All Windows 11 users should install the KB5029263 update as soon as possible
Microsoft has released a large new cumulative update for Windows 11 in the form of the KB5029263 update.
As this release fixes a series of security issues in the operating system, everyone running Windows 11 22H2 should install it as soon as possible. KB5029263 is a mandatory update so it will be installed automatically -- eventually -- but it is important enough to justify taking manual action to ensure you have it immediately.
