3 Windows Security Fixes to Stop Hackers
Passwords alone won't protect your PC — and if you're still depending only on them, you're leaving your computer exposed to ransomware, phishing attacks, and spyware. Here are three simple Windows security fixes that address the real threats and take just minutes to set up.
1 Block Ransomware with Controlled Folder Access
Ransomware doesn't need your password — it spreads through email links, infected websites, or malicious downloads, then encrypts your files before you realize what's happening. Controlled Folder Access is a built-in Windows feature that automatically blocks apps from changing files in your most sensitive folders like Documents, Pictures, and Desktop. To enable it, go to Settings > Privacy & Security > Virus & threat protection > Manage ransomware protection, then toggle on 'Controlled folder access.' If you use backup software or legitimate apps that need file access, you can whitelist them individually.
2 Replace Passwords with Windows Hello
Passwords are phishable — attackers trick you into typing them on fake websites, or keyloggers record them as you type. Windows Hello uses your fingerprint or face recognition to sign in instantly, and there's no password to steal. Your biometric data stays on your device, not on Microsoft's servers, so even if a website is hacked, your sign-in method is safe. Set it up in Settings > Accounts > Sign-in options, then add a fingerprint or face scan. You can keep a PIN as a backup if your device doesn't have biometric hardware.
3 Revoke Unnecessary App Permissions
Apps routinely request more permissions than they need — a calculator asking for your location, a flashlight app reading your contacts, or a notes app wanting access to your camera. Each excess permission is a window for data theft or spyware. Windows stores all permission grants in one place: Settings > Privacy & Security, where you'll see toggles for camera, microphone, location, files, and more. Disable access for any app that doesn't legitimately need it, and review this list once a quarter as new apps are installed.
These three changes — ransomware blocking, biometric sign-in, and permission auditing — close the three biggest holes in Windows security. None of them require technical expertise or expensive tools, and together they make your PC a much harder target for hackers.
