MICROSOFT has just rolled out a fix for 74 security vulnerabilities and users should update now.

At least one of the security issues has been described as a ‘zero-day’, meaning it’s being actively exploited by cybercriminals.

根据 Krebs on Security, seven of the security problems have been rated “Critical” and a further 66 have been labelled as “Important.”

Only one of the problems was regarded as being low in its severity.

At least two of the vulnerabilities are said to be publicly known so hackers could exploit them if users don’t update.

The zero-day security issue is said to affect all supported versions of Windows.

It’s thought that around 1.4billion people use Microsoft Windows 10 和 11 each month.

Microsoft has revealed little information about the recently patched flaws so they can’t be exploited further.

If you’re a Windows 10 user most updates should download automatically.

To be on the safe side you can follow the steps below.
