Microsoft releases KB4598298 update to fix Windows 10 crashes and restart problems We might only be three weeks into 2021, but Microsoft has already issued a number of patches for Windows 10 -- and now it's time for another one. If you have been experiencing unexpected restarts in Windows 10, or crashes when using BitLocker, there's a new update for you to install. Microsoft has released the KB4598298 update to fix a number of issues including BitLocker-related crashes, and restarts caused by exception code 0xc0000005 (Access Violation) in LSASS.exe. Before you rush to grab the update, however, it's worth noting that there is a known issue relating to system and user certificates that you should be aware of.
