The Windows 11 operating system update will soon roll out for PCs that would meet a set of hardware requirements to be able to install Windows 11. So now you can install Windows 11 on older PCs as well, which is a huge relief for individuals who own older PCs.
However, if you have an older PC, you will not be able to upgrade from Windows 10 to Windows 11 simply by pressing the update button. You will, however, be able to get an ISO file of Windows 11 and manually install it on your old computer. Businesses can test Windows 11 on older PCs as a stopgap measure until finances are available to purchase new systems with Windows 11.
A cautionary note: the performance of Windows 11 on older PCs cannot be guaranteed.
Back in June, Microsoft had released the minimum system requirements for Windows 11 which included the following: RAM: 4GB; Storage: 64GB; Processor: 1GHz 64-bit dual-core processor; UEFI compatibility; Secure Boot and TPM 2.0 support; 9-inch monitor with a resolution of at least 1366 by 768 pixels; DirectX 12 compliant graphics or WWDM 2.x support
There will be no 32-bit version of Windows 11 because it now only supports 64-bit processors. 32-bit apps and software, on the other hand, will continue to function normally.
