Dear Nancy Letshabang,
To enable user switching in Windows 11, please ensure that additional user accounts are properly created and activated. You can do this by navigating to Settings > Accounts > Other users, then selecting Add account to create new work profiles. If the accounts already exist but are not appearing, open the Run dialog (Windows + R), type lusrmgr.msc, and verify that the user accounts are enabled under Local Users and Groups.
Additionally, confirm that Fast User Switching is enabled in the registry by setting the HideFastUserSwitching value to 0 under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System.
If administrative access is no longer available, we recommend contacting your IT administrator or using recovery options to regain control of the device.
If my answer is useful for you, please give it a vote.
Best regards,
Quinnie Quoc.
