Preparing for Insider Preview Builds of Windows 11 - ***UPDATED 6/28***

Hey, are you  sure  your PC  doesnt  support  TPM?

Just  check  the  BIOS and  enable  it  if  you have  the option, gor  amd  its  called  rtpm  and  can  only  be  found  in advanced  mode  :)

After reading and seeing the despair some users are having with Win 11 upgrade hardware reqs, here are some ideas to help. TPM 2.0 - TPM 2.0 will be a req for the 1st round of Insider Dev channel builds, starting next week. However, TPM 1.2 will be the soft req as time moves towards Win 11 RTM.If your having issues with TPM, try looking in your Bios Settings for either Intel PTT or AMD fTPM depending on your CPU. CPU reqs - The latest docs on Microsoft Hardware requirements list 8th gen Intel CPU's or higher, and 2nd Gen Ryzen CPU's as a minimum.

However, older CPUs that meet at least the following Supports 2 Processor Cores• Compatible with the x64 or ARM64 instruction set• Supports PF_ARM_V81_ATOMIC_INSTRUCTIONS_AVAILABLE instruction set (for ARM64 processor)• Supports PAE, NX and SSE4.1• Supports CMPXCHG16b, LAHF/SAHF, and PrefetchW• Meets the supported processor generation listThen older CPU's should work but Windows Update will warn you that it doesn't recommend installing Win 11 with those CPU'sThe 1st version of the PC Health Check app is bugged and one of the devs posted on Twitter that they know, and will hopefully be releasing an updated version even possibly today at some point, fingers crossed that the hardware detection software is improved, along with reasons on a line by line basis as to what fails to be compatible with Win 11https://twitter.com/dispensa/status/1408226015260790787?s=20A lot of time will go by from the 1st Insider build to RTM, so things will change as we get closer to RTM, and hopefully, Microsoft will do a better job of communicating Win 11 requirements and rationale for these requirements. Until the 1st ISO is released and people have a chance to try installing on systems that according to Microsoft don't make the cut, we won't know too much.I have a certain build installed and running on a 1st Gen Surface Pro, and it seems to run fine, Insider setting warns me that I don't meet the required hardware and it remains to be seen if I will get the update to the 1st Insider build on that hardware.Microsoft obviously didn't prepare for the reveal of Win 11, and Info is slow to be released by MS, but hopefully, this will improve with time.Hope this helps.

CPU Generation is Soft Floor,Hard Floor is all meet

Try  enabling  it  for the  OS, if  you  enter  tpm.msc  in  run  tab, you can  see  if  you  enabled  it  or not,  there  is  usually  2 options  related  to  tpm, turn Them on  both, hope  this  could help  a  bit  :)

Why?
