Well, one time a few years ago, I bought a Windows RT tablet to my grandma so she can do her stuff with Microsoft Word and go on Internet and stuff. Don't need the Pro version, I thought.
Well, guess, what, I was wrong. I have almost nothing installed on it and, with time and updates, Windows ate all of the measly 32 GB of storage installed on it. It went highly unstable, with nothing you can uninstall or delete to fix it. So my grandma sent it back to me in hopes I could fix it and do something interesting. I did a lot of stuff on it before, and they mostly all failed so far, or I didn't had time to investigate deeper. And anyway, it should have run out of support as of now. So, this is the update log thread.
Well obviously, we can do some hacks to unlock whatever feature to get a bit more control, unlock Secure Boot or something, or something of that ilk. But first, we can try to disable BitLocker, which isn't something you can do on those. It's actually required so these hacks would go smoothly without fear it would turn it into a brick.This article
suggests Microsoft patched a vulnerability disabling a backdoor into Secure Boot. And from a look of it, this update looks installed. They still provide a good command to disable BitLocker:
manage-bde -protectors C: -disable
Invalid namespace, they say. Looks like the WMI namespace got somehow deleted. Let's reinstall it.
Oh, it worked. Let's try the manage-bde
one again... Also worked.
And it's unlocked. Next a reboot for good measure, and it should theorically be disarmed. Somehow. I'm not sure.
Next step would probably to reinstall it with the recovery partition, possibly downgrade it, unless someone have a better idea. To be continued...
On that note, thanks @gameblabla
