How to Disable VBS and Speed Up Windows 11 or 10

Posted on

A security setting that’s on by default in Windows 11 and at least some installs of Windows 10 could be slowing performance in some by as much as 15 percent. Virtualization-based security, aka VBS, allows Windows to create a secure memory enclave that’s isolated from unsafe code. Another built-in feature called Hypervisor-Enforced Code Integrity (HVCI) uses the capabilities of VBS to prevent unsigned or questionable drivers and software from getting into memory. Together VBS and HVCI add a layer of protection that limits how much damage malware can do, even if it gets past your antivirus software. 

Unfortunately, VBS and HVCI have a significant performance cost, particularly when it comes to gaming. In our tests, we found that games ran as much as 15 percent slower with these settings on as with them off. This is true whether you’re using an old graphics card or even a speedy RTX 4090. It used to be the case that simply upgrading from Windows 10 to 11 would not enable VBS, but lately we’ve seen it get turned on after updates so you should not assume that it’s disabled on your system, even if you had it turned off before.
