word doc history deletion

Remove unwanted Word entries with Word → File → Open, right-click each document, and select Remove from list; then secure the Microsoft account if another person may be able to sign in.

Remove Word’s recent-document history

• Remove one document: Open Word → File → Open, right-click the document, and select Remove from list.
• Clear most of the list: Under File → Open, right-click an entry, select Clear unpinned Documents, and select Yes.
• Stop displaying recent documents: Open File → Options → Advanced → Display, then set Show this number of Recent Documents to 0. ^1^

Choose Remove from list, not Delete file. Removing an entry only hides the shortcut; deleting the file removes the actual document.

Hide recent files from Start and the taskbar

The list that appears when selecting the Microsoft/Start logo or right-clicking an app is separate from Word’s list.

In Windows 11:

1. Open Start → Settings → Personalization → Start.
2. Turn off Show recently opened items in Start, Jump Lists, and File Explorer. ^2^

This hides recent-item shortcuts in those Windows locations but does not delete the underlying documents.

Delete private Outlook.com messages

Check both Sent Items and any folders containing the conversation:

1. Select the messages and choose Delete.
2. Open Deleted Items and select Empty folder.
3. To remove the remaining recoverable copies, open Deleted Items, select Recover items deleted from this folder, and then select Empty folder.

The last step is permanent and cannot be undone. ^3^

Deleting your copy does not delete copies already delivered to another person.

Protect the account from secret sign-ins

Deleting histories is not sufficient if somebody can access the account.

1. Review the Microsoft account Recent activity page. It shows sign-ins from the previous 30 days, including available device, application, and location details.
2. For an unfamiliar entry under Unusual activity, expand it and select This wasn’t me.
3. Change the account password and update its security information. ^4^
4. In the Microsoft account security dashboard, open Advanced security options, scroll to Sign out everywhere, and select Sign out. This can take up to 24 hours and signs the account out of browsers and applications, except Xbox consoles. ^5^
5. Turn on two-step verification so a password alone is insufficient for a new sign-in.

Also lock the computer whenever leaving it unattended by pressing Windows key + L.
