most recent windows 11 update is wiping SSDs
there's been multiple reports of people's computers not booting properly after the windows 11 24H2 KB5063878 update due to it essentially wiping the hard drives (specifically SSDs) on computers and laptops. users have reported their SSDs aren't able to be read/recognized and unable to be seen in bios settings either.

it's safe to assume all SSDs can be potentially affected by this update, so if you haven't updated yet turn off autoupdates
the bug caused by this update is seemingly triggered by installing/moving/deleting large files (50+ gb), which as simmers is what a lot of us do very pften
if you're unsure what windows version you currently have:
go to settings > system > about (at they very bottom) > and scroll down to see the current OS version
if you do currently have windows 11 24H2:
in settings, click 'Windows update' > 'Update history' > and under 'Quality Updates' check to see if the KB5063878 update is in the list of recently installed updates
don't panic, you can uninstall this update!
while in 'Update History', scroll to the very bottom and click 'Uninstall updates', and click 'Uninstall' for 'Security Update for Microsoft Windows (KB5063878)'
from there, give it some time to remove the update and after pause updates for as long as possible (5 weeks is the longest i think), but it will force an update if there's a big/official update for the fix
if you've already been affected and your computer is not starting or giving errors regarding your hard drive, i recommend visiting small pc repair shops to try data recovery as some have reported placing their SSD in an enclosure seems to work to recover the data
hopefully this is helpful is any kind of way! friendly reminder to back up your data to an external drive routinely!
