As a zero-day security vulnerability posing significant risk to users is confirmed as under active exploitation—the DHS and Microsoft have urged millions to update now.

Microsoft launched Phone Link for Windows PCs last year. It allows Windows users to remotely access their iPhones to make phone calls, check notifications, send and receive iMessa

Microsoft updated its support page to warn users not to run Windows 11 on an unsupported PC, but the company also has official instructions on installing the operating system on devices that don't meet minimum requirements. Generally, that means PCs with a TPM 2.0 chip — a security chip required for Windows 11.

The confusion around Microsoft updates continues. Just as it releases the last Patch Tuesday of 2024, with a new zero-day amongst 71 vulnerabilities, it also warns 400 million users they risk losing access to future security fixes if they update their PCs.

Yesterday was the last Patch Tuesday of 2024, and with it Microsoft has provided a number of security updates, eliminating 71 security vulnerabilities across various Microsoft apps and services. Microsoft categorizes 16 of these vulnerabilities as “critical” and classifies all but one of the remaining issues as “high risk.

Microsoft just closed out its Patch Tuesday updates for 2024 by releasing fixes for 72 security flaws across its software portfolio: 17 rated Critical, 52 rated Important and one rated Moderate, and one that has been actively exploited in the wild.
