Microsoft will ship Windows 11 to the public on October 5, 2021. Eligible devices with compatible motherboards and CPUs will get the operating system via Windows Update, while incompatible devices will stay with Windows 10 (or move to Windows 11 using clean installation). A survey from Lansweeper reveals that quite a large chunk of professional computers and workstations are not ready to upgrade to Windows 11. In fact, more than 55% of surveyed PCs will not get Windows 11 via Windows Update.
Lansweeper analyzed more than 30 million computers in 60,000+ organizations around the world. 44.4% of tested computers pass the CPU compatibility test, which means those devices are running Intel 8th gen CPUs or 2nd gen AMD Ryzen CPUs or better. 91.05% passed the Windows 11 RAM compatibility test (4GB or more), and 52.55% of the checked computers have Trusted Platform Module 2.0 in a proper configuration. 19% of computers work without TPM, and 28% either use old Trusted Platform Modules or work with TPM off by default.
Remember that Windows 11 flags even the latest computers as incompatible if they work with disabled TPM. To fix that issue, manufacturers are now releasing BIOS updates that automatically configure firmware to receive Windows 11.
As for virtual machines, things are even less optimistic. While 44.9% have compatible CPUs and 66.4% utilize enough RAM to run Windows 11, only 0.23% of surveyed virtual machines have TPM 2.0. Professional virtualization software allows TPM passthrough (Oracle is also working on bringing this capability to its VirtualBox), but the study reveals companies rarely use it.
Microsoft allows users to check their PCs for Windows 11 compatibility using the PC Health Check tool. The utility recently received an update, and it can now provide a clear explanation on why a computer might not receive Windows 11 via Windows Update. For example, it can tell the user that the hardware is compatible, but the firmware requires hanging a few settings. Besides, Windows Update in Windows 10 will soon be able to check the system for compatibility with the newest OS.
