Microsoft has had six years to prepare for the launch of Windows 11, but the company is still struggling to explain its new hardware requirements. Windows 11 will officially support Intel 8th Gen Coffee Lake or Zen 2 CPUs and up, leaving behind millions of PCs that were sold during the launch of Windows 10. It’s an unusual surprise if you purchased a new PC for Windows 10, or perhaps you have a perfectly capable machine that’s even older. Windows 11 will require Intel 8th Gen Coffee Lake or Zen 2 CPUs and up, TPM 2.0 (Trusted Platform Module) support, 4GB of RAM, and 64GB of storage. Microsoft doesn’t typically enforce such specific processor requirements with Windows — with both Windows 8 and Windows 10 only requiring a 1GHz processor, 1GB of RAM (2GB for 64-bit), and 16GB of storage (20GB for 64-bit). Power users of Windows, and IT admins alike, have built up an expectation of being able to upgrade to the latest OS, regardless of what hardware they’re running. It looks like that’s about to end with Windows 11. After much confusion last week, Microsoft attempted to explain its hardware requirements again yesterday, and it sounds like the main driver behind these changes is security. Coupled with Microsoft’s hardware requirements is a push to enable a more modern BIOS (UEFI) that supports features like Secure Boot and TPM 2.0 (Trusted Platform Module). When you combine TPM with some of the virtualization technologies that Microsoft uses in Windows, there’s an understandable security benefit that we’ve discussed in detail previously. Microsoft claims that a combination of Windows Hello, Device Encryption, virtualization-based security, hypervisor-protected code integrity (HVCI), and Secure Boot “has been shown to reduce malware by 60 percent.” You obviously need modern hardware to enable all these protections, and Microsoft has been building toward this moment for years. TPM support has been a requirement for OEMs to gain Windows certification since around the release of Windows 10, but Microsoft hasn’t forced businesses or consumers to enable it. Microsoft’s decision to force Windows 11 users into TPM, Secure Boot, and more comes at a pivotal moment for Windows. It’s Microsoft’s operating system that’s always caught up in ransomware and malware attacks, and things are only going to get worse if the level of Windows hardware security doesn’t go up a notch. That delicate balance of security and the typical openness of Windows is something that Microsoft will struggle with over the next decade, as it wrestles with modernizing Windows and the understandable backlash. While Microsoft is waiving its new hardware requirements during the preview phase of Windows 11, we still don’t know exactly what devices will be supported when it launches later this year. Microsoft tried to offer some more clarity around this yesterday, but it wasn’t the level of detail we were hoping for. “As we release to Windows Insiders and partner with our OEMs, we will test to identify devices running on Intel 7th generation and AMD Zen 1 that may meet our principles,” says a blog post from the Windows team. That could be good news for the Surface Studio 2, a $3,499 device that Microsoft still sells with a 7th Gen chip that’s not on the Windows 11 list. This same blog post also revealed that the 7th Gen is probably as far back as Microsoft is willing to concede. “We also know that devices running on Intel 6th generation and AMD pre-Zen will not” meet Microsoft’s minimum system requirements, said the blog post before it was edited to remove this line. It’s not clear why Intel’s 6th Gen chips are definitely off the list, but part of this decision could be related to Spectre and Meltdown — two major computer processor security bugs that affected nearly every device made for 20 years.
