As the deadline approaches for Windows 10’s lifespan, users are being cautioned about the discontinuation of support. The latest cumulative update, version KB5066791, addresses multiple zero-day vulnerabilities, including severe issues like privilege escalation, secure boot bypass, and memory corruption.

This update signifies the final opportunity for security patches unless users opt for the Extended Security Updates, which come at a cost and limited device eligibility. Microsoft indicates that most Windows 10 users will no longer receive these essential updates, making an upgrade to Windows 11 prudent.

The implications of zero-day exploits being discovered and made functional before fixes are issued highlight the critical need for timely updates to maintain system security. As observed:

‘Zero-day means these exploits were discovered and exploitable before there was a fix released for them.’

For those who are still hesitant, it’s advisable to back up data and consider transitioning to the latest operating system, even if it may seem a daunting task.
