According to Lansweeper research, 43% of PCs still cannot install Windows 11 due to hardware criteria known as Trusted Platform Module (TPM) set by Microsoft for the operating system, which leaves many users hooked on Windows 10.
Many PCs, even fairly modern ones lack a TPM, and many PCs are left behind when migrating to Windows 11, according to Lansweeper. It is possible to get around this limitation, but it is not an appropriate option and possibly not a long-term one.
“Specifically, only 57.26% of CPUs for workstations tested met the system requirements for upgrading to Windows 11, while 42.74% did not. And, while the majority passed the RAM test (92.85%), about 65% of the workstation TPMs tested met the requirements, while over 15% failed and 20% was not TPM compatible or did not have it enabled,” Lansweeper said.
It also found that 42.76 percent of the estimated 27 million PCs tested in 60,000 organizations failed the CPU test, better than the 57.26 percent failure rate in the previous test a year ago. Overall, 71.5 percent of PCs failed the RAM test and 14.66 percent failed the TPM test.
Microsoft has also admitted that administrators trying to deploy new hardware and apply a Windows 11 update may run into a brick wall, lending credibility to those who are cautious.
