled.
- Hold Shift while selecting Power → Restart.
- In Windows Recovery Environment, select Troubleshoot → Reset this PC.
- Select Keep my files.
- Complete setup and create the administrator account when prompted.
Keep my files reinstalls Windows and preserves personal files, but removes installed applications and settings. A reset can still involve data loss, so back up first.^4^ Microsoft lists Reset this PC as the most disruptive recovery option, after less invasive options have failed.^5^
