Enterprise IT

IT administrators have four days left on a deadline that affects millions of PCs. On October 13, 2026, Windows 11 version 24H2 in Home and Pro editions reaches end of updates, alongside Windows 10 Enterprise LTSB 2016 and Office 2021. After that date, those editions stop receiving Microsoft's monthly security and non-security updates.

Denmark has confirmed the largest data breach in its history. Hackers stole the contents of the country's Central Person Register — the central database of citizens' data — compromising records belonging to some 8 million citizens and residents, including people living abroad and the deceased.

The breach, disclosed on October 5, exposed names, addresses, Danish social security numbers, and other personal information. Danish minister Christina Egelund called it a "serious incident." The unauthorized access happened in September but was not discovered until October 2.
