Should I Turn Memory Integrity On?

Short Answer

Turning on Memory Integrity can strengthen your system’s protection against sophisticated attacks, but it may also cause compatibility issues with older drivers or reduce performance on low‑end PCs. Consider your hardware age, the software you rely on, and whether you need the extra security before enabling it.

When It Makes Sense

  • Good fit: You run a modern Windows 10/11 PC with up‑to‑date hardware and use the device primarily for everyday tasks like web browsing, email, and productivity apps. In this scenario, Memory Integrity adds a robust layer of protection with minimal impact.
  • Good fit: You handle sensitive data at work or personally—such as financial records, proprietary code, or confidential communications—and your organization recommends or mandates advanced Windows security features. Enabling Memory Integrity helps meet compliance requirements.

When You Should Avoid It

  • Warning sign: Your computer relies on older third‑party drivers (e.g., legacy printers, specialized cameras, or older gaming peripherals) that are not signed or have not been updated for virtualization‑based security. Memory Integrity may block these devices, causing loss of functionality.
  • Warning sign: You are using a low‑end system with limited CPU or RAM, and you notice noticeable performance degradation after enabling the feature. In such cases, the trade‑off may outweigh the security gain.

Pros and Cons

Pros

  • Provides hardware‑level isolation for kernel memory, making it significantly harder for malware to tamper with core system processes.
  • Helps meet security standards and corporate policies that require virtualization‑based security (VBS) features.

Cons

  • Can prevent older, unsigned drivers from loading, leading to device incompatibility issues.
  • May introduce a small performance hit, especially on CPUs without built‑in hypervisor support or on systems with limited memory.

Decision Checklist

  • Are all your essential hardware drivers compatible with Memory Integrity (check Windows Update or manufacturer sites for signed drivers)?
  • Does your system meet the recommended hardware specs for virtualization‑based security (modern CPU, TPM 2.0, at least 8 GB RAM)?
  • Can you tolerate a potential minor slowdown in exchange for stronger protection against kernel‑level threats?

Alternatives to Consider

If driver compatibility or performance is a concern, you can start by enabling other Windows security layers such as Controlled Folder Access, Windows Defender Application Guard, or regular BIOS/UEFI firmware updates. Another option is to keep Memory Integrity off while using a reputable anti‑malware suite and ensuring all software stays patched.

Final Recommendation

For most users with up‑to‑date hardware and a need for strong security, turning Memory Integrity on is advisable. However, if you depend on legacy drivers or experience measurable performance loss, weigh those factors carefully and consider testing the feature on a non‑critical system first. When in doubt, consult your IT department or a qualified security professional before making the change.

FAQ

Should I Turn Memory Integrity On?

If your PC runs modern, signed drivers and you value extra protection against sophisticated attacks, enabling Memory Integrity is generally beneficial. If you experience driver conflicts or performance issues, assess alternatives first.

What should I consider before I Turn Memory Integrity On?

Check driver compatibility, verify that your hardware supports VBS (TPM 2.0, recent CPU), and evaluate any potential performance impact. Testing on a non‑critical system can help you decide.
