NVIDIA driver loses POPCNT support, causing BSODs on Microsoft Windows 11, Microsoft Windows 10

Microsoft Windows 11’s upcoming model updates (24H2) gained’t help processors with out POPCNT instruction. But now NVIDIA has shocked customers by asserting the top of life help for CPUs that don’t help POPCNT. Starting with Release 555, unsupported Microsoft Windows 10/11 PCs will encounter BSODs should you set up this driver model.

The driver will set up superb, however once you restart your PC, it should search for POPCNT and, if lacking, BSODs galore. So, you need to not updates to the show driver model 555 or larger to keep away from this problem. Or, you’ll have to make use of the recovery surroundings to take away the motive force or reinstall the OS after which set up an older model of the show driver.

NVIDIA highlighted the change in its official bulletins publish, which instructs on checking whether or not your CPU helps POPCNT. It recommends a command-line software named Coreinfo to test if the precise instruction set is current. The software didn’t work for and stored closing immediately.

There are different instruments, similar to CPU-Z and WhyNotWinAI, to test it. You may even use the official processor specs web page by Intel or AMD to find out about it.

POPCNT got here into the limelight after Microsoft’s system necessities for Microsoft Windows 11 24H2 surfaced. The Redmond large hasn’t clarified about ditching the older CPUs with out this instruction set, however many OS options gained’t work with out it in 24H2.

The instruction set started showing in processors nearly 16 years back, and meaning an enormous chunk of Microsoft Windows 10 customers gained’t be affected by this problem.

However, NVIDIA GPU customers who earlier ran Microsoft Windows 10 with a CPU with out this instruction set are actually in for a disappointment.

Microsoft Windows 11 24H2 POPCNT isn’t bypassable

When Microsoft Windows 11 launched, its pesky system necessities hindered many from putting in it. Gradually, workarounds appeared which allowed us to put in the OS, and even Microsoft printed an official bypass methodology. But with 24H2, the CPU requirement will get more problematic.

When you start the Microsoft Windows 11 24H2 set up, the setup will test in case your CPU helps the precise instruction set. If not, you can’t proceed the set up. In that case, you’ll have to follow the older variations of Microsoft Windows 11 (21H2, 22H2, and 23H2), which don’t implement this rule.

That being mentioned, the POPCNT requirement solely guidelines out very previous {hardware} that’s unqualified to help Microsoft Windows 11 options. The AI push is getting stronger with 24H2, infusing Copilot into unimaginable areas of the OS.
