How to Create a Guest Account in Windows 10
Windows' guest account lets other people use your computer without being able to change PC settings, install apps or access your private files. That comes in handy when you have to share your computer temporarily. In Windows 10, you can no longer easily turn on the guest account from the Control Panel. Here's a workaround to enabling a guest account -- that actually works.
Across the web, you'll find articles that tell you how to enable the "hidden" guest account in Windows 10, using the Command Prompt or the group policy editor in Windows. While these methods do make it look like the guest account is enabled, they don't actually work. When you try to switch to the guest account, you'll be instead forced to log into your current account.
There is a method, however, that I've tried that does work, adapted from a tip offered by Super User member The Professional: Create a new user account and assign it to the guests group. This will make that account act the same way the built-in guest account should: The user will be able to use your computer without accessing settings or installing apps. Since "Guest" is a reserved account name in Windows, we'll use "Visitor."
1. Right-click on the Windows button and select Command Prompt (Admin). This is the quickest way to open the Command Prompt as an administrator.
2. Click Yes when asked if you want to continue.
3. Type the following command and then click Enter:
net user Visitor /add /active:yes
4. Press Enter twice when asked to set a password. This will create a blank password for the account.
5. Type the following command and then hit Enter:
net localgroup users Visitor /delete
This removes the Visitor user from the default users group.
6. Type the following command and then hit Enter:
net localgroup guests Visitor /add
This adds the Visitor user to the guests group, which is more restricted than local users.
That's all there is to it. You can now close the Command Prompt window.
How to Switch to the Guest Account
1. Click the Windows button.
2. Click on your username.
3. Click Visitor.
Alternatively, you can choose the Visitor account from the Windows login screen.
