When installing the update, some users are finding themselves faced with an 0x80070643 error, a generic failure message. Unfortunately, according to Microsoft, “because of an error in the error code handling routine,” this might not be the correct error. The actual error could be one related to the recovery partition not being large enough: “Windows Recovery Environment servicing failed. (CBS_E_INSUFFICIENT_DISK_SPACE).”
I love it.
I mean, not surprising - the amount of times I’ve had to reinstall the Windows Store via command line because it somehow broke is nothing short of surprising for an app meant to update/install other apps…
This is the best summary I could come up with:
The patch, released on January 9, was meant to address a vulnerability that allowed attackers to bypass BitLocker encryption by using the Windows Recovery Environment (WinRE).
It’s downhill from there as users are directed to fire off commands to disable the WinRE before deleting and recreating recovery partitions.
Microsoft has asked users encountering issues with disk space – which might be concealed by the erroneous install failure error 0x80070643 – to have a go at the procedure to manually resize the partition to deal with the problem.
A glance at social media shows that the problem is widespread, and users are reluctant to apply Microsoft’s workaround.
The Register contacted Microsoft to find out if the software giant intends to update its patch or push out something that does not require hacking away at the file system from the command line after a failure.
Showing an unhelpful error message and then requiring a user to delve into the world of the command line to fix things.
