Yesterday arvo i abandoned my attempts to solve it by myself, given that lotsa research & experimenting over a couple of days had given no progress. Hence i contacted MS via their
link in Settings, & eventually a 2.x hour telecon & remote session ensued. Though very pleasant to deal with, & surprisingly focused on genuinely trying to solve the problem, MS Tech Support also could not get past the admin access impasse; all their magic tricks still implicitly relied on being able to get the elevated privileges. Ha!! They mentioned that the root cause might be that 1709 is not yet supported by VB 5.1.30... but i suspect that was a guess; my research did not unequivocally rule that in or out.
Once all her efforts to fix 1709 were just as unsuccessful as my own, eventually the tech attempted to download & clean-install a 1703 ISO. Guess what ?[anyone following this thread already knows the answer] - that [ie, the ISO getting & creating bit] was also blocked by the cursed UAC debacle. Ha, again. The call ended with her telling me that my choices now appeared to be:
Get myself to a "real" Windows m/c & repeat her procedure to create a 1703 ISO.
Contact VirtualBox & ask if they can release an update that's compatible with 1709 [ie, she continued with that theory].
Wait... & wait, &... for MS to eventually fix 1709 for VB compatibility, at which point it would be pushed to me via usual Windows Updates.
After the call was over, i glumly reviewed the command strings she'd attempted on my screen in the command box re getting the ISO, & realised she'd made two typos. I repeated the steps myself with the correct paths, & was pleasantly surprised to observe that now the 1703 ISO creation process initiated & ran... no error!! In time, it finished, still without error. Said ISO file was dutifully inserted in the VM's virtual optical drive with said VM then booted, & a normal 1703 installation process began... ran... finished... & succeeded. All my pgms are gone, of course [but no data was lost, as all that safely resides on my real SSD in my real OS... Linux natch], but now this clean 1703 is fully functional [just like it was before i made that regrettable decision a fortnight ago to allow the 1709 "upgrade"]. Today i'll repeat the process on my other [still broken] 1709 VM.
Thanks to all here who took an interest & tried to help.
@moveback Thanks for your quick reply. Sorry I am replying so late; because I've had several other problems with Windows 10 Version 1703. I subsequently ran Windows Reset and the malware as well as all of my installed apps were deleted. So, as of now the malware is gone; but I am going to do what you suggested and burn a CD of Malwarebytes just to prepare for any other possible malware.
hi, I tried your link but it can not open now, what's wrong? And several days ago, I downloaded a similar program that can download Utube video too, I wanna say your functions are really similar, so will you mind I compare you two? And I need some advice about operate the two
