Disconnect Obsolete Accounts in Windows Settings and Re-sign in
Remove any conflicting work or school accounts from your Windows settings to prevent login issues when switching to a personal account.
Windows often stores work and school credentials globally. To successfully switch your Office apps to a personal account, you must first sever the connection to your old organization in your system settings.
Press the Windows key + I to open Settings. Go to "Accounts", then click on "Email & accounts".
Navigate to the "Access work or school" tab. Locate your old school or company accounts in the list, select the account, and click "Disconnect" or "Remove".
Open any Office application such as Word or Excel. Go to "File" > "Account" (or "Office Account"), locate the user information section, and click "Sign out" to remove the old credentials.
Ensure you have the correct Microsoft 365 Personal or Family edition installed. Click "Sign in" in the Office application and enter your personal Microsoft account details.
If the currently installed version of Office is an Enterprise or Education edition, it may not activate with a personal account. Uninstall it from the Control Panel and download the personal edition from your Microsoft account dashboard.

- 3. Open Your Office Files: Launch WPS Office and open your existing Microsoft files directly; no format conversion or complex account setup is required.

Frequently Asked Questions
Why does Windows keep prompting me to sign in to an old work account?
This happens because the work or school account is still linked in your Windows 'Access work or school' settings. You must manually disconnect it from the Windows Settings app to stop the recurring prompts.
Can I run my work Microsoft 365 and personal Microsoft 365 on the same computer?
Yes, you can add both accounts to Windows and switch between them within the Office apps. However, mixing Enterprise and Personal installations of the Office desktop applications can occasionally cause activation conflicts.
Will disconnecting my school account delete my personal files?
No, disconnecting an account from Windows only removes access to that organization's resources, network drives, and associated OneDrive. Your locally saved personal files on your hard drive will remain completely safe.
What should I do if my personal Microsoft 365 account won't activate?
Ensure you have completely signed out of any old accounts, disconnected them from Windows settings, and verified that the installed Office version matches your personal subscription. If you have an Enterprise edition installed, you will need to uninstall it and install the Personal edition.
