How to Prevent Cached Microsoft 365 User Details on Shared PCs
Question details
Users need to stop Microsoft 365 from displaying previous users' names and profile pictures after signing out on a shared computer.
- Product
- Microsoft 365
- Device & OS
- Windows
- Scenario
- Using Microsoft 365 accounts on a shared Windows PC via web browsers like Chrome or Firefox.
- Observed behavior
- Browser or Windows account caching causes the previous Microsoft 365 user's display name or profile picture to remain visible even after they have signed out.
Ensure you have saved all active work and completely signed out of your current Microsoft 365 session before adjusting browser or system profile settings.
Create Separate Windows User Accounts
This is the most secure method to ensure complete isolation of Microsoft 365 sessions, cached identity details, and user content.
By setting up distinct Windows user profiles, each person gets an independent environment. This prevents browsers and system caches from mixing credentials or displaying stale information from other users.
Click the Start button and select the Settings gear icon, or press Windows Key + I on your keyboard.
Click on 'Accounts' and then select 'Family & other users' from the left-hand sidebar.
Click on 'Add someone else to this PC' and follow the on-screen instructions to create a new profile.
Have each user sign in to their respective Windows profile from the lock screen before accessing Microsoft 365.
Use Separate Browser Profiles
If creating separate Windows accounts is not an option, you can isolate cached data by creating individual profiles within your web browser.
Disconnect Work or School Accounts
Remove account identities joined to Windows to stop the system from automatically suggesting previous Microsoft 365 users.
Try WPS Office for a Private, Local Document Experience
If you are concerned about shared browser caching and stale account details, consider switching to WPS Office. As a powerful, lightweight, and free alternative to Microsoft Office, WPS allows you to manage files locally on your computer with a highly familiar interface, completely bypassing web-based caching issues.
Frequently Asked Questions
Why does my Microsoft 365 profile picture stay on the login screen?
This occurs because web browsers cache images, cookies, and identity details to speed up future logins. Additionally, if you selected 'Allow my organization to manage my device', your work or school account may be saved directly to the shared Windows profile.
Does clearing browsing history remove Microsoft 365 cached details?
Clearing browsing history alone is usually not enough. You must specifically clear 'Cookies and other site data' as well as 'Cached images and files' in your browser settings to completely wipe the stored Microsoft 365 session details.
Can I use Guest mode or Incognito to prevent caching on shared PCs?
Yes. Using a Guest profile or an Incognito/InPrivate browsing window is an effective temporary solution. Once you close the Guest or Private window, all session data, cookies, and cached Microsoft 365 details are automatically discarded by the browser.
