The Patchwork Quilt of Despair

It seems Microsoft's solution to the CVE-2024-20666 BitLocker vulnerability is a bit like giving someone a Band-Aid for a broken arm – it's well-intentioned but not quite hitting the mark. The KB5034441 security update was supposed to be a hero, swooping in to save the day, but instead, it's causing 0x80070643 errors. Rather than giving users a straight-up "Hey, you need more disk space!" message, it’s throwing the cryptic 'ERRORINSTALLFAILURE' at them – because who doesn't love a good mystery?

DIY Partition Resizing: Not for the Faint of Hard Drive

And what's the solution offered? Essentially, an IT workout routine to bulk up your WinRE partition. Microsoft has kindly laid out the steps for this partition pump-up, but be warned – it’s not for the tech-averse. One wrong click and your data might be walking the plank. As a workaround, they've also released a PowerShell script that's sort of like a personal trainer for your WinRE partition, helping it get into shape to fend off BitLocker bullies.

Hide and Seek with Windows Update

After flexing your PowerShell muscles, you might want to play a game of hide and seek with the KB5034441 update using Microsoft's Show or Hide Tool. Why? To stop Windows Update from being overzealous and trying to install the update again, inevitably leading to the same error message that started this whole fiasco. It's like telling a persistent salesperson, "Thanks, but no thanks."

Backup or Bust

Last, but certainly not least, before you go on this tech adventure, back up your data. Because while resizing partitions can sometimes be as smooth as jazz, it can also go full heavy metal, leaving you with a hard drive that's about as useful as a chocolate teapot. So, unless you enjoy living on the edge (of data loss), let's keep those files safe, shall we?

Remember, cyber safety is no joke, but sometimes the hoops we have to jump through to achieve it can be a little... humorous.
