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

You  need  to  turn  on  secure  boot

I am eligible for windows 11  installation. However, when  I  go  to  insider  program  there  is  written  that  updates  for  windows  10 . What  do  I  do  I  have   switched  to  beta  channel

It's a BIOS setting that's not turned on. Either Safe Boot and/or PTT on Intel fTPM for AMD. I had the same issue as you, but I turned those setting on, and now I'm fully compatible.

A common statement today seems to be " PC Health Check failed my machine"  and there are a lot of them with descriptions of capabilities that clearly match up with the required ones.  Hopefully Microsoft is following all the entries (a lot !) and will review their materials for accuracy and perhaps explain what makes all these systems fail the test.  

It is true that a large number of the computers represented have  1. Enough compute cores.  2. Enough memory .   3 . Large enough storage. and in quite a few the users have established that they have TPM.   

It's not quite that simple and it would be helpful if Microsoft can explain where they drew the line and why.  

We also know that there are people who installed Windows 11 before launch successfully.  Not much info on what devices that they used - new or not.   

The way it appears in the writeup. It is possible that the early builds that were based on Win10 might present us with 'some ' Win 11 features and allow it to be installed in current equipment.  However, at time of release it looks like those builds prior to release that are on non-qualified equipment will not be allowed to continue without upgrade or replacement.  This is just a guess judging by the way the writeup was made.

Recommendations :  Keep learning more about your system specifications and have them handy.  Learn about TPM and review your manufacturer website for Bios updates and drivers.   PC builders with empty TPM sockets on their motherboards are already ordering the modules online to make that happen.   Microsoft has been busy working on that PC Health Check app and we need to check for any updates that will help better identify compatibility.  There have been some great links and tips showing up on Community and there will be more to share in the days ahead.   Please do submit a Feedback to Feedback Hub if you have any issues with the function of  PC Health check and any suggestions to make it better or more understandable.  You can make Windows much better this way.

Take your time to prepare.  What you learn at this point will make it easier for the next steps because you will know the right questions to ask.

Better indications with this check than the MS one...

Thank you very much. It doesn't even need installation - runs in place.
