I feel your pain, I have nearly a dozen computers, counting laptops and desktops that don't meet the requirements. Only two of my computers, one desktop and one laptop do meet the requirements and have already been upgraded.
My choice of upgrading rather than replacing old stuff proved not to be so smart.
Microsoft had no choice. To keep pace with security these requirements must be met and to increase performance.
Many computers are deemed unfit for Windows 11 primarily due to
hardware requirements that weren't met by older devices. Here are some key reasons:
- TPM 2.0: Windows 11 requires a Trusted Platform Module (TPM) version 2.0, which is a security feature. Many older computers lack this chip.
- Secure Boot: This feature ensures that only trusted software can run during the boot process. Some older systems don't support it.
- Processor Compatibility: Windows 11 requires processors that support certain instruction sets, like SSE4.2. Older CPUs often don't meet these criteria. Intel credits feedback from developers as playing a significant role in the development of the instruction set.
- RAM and Storage: The minimum requirements for RAM and storage have increased, which means some older systems with less memory or storage capacity are not compatible. Usually, an easy fix if all other requirements are met.
Microsoft has provided ways to install Windows 11 on unsupported hardware, but it's not recommended due to potential issues with stability and updates.
Progress is painful and believe me, I'm going to be feeling it! Many of my Windows 10 computers are redundant, a few have not been turned on in months. But I will need to buy at least three new systems that can run Windows 11. Otherwise, I will risk letting the "bad guys" get into my network once Windows 10 is no longer supported.
FYI: My Brother all in one laser printer is over 12 years old and works perfectly with my Windows 11 desktop and laptop.
