One in six Windows PCs still runs Windows 10, and the vulnerabilities are piling up

Approximately 17% of all Windows client devices are still running Windows 10, equating to about one in six machines. Windows 11 accounts for 78% of Windows devices, with third-party trackers indicating it surpassed 70% of desktop share as of February 2026. Official support for Windows 10 ended in October 2025, but Microsoft’s Extended Security Updates (ESU) program will provide patches until October 2027 for eligible devices. A typical Windows 10 device has an average of 1,903 active security vulnerabilities, nearly three times the 652 CVE-tracked flaws found on a Windows 11 machine. 66% of Windows 10 vulnerabilities are classified as "high" or "critical." Small and medium enterprises have 21.4% of their Windows devices still on Windows 10, while larger enterprises have 16.6%. The healthcare and pharmaceuticals sectors have 23% of devices on Windows 10, followed by consumer and retail at 22%, and manufacturing at 18%. Lansweeper is urging organizations to enroll in the ESU program and address reasons for remaining on Windows 10 as 2026 approaches.

Microsoft confirms WSUS service degradation impacting all versions of Windows

A significant issue has emerged with the Windows Server Update Service (WSUS), affecting all versions of Windows client and server. Microsoft acknowledged the service degradation that began before July 14, coinciding with the latest Patch Tuesday. This degradation has caused prolonged synchronization times and occasional timeouts during sync operations on WSUS servers, attributed to a buildup of publishing metadata. Microsoft is working on a resolution to improve performance and restore synchronization times. The affected platforms include various versions of Windows 11, Windows 10, and Windows Server from 2012 to 2025. An update is expected to be released shortly to address the issue.

Windows 11 gets new registry policy to give IT admins more control

Microsoft will introduce a new registry policy in Windows 11 in July 2026 that allows IT administrators to enable automatic acceptance of single sign-on (SSO) prompts on managed devices. This policy will streamline user authentication by using Windows sign-in credentials automatically for Microsoft apps or services, reducing the need for manual authentication. The registry path for this policy is HKLMSOFTWAREPoliciesMicrosoftWindowsAAD, with the value AutoAcceptSsoPermission (DWORD) set to 1. It can be deployed using Group Policy Objects (GPO), Intune, Microsoft Configuration Manager, or mobile device management (MDM) tools. This setting is applicable only to Windows 11 versions 25H2 and 24H2 that have received the July 2026 Patch Tuesday updates (KB5101650 and KB5094126) and is designed for managed devices using Entra ID accounts, not personal Microsoft accounts or unmanaged devices.

Microsoft says stop waiting to install Windows updates. Here’s why

Microsoft has revised its guidance on Windows updates, urging users to install them within three days due to the rise of AI-driven cyber threats. Jeremy Chapman from Microsoft 365 emphasized the need for timely updates, recommending a maximum deferral period of two days for quality updates. In June, Microsoft patched 206 vulnerabilities, highlighting the importance of these updates to avoid significant risks. AI can help attackers exploit vulnerabilities quickly, making the practice of delaying updates obsolete. Microsoft has also developed an AI tool, MDASH, to identify vulnerabilities in Windows code.

Microsoft demystifies how Windows updates work

Microsoft has released a guide on the Windows servicing model, detailing monthly security updates, optional preview releases, hotpatch updates, and feature rollout mechanisms. Patch Tuesday occurs every second Tuesday of the month, delivering cumulative security updates to supported Windows versions. For consumers and small businesses, updates are managed through Windows Update, while enterprises can use various tools like Windows Autopatch and WSUS. Hotpatch updates, which focus on security fixes, can be installed without a restart, unlike quarterly baseline updates that require one. Optional non-security preview updates are released in the fourth week of each month for testing upcoming fixes and new features, available only for the latest supported Windows versions. Unmanaged devices can access these updates through Windows Update settings, while IT-managed devices depend on organizational policies. Microsoft also issues out-of-band updates to address urgent issues, which can be deployed through enterprise management tools. New features for Windows 11 are rolled out throughout the year via various channels, with a gradual rollout strategy to monitor quality and compatibility, using the Controlled Feature Rollout approach.
