Dear Peter,
Congratulations!!!!
Yours project is fully usable and produces perfect PE environment.
I can run NVDA and You have even incorporated not only USB audio drivers but also Oracle VM virtual box sound driver.
So i can try without USB flash disk because i do not know how to prepare bootable USB stick with resulted live image.
Unfortunately, Microsoft recenv.exe is designed for sighted users, so if I choose use system restore, Recenv will instruct me, that i must restart my computer, choose The operating system and then I would had to use system restore but without The possibility to get An feet back from The computer because in this mode, screen reader can not be used.
So my findings.
I do not have chance to use system restore even with Windows 8 or Windows 7 if system is corrupted so severely, that it will not enable boot to The standard Windows.
So blind users must use backup tool to create An system image because they can not use recovery tools to restore system from An previously created restore point if system is so severely corrupted, that only safe mode or even none Windows mode can be used to load it successfully.
It is The reality and there is no possibility except uses Microsoft recovery toolset, but this tool is coded so it can not be used from PE, because some pirates have put Hirens boot CD some years ago with Preinstalled ERD 2003, so powerful Winternals and Microsoft have done their est to disable users to run systemrestore.exe from The recovery toolset from PE environment.
But Peter, i know, that solving this is out of our possibility.
So.
1. You have prepared 100 % legal and very fast live project not only for sighted users.
2. Yours program is combining Java Access bridge with Festival voice feetback, so blind users can use Yours tool effectively, I will try it with Linux tomorrow to see, if Orca will be able to read data from edit box.
And i will accept The fact, that blind users will never be able to use all thinks like A sighted ones.
Yrs, i would had to use Android device with OCR capability to read screens and may be, that i would be even able to choose AN restore point from The calendar. It is not very comfortable, but it is very probably The only one possibility to solve some issues related to Windows and not only Windows OS.
2. I would had to buy special device, which transfers electronic analogue signal from monitor out connector on The graphics cart to The image, but this device costs some hundreds of US Dollars.
Then, I would had to use OCR to read some inaccessible screens.
It is inpossible to run system restore from An offline OS from live PE without using Microsoft recovery tool set, but toolset is incompatible with PE environment.
