Malware includes viruses, worms, adware, spyware, and ransomware — they all work differently but tend to cause similar problems on your PC.

The best way to stay safe from potential bugs or security threats that could arise on out of date Windows 11 software is to update to the latest version. If you are running 23H2, you should be able to head to your PC’s settings and update to 24H2, a free update for all Windows 11 users.

Microsoft has released Windows 11 KB5066835 and KB5066793 cumulative updates for versions 25H2/24H2 and 23H2 to fix security vulnerabilities and issues.

People living in the European Economic Area will get it for free by registering. For other users to get it for free, they need to have updated to the latest version of Windows 10, have a Microsoft account and backed up their PC settings. Otherwise, you have to pay a $30 (£22) fee or use 1,000 Microsoft Rewards points to access ESU.

Time has finally run out for Microsoft users reluctant to upgrade to Windows 11, but you have a few options if your computer doesn't meet the requirements.
