The process of upgrading Windows operating systems was straightforward until Windows 11, which introduced a new requirement for a Trusted Platform Module (TPM), potentially rendering many capable PCs obsolete. The TPM is used for boot validation and storing biometric data, but it complicates data recovery and may lock out legitimate users. Users have found ways to bypass Windows 11's TPM and CPU restrictions, allowing installation on unsupported hardware. Microsoft’s enforcement of these requirements remains uncertain, raising concerns about system reliability and user access to updates. Many users are opting to stay on Windows 10 while advocating for continued support from developers.
