Home windows 11: Microsoft stands agency on {hardware} necessities

Weeks forward of the official launch of Home windows 11, Microsoft right this moment introduced minor adjustments to the minimal system necessities for its new working system. Homeowners of comparatively current PCs working seventh Gen Intel Core CPUs or first-generation AMD Zen CPUs who had been hoping for a partial reprieve ought to put together to be upset. 

In an unsigned publish on the Home windows Insider weblog, the corporate introduced that it’ll make “a small variety of additions to the suitable processor record … however in any other case will preserve the minimal system necessities as initially set.” 

Additionally: Microsoft leaves a loophole for these desirous to run Home windows 11 on ‘unsupported’ {hardware}

The corporate additionally mentioned it is releasing a brand new model of its compatibility checker for members of the Home windows Insider Program and can make that software usually out there “within the coming weeks”: 

As we speak, we’re releasing an up to date preview model of the PC Well being Examine app [download] to Home windows Insiders. This up to date model expands the eligibility test performance with extra full and improved messaging on eligibility and hyperlinks to related assist articles that embody potential remediation steps … As we speak, we’re additionally concurrently releasing variations that assist 64-bit Home windows, 32-bit Home windows, Home windows on Arm and Home windows 10 in S mode PCs to Home windows Insiders. Home windows Insiders can present suggestions on the PC Well being Examine app by going to Suggestions Hub > Apps > PC Well being Examine.   

Credit score: Microsoft

The core necessities to run Home windows 11 are unchanged from those who had been revealed as a part of the unique announcement: A PC will want a minimal of 4GB of reminiscence and 64GB of storage; UEFI safe boot should be enabled; the graphics card should be suitable with DirectX 12 or later, with a WDDM driver; and a Trusted Platform Module (TPM) should be included. 

As for these additions to the suitable processor record, the record is certainly quick. Two households of server- and workstation-class Intel processors at the moment are on the record: the Core X-Collection and the Xeon W-series. The one mainstream Intel CPU added to the record is bound to boost eyebrows: Intel’s Core 7820HQ additionally occurs to be the CPU that ships with Microsoft’s expensive Floor Studio 2.

The record of supported AMD processors did not change. Microsoft mentioned it “rigorously [analyzed] the primary technology of AMD Zen processors in partnership with AMD” and concluded that none of these CPUs deserved to be added to the supported CPU record. 

Within the the rest of the lengthy (practically 2000 phrases) weblog publish, the Home windows staff reiterated the rules it is counting on to justify the brand new system necessities. Imposing the stricter requirements, they argue, will make Home windows 11 PCs extra dependable and safer than their predecessors, along with being extra suitable with fashionable purposes. 

When it comes to reliability, Microsoft says its telemetry makes a robust case for the brand new requirements. “Units that don’t meet the minimal system necessities had 52% extra kernel mode crashes,” the corporate reported. “Whereas units that do meet the minimal system necessities had a 99.8% crash free expertise.” 

That is a curious change in scales there. Changing these two statistics to a standard scale means that the older PC designs, absent different points, ought to nonetheless have a virtually 99.7% “crash free expertise.” 

Microsoft is on extra strong floor in terms of the safety argument. The TPM requirement, for instance, helps hardware-based authentication and in addition permits safe storage of Bitlocker disk encryption keys. The UEFI Safe Boot requirement has already been a part of the Home windows PC necessities since 2013 and is efficient at blocking pre-boot ransomware assaults reminiscent of NotPetya.  

Newer CPUs are designed to assist virtualization-based safety features that stop dynamic code injection into the Home windows kernel and in addition improve the safety of kernel-level drivers. “America Division of Protection (DoD) requires virtualization-based safety on Home windows 10 for his or her units,” Microsoft argues. “Whereas we aren’t requiring VBS when upgrading to Home windows 11, we consider the safety advantages it provides are so essential that we needed the minimal system necessities to make sure that each PC working Home windows 11 can meet the identical safety the DoD depends on.” 

The unstated piece of the CPU puzzle right here is the vulnerability of older CPUs to safety exploits collectively generally known as Spectre and Meltdown. Though Intel and Microsoft have collectively shipped microcode updates and Home windows system-level patches that mitigate the affect of these exploits, there is not any treatment, and the patches are recognized to have an effect on system efficiency. 

Microsoft says there is not any connection, nevertheless it’s a exceptional coincidence that the record of susceptible Intel CPUs consists of nearly all processors designed and offered in 2017 and early 2018 which can be unsupported on Home windows 11. As I famous on the time, “[W]hile software program patches can mitigate the results for now, the long-term answer entails basic adjustments to CPU design that would take years to achieve the market.” 

A January 3, 2018 bulletin from the safety consultants at CERT (a associate of the U.S. Division of Homeland Safety) was much more blunt: The one answer for Spectre/Meltdown assaults? “Exchange CPU {hardware}. The underlying vulnerability is primarily attributable to CPU structure design selections. Totally eradicating the vulnerability requires changing susceptible CPU {hardware}.” 

Almost 4 years later, it seems to be like Home windows 11 goes to play a serious position in that wholesale, wrenching alternative cycle. Anybody who intends to proceed utilizing older {hardware} will stay on Home windows 10, with that working system supported till October 2025.

What occurs after that’s anybody’s guess.
