Windows 10 has 1,903 active CVEs compared to 652 on Windows 11, indicating a 2.9 times higher vulnerability. About 14% of Windows 10 users receive Extended Security Updates, leaving 2% on unsupported versions. HP reports that 30% of its installed base still uses Windows 10, reflecting a core group resistant to upgrading. Microsoft states that Windows is active on 1.6 billion PCs globally, with a noted 7% decrease in Windows OEM revenue attributed to lower PC demand and the end-of-support effects for Windows 10.

Which Windows 11 Update Is Causing Problems in 2026? – TheZeroNet

KB5094126, released in June 2026, is causing significant issues for Windows 11 users, including BSODs, boot failures, BitLocker lockouts, and problems launching Office applications. This update has particularly affected HP enterprise hardware, leading to BitLocker recovery loops and black screens. The issues stem from disk space limitations related to Secure Boot certificate handling and restricted EFI partition space. Affected users are advised to locate their BitLocker recovery keys and consider workarounds, such as launching Office applications directly. Windows 10 users are also experiencing similar problems due to the related update KB5094127. Microsoft is expected to release fixes in subsequent updates, including KB5101650 in July 2026.

Windows 10 LTSC 2021 has five months before security updates cost extra

Microsoft has announced that support for Windows 10 Enterprise LTSC 2021 will end on January 12, 2027, coinciding with the release of a final security update.
