Update on Windows 11 minimum system requirements
The minimum requirements listed below have changed in a few main areas:
Firstly, the amount of RAM required has increased from 2GB to 4GB.
Secondly, whilst the clock speed of your CPU won’t need to be any higher, it will now need to have at least two cores and be 64-bit (32-bit is no longer an option). Some older CPUs that meet these requirements are unfortunately also no longer compatible with Windows 11 – you can see a full list of these here.
Thirdly, the amount of HDD space you will need at a minimum has increased from 16GB to 64GB, though Microsoft has stated that this may increase over time when updates are made to the operating system. The WePC recommendation is that you set aside 100GB on your hard drive.
Fourthly, and this is the thing which may catch the most people off guard, is that users will need to have both a processor that is fitted with a Trusted Platform Module (TPM) chip, of at least version 2.0. and a motherboard whose firmware supports a UEFI, Secure Boot capable BIOS. Both of these features are, in Microsoft’s view, crucial to boosting the security of your machine, which is something the company is putting increasing priority on with Windows 11. Users running on older CPUs, such as processors older than the Intel 8th Gen / AMD Zen 2 / Qualcomm 7 & 8 Series, will likely come across a ‘TPM 2.0 not found’ error, and those running on older motherboards may lack UEFI secure boot. You can read more about how to check if your motherboard has TPM support and how to enable it in our Windows 11: How To Enable TPM In Bios guide.
Finally, you will apparently only be able to run Windows 11 on a screen that has at least 720p resolution, that is of at least 9″ in size and has 8-bit color channels. For the vast majority of users, none of these should be a problem, unless you ar running off an especially old CRT monitor.
