The Easiest Windows Security Upgrade Hiding in Settings
If you’re like most Turlock residents we help at our Geer Road shop, you probably think upgrading your computer’s security means buying antivirus software or calling in an expert. The truth is, Microsoft built one of the most powerful security features right into Windows—and most people never turn it on. This easiest Windows security upgrade takes about five minutes and costs absolutely nothing.
What Is This Hidden Security Feature?
The feature we’re talking about is Memory Integrity, also called Core Isolation. It’s part of Windows Security that’s been available since Windows 10, but Microsoft doesn’t enable it by default on most systems.
Memory Integrity uses virtualization-based security to create an isolated environment that protects your computer’s most critical processes. Think of it as a vault inside your computer that hackers can’t easily break into, even if they manage to sneak malware onto your machine.
When enabled, this Windows security upgrade prevents malicious code from accessing high-security processes like your login credentials, encryption keys, and system files. It’s especially effective against sophisticated attacks that try to inject code into your computer’s memory.
Why Isn't It Already Turned On?
Great question, and one we hear often at our Turlock shop. Microsoft doesn’t enable Memory Integrity by default because it requires specific hardware features (virtualization support) and can occasionally conflict with older drivers or software.
Many computers sold in the Central Valley—especially budget models or machines a few years old—might have compatibility issues with certain hardware drivers. Microsoft plays it safe by leaving the feature off to avoid potential glitches after Windows updates.
That said, most computers built after 2018 handle Memory Integrity without any problems. We’ve enabled it on hundreds of systems right here in Turlock without issues.
- Modern processors include built-in support.Intel chips from 7th generation onward and AMD Ryzen processors all support the necessary virtualization features.
- Driver conflicts are rare now.Hardware manufacturers have updated most drivers since 2020 to work seamlessly with Memory Integrity.
- Older gaming peripherals may need updates.Some RGB lighting controllers and specialized gaming mice from 2017-2019 might require driver updates first.
How to Enable Memory Integrity Step by Step
Enabling this Windows security upgrade takes just a few minutes. You don’t need any technical expertise—just follow these simple steps on your Windows 10 or 11 computer.
- Open Windows SecurityClick the Start menu and type “Windows Security” then press Enter. You can also find it by clicking the shield icon in your system tray.
- Navigate to Device SecurityIn the Windows Security window, click on “Device security” in the left sidebar. This opens the hardware protection settings.
- Access Core Isolation DetailsUnder “Core isolation,” click the “Core isolation details” link. This opens a new page showing Memory Integrity settings.
- Toggle Memory Integrity OnClick the toggle switch next to “Memory Integrity” to turn it on. The switch should turn blue when enabled.
- Restart Your ComputerWindows will prompt you to restart. Save your work and reboot to activate the protection. The feature will be fully functional after restart.
What If You Get an Error?
Sometimes when you try to enable Memory Integrity, Windows will show a warning about incompatible drivers. Don’t panic—this is actually helpful information that tells you exactly what needs updating.
When you see the “Incompatible drivers” message, click on “Review incompatible drivers” to see a list. Windows shows the specific driver names and the hardware they control.
- Update through Device Manager.Right-click Start, choose Device Manager, find the device with the old driver, right-click it, and select “Update driver.”
- Download from manufacturer websites.For graphics cards, printers, or specialty hardware, visit the manufacturer’s support page for the latest driver versions.
- Check Windows Update first.Run Windows Update completely before attempting to enable Memory Integrity—many driver updates come through automatically.
In rare cases, you might have hardware that simply won’t work with Memory Integrity enabled. We’ve seen this with a few older fingerprint readers and some specialized business equipment here in Turlock. If you need that hardware to function, you’ll have to choose between the device and this security feature.
Will This Slow Down Your Computer?
This is the most common concern we hear at our Turlock repair shop, and it’s a fair question. Any security feature uses some system resources, but Memory Integrity is remarkably efficient on modern hardware.
For most everyday tasks—web browsing, email, Office applications, and video streaming—you won’t notice any performance difference at all. Microsoft designed this feature to operate in the background without impacting your experience.
Gaming and intensive applications might see a tiny performance impact, typically 1-3% in benchmarks. In real-world use, that’s essentially unnoticeable. We’ve enabled it on gaming PCs throughout the Central Valley without a single complaint about performance.
Other Easy Security Settings Worth Checking
While you’re in Windows Security improving your protection, there are a few other quick wins worth checking. These complement your Memory Integrity upgrade and take just minutes to verify.
- Enable Ransomware Protection.Under “Virus & threat protection,” turn on Controlled Folder Access to protect your documents from ransomware encryption attacks.
- Check Firewall Status.In “Firewall & network protection,” ensure your firewall is on for all network types—domain, private, and public networks.
- Review App & Browser Control.Under this section, enable SmartScreen for apps and files to get warnings about potentially dangerous downloads.
- Set Up Automatic Scanning.Schedule regular quick scans in “Virus & threat protection” to catch threats early without manual intervention.
Together, these settings create multiple layers of defense that work automatically once configured. It’s the security equivalent of locking your doors and setting your alarm—simple habits that make a real difference.
If you’d like a complete security checkup that goes beyond these basics, you can book an appointment online and we’ll review your entire system for vulnerabilities, outdated software, and other risks specific to your situation.

Frequently asked questions
Will enabling Memory Integrity cause problems with my programs?
For most modern software, no. Memory Integrity works seamlessly with standard applications like Microsoft Office, web browsers, and most games. Occasionally, older drivers for peripherals like printers or specialized hardware may need updating first. Windows will tell you if there’s a conflict before the feature activates, so you can address it safely.
Is Memory Integrity the same as antivirus software?
No, they serve different purposes and work together. Memory Integrity protects your computer’s core memory from tampering, preventing certain types of advanced attacks. Antivirus software scans files and monitors behavior to catch known malware. You should use both—Windows Defender (built-in antivirus) plus Memory Integrity gives you strong layered protection without buying additional software.
Can I turn off Memory Integrity if I need to?
Absolutely. You can disable Memory Integrity anytime by going back to the same Windows Security settings and toggling it off. Some situations—like installing certain hardware drivers or running specific legacy software—might temporarily require disabling it. Just remember to turn it back on afterward to maintain your protection.
How do I know if Memory Integrity is actually working?
After restarting your computer, go back to Windows Security > Device Security > Core isolation details. If the Memory Integrity toggle is blue and switched on, it’s active and protecting your system. You won’t see constant notifications or pop-ups—it works silently in the background, which is exactly what good security should do.
