Step 1: Open Windows Security

Warnings may indicate:
- Antivirus disabled

Antivirus protection is one of the most important security features.
To check it:

- Select Check for Updates
Install any available updates.
New malware appears constantly, making regular updates essential.
Step 5: Review Firewall Settings
The Windows Firewall helps block unauthorized access to your computer.
To check it:
- Return to the Windows Security dashboard
- Select Firewall & Network Protection
Verify that:
- Domain Network is protected
- Private Network is protected
- Public Network is protected
For most users, all available firewalls should remain enabled.
Step 6: Check App & Browser Control
App & Browser Control helps protect you from dangerous downloads, websites, and apps.
To review these settings:
- Open App & Browser Control
- Review available protection features
Look for settings related to:
- Reputation-based protection
- SmartScreen protection
- Potentially unwanted app blocking
These features help prevent unsafe software from running.
Step 7: Review Device Security
Device Security helps protect your computer at the hardware level.
To check it:
- Return to the Windows Security dashboard
- Select Device Security
Depending on your hardware, you may see:
- Secure Boot
- TPM (Trusted Platform Module)
- Core Isolation
- Memory Integrity
Modern security features can help protect against advanced attacks.
Do not worry if every option is not available, as support varies between systems.
Step 8: Verify Windows Updates Are Current
Many security vulnerabilities are fixed through Windows updates.
To check for updates:
- Open Settings
- Select Windows Update
- Click Check for Updates
Install all available:

Keeping Windows updated is one of the simplest ways to improve security.
Step 9: Review Account Security
Your Windows account plays an important role in overall security.
Check:
- Password strength
- Sign-in options
- Recovery information
- Two-factor authentication (if using a Microsoft account)
To review account settings:
- Open Settings
- Select Accounts
Strong passwords significantly reduce security risks.
Step 10: Check User Account Control (UAC)
User Account Control helps prevent unauthorized changes to your system.
To verify UAC settings:
- Search for User Account Control
- Select Change User Account Control Settings
For most users, the default recommended setting provides a good balance between security and convenience.
Avoid completely disabling UAC unless absolutely necessary.
Step 11: Review Installed Security Software
Many PCs come with additional security software installed.
Review:
- Antivirus programs
- VPN software
- Anti-malware tools
- Security suites
Make sure you:
- Keep them updated
- Remove software you no longer use
- Avoid running multiple antivirus programs simultaneously
Too many security tools can sometimes create conflicts.
Step 12: Run a Security Scan
After reviewing your settings, perform a scan to confirm everything is working properly.
To run a scan:
- Open Virus & Threat Protection
- Click Quick Scan
For a deeper inspection:
- Select Scan Options
- Choose Full Scan
Regular scans help identify threats before they become serious problems.
