How to Secure a Shared Windows Computer for Kids, Guests, and Public Use

Whether you're setting up a family computer, a guest PC, or a kiosk in a public space, securing a shared Windows computer is essential to protect your data, restrict misuse, and provide a safe experience for all users. Without proper precautions, a shared device can quickly become vulnerable to viruses, unauthorized access, or even accidental deletion of important files.

This guide walks you through practical steps to lock down and manage a shared Windows computer for different users: kids, guests, and public access.

1. Create Separate User Accounts

Avoid sharing one administrator account with everyone. Instead:

🔐 Use These Account Types:

Administrator: For you or the system owner only.
Standard User: For kids or guests.
Guest Account / Kiosk Mode: For public or extremely limited access.

🛠 How to Do It:

Go to Settings > Accounts > Family & other users.
Click Add account and select "I don't have this person's sign-in information" for local accounts.
Assign the correct user type (Standard or Child account).

2. Enable Parental Controls (For Kids)

Use Microsoft Family Safety to:

Set screen time limits.
Block inappropriate websites.
Monitor app usage.
Restrict game ratings by age.

🛠 Setup:

Go to Settings > Accounts > Family & other users.
Add your child’s Microsoft account.
Visit family.microsoft.com to configure restrictions.

3. Turn On Guest Account (For Temporary Use)

The legacy Guest account is no longer easily accessible, but you can simulate one:

🛠 Create a Restricted Local Account:

Open Command Prompt (Admin).

Run:

net user GuestUser /add  
net user GuestUser /active:yes  
net user GuestUser *    # (set a password or leave blank)  
net localgroup users GuestUser /add

Pro Tip: Use Group Policy Editor or Local Security Policy to further restrict GuestUser access.

4. Enable Kiosk Mode (For Public Use)

Kiosk Mode locks the PC to a single app or function (like a web browser or a learning app).

🛠 Setup Kiosk Mode:

Go to Settings > Accounts > Family & other users.
Click Set up a kiosk > Assigned access.
Choose an app (like Microsoft Edge) and assign a user.

Perfect for libraries, front desks, or displays.

5. Restrict Control Panel and Settings Access

Use Group Policy Editor (gpedit.msc) or Registry Editor to hide or lock system settings.

Hide Control Panel:

Run gpedit.msc.
Navigate to:
User Configuration > Administrative Templates > Control Panel
Enable: "Prohibit access to Control Panel and PC settings"

6. Use App Restrictions (Allow or Block Programs)

You can allow only specific apps to run for kids or guests.

🛠 With AppLocker (Windows Pro/Enterprise):

Run secpol.msc.
Go to Application Control Policies > AppLocker.
Create rules to allow or deny software execution.

For Windows Home users, consider third-party parental control apps or use Family Safety for Microsoft Store apps.

7. Disable USB Drives and File Transfers

Prevent users from copying data or infecting the system with USB drives.

🛠 Disable USB Ports:

Open Device Manager.
Find and disable USB Mass Storage drivers.

Or edit the registry to block USB ports entirely:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR]
"Start"=dword:00000004

8. Enable Automatic Updates and Antivirus

Ensure Windows Defender (or third-party antivirus) is active and set to auto-update.

🛡 Recommendations:

Turn on Real-time protection.
Schedule weekly scans.
Set Windows Update to install automatically.

9. Clear Browsing Data on Exit

For guests or public users, configure the browser to delete history, cookies, and sessions on exit.

In Microsoft Edge:

Go to Settings > Privacy, search, and services > Clear browsing data > Choose what to clear every time you close the browser.

10. Set Automatic Logout or Screen Timeout

Prevent users from leaving accounts signed in.

🛠 Enable Timeout:

Go to Settings > System > Power & sleep.
Set short screen and sleep times.

For shared environments, use Group Policy to force logoff after inactivity.

Bonus: Use Deep Freeze or System Restore Tools

Tools like Deep Freeze can revert the system to a clean state after every reboot — ideal for public access.

Final Thoughts

A shared Windows computer doesn’t have to mean a security nightmare. With the right mix of user accounts, parental controls, app restrictions, and smart usage policies, you can ensure the system stays safe, efficient, and user-friendly — no matter who logs in.
