Blocking Unwanted App or Malware Installation on Windows 10 PC

Preventing unwanted app, malware, or other potentially unwanted program installations on your Windows 10 PC is crucial for maintaining your system's security. Here's a step-by-step guide on how to block such installations:

Using Windows Security Features:

Click on the "Start" button to open the Start Menu.

Select "Settings" (the gear icon) to open the Windows Settings.

In the Windows Settings window, click on "Update & Security."

In the left sidebar, choose "Windows Security."

Click on "App & browser control."

Under "Check apps and files," select "Block (recommended)."

This setting enhances your system's defense against unwanted app installations and potential malware.

Using Group Policy Editor:

Press "Win + R" to open the Run dialog.

Type "gpedit.msc" and press "Enter" to open the Group Policy Editor.

In the Group Policy Editor window, navigate to "Computer Configuration" > "Administrative Templates" > "Windows Components" > "Windows Installer."

In the right pane, double-click on "Prevent Windows Installer from generating system restore points."

Choose "Enabled" and click "Apply."

This policy prevents Windows Installer from creating system restore points before installing applications.

Next, navigate to "Computer Configuration" > "Administrative Templates" > "System" > "Don't run specified Windows applications."

Double-click on "Don't run specified Windows applications" and select "Enabled."

Click on the "Show" button and add the applications you want to block by entering their file names (e.g., app.exe). Click "OK" to confirm.

This policy prevents the specified applications from running.

After configuring these policies, unwanted app installations should be blocked, and system changes are limited.

These steps help enhance the security of your Windows 10 PC by blocking unwanted app installations and potential malware threats. It's important to maintain your system's security settings and regularly update your antivirus software for effective protection.
