Microsoft has released the August 2026 security updates for supported versions of Windows. Microsoft recommends that users and organisations install the updates promptly.
What businesses should do
For managed environments, updates should still be deployed in a controlled way: confirm backups, monitor known issues, test important line-of-business applications where appropriate, and then roll the security updates out across supported devices.
Home and small-business users can check Settings → Windows Update and install available updates. Managed KPTech clients should follow their normal patch-management process.
There has been understandable confusion around the Windows 11 version numbers appearing in 2026. Microsoft’s official release information states that Windows 11 version 26H1 is scoped to support new devices that came to market in early 2026.
Importantly, Microsoft says 26H1 is not designed as a feature update for existing devices and is not offered as an in-place update from Windows 11 24H2 or 25H2.
What this means
If your existing business PC is on a supported version of Windows 11, there is no need to hunt for a 26H1 upgrade. Continue using Windows Update and your normal managed update process.
Microsoft has published guidance for organisations preparing for Windows 11 version 26H2, the next annual feature update for Windows 11. Microsoft describes the release as continuing a predictable, low-disruption servicing approach.
What businesses should do now
There is no need to rush. Businesses should identify critical applications, confirm device readiness, keep current Windows 11 systems patched and use a staged rollout when 26H2 reaches general availability for their environment.
If you rely on specialist accounting, medical, engineering or industry software, application compatibility should be part of the upgrade plan rather than an afterthought.
Microsoft continues to develop Microsoft 365 Copilot across desktop, web and mobile. The July 2026 update included new push notifications in the Microsoft 365 Copilot mobile app, designed to help users catch up on relevant work items on iOS and Android.
What this means for businesses
Copilot is increasingly becoming part of the normal Microsoft 365 experience rather than a separate AI tool. That makes licensing, data access, staff training, information governance and security configuration increasingly important.
Businesses considering Copilot should first make sure Microsoft 365 permissions and document access are sensible. AI can only be as well governed as the information environment it is allowed to search.
