Windows has a pretty self-explanatory feature called Fast User Switching. It lets multiple users log into the same PC with different accounts. Obviously, they can’t all use the computer at the same time but when they log in, they’ll have their own desktop, preferences and so on. While it’s easy to disable Fast User Switching in Windows 10, let’s first discuss why you’d want to do that.
First of all, this feature is not a new one being available since Windows XP. When you have multiple user accounts logged in at the same time, Fast User Switching can negatively affect your computer’s performance.
How to disable Fast User Switching in Windows 10
To access the feature in Windows 10 Creators Update, click on the Start button and then once more on the avatar icon of the current user. The Switch account option or users that have previously logged in should be available in the menu.
1. Disable Fast User Switching via Group Policy Editor
Disabling this option is not difficult but to do it, those who are using Windows 10 Enterprise or Pro edition will need to open the Group Policy Editor.
To open it, click on the Start button and type “run” then open the app. In the Run text field type “gpedit.msc” without quotes and hit the OK button.
Not that you’ve opened the Group Policy Editor, go to the following location: Computer Configuration -> Administrative Templates -> System -> Logon.
Then, scroll in the right panel to locate the policy called “Hide entry points for Fast User Switching” and double-click it.
In the new window that opens, select the “Enabled” option to activate the policy then press OK. The change will be applied instantly. If you click on your user’s avatar in the Start menu there’s shouldn’t be any Switch option or other users that have previously logged into the system.
2. Disable Fast User Switching via registry
The Group Policy Editor is not available to those using Windows 10 Home edition, but they can still disable Fast User Switching by tweaking the registry.
Open the Run dialog (from the Start button’s right-click menu), type in “regedit” without quote marks and hit the OK button.
In the Registry editor go to the following location: HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
There, create a new DWORD32 key and name it HideFastUserSwitching if you don’t have it already. Set its value to 1.
From then on, Fast User Switching should be disabled and in order to switch to another user you would need to log off from the current one first.
