Man of Honour
I suppsoe that's the whole point of insider builds, if you opt in then you accept that stability or performance won't be optimum. This should not even be news really as it sets an incorrect perception.
Same, the OS works fine, but for productivity it is more awkward to use for no good reason.Win11 (alpha) is rock solid in my experience...my only bug bears (excuse the pun) are the UI changes that sometimes don't make sense (to me) and result in far more clicks to do what I used to be able to do blindfolded in win10.
Take your pick it is either incompetence or they want everyone having to run hardware which support TPM and that isn't for any reasons favourable to the end user...
If you have secure boot and TPM enabled then it should install and activate fine on a 6th gen PC. I did it recently and all that happened was a popup asked me to confirm that I'm running a CPU that is not supported. When I tried it without secure boot, the installer wouldn't start.It's not even just TPM...my 2ndary PC is an i5 6600k and can quite easily run win11, and the mobo has the correct version of TPM..but no... only 8th gen intel or later is supported.
