Check whether your computer can be upgraded to Windows 11 using Win11SysCheck
Is your computer up to the task of running Windows 11? To help you to find out, Microsoft released the PC Health Check app, updated it to make it more useful, but then pulled it for not being useful enough.
So how can you check your system's compatibility with Windows 11 -- especially the TPM requirement? We've already written about WhyNotWin11 which does a great job, but you can also try Win11SysCheck, a great open source utility that gives you a straight yes or no, along with helpful information if the answer is negative.
