Google Ships Native Gemini App for Windows, Targeting Copilot's Home Turf
On September 10, 2026, Google released a dedicated Gemini desktop application for Windows 10 and 11. This move places Google’s AI assistant directly onto Microsoft’s operating system, aiming to capture users who prefer a standalone interface over browser-based access. The app utilizes an Alt+Space shortcut for quick invocation, mimicking the convenience of Copilot’s existing integrations. However, initial reviews highlight a significant "OS integration gap," noting that the new app lacks deep taskbar hooks and Intune management support compared to the deeply embedded Microsoft Copilot experience.

Enterprise Survey Reveals 90% of Firms Fear Copilot Security Risks
A recent survey by Syskit highlighted in German tech media indicates that 90% of enterprises are concerned about security errors and permission misconfigurations when integrating Microsoft 365 Copilot. As organizations move from pilot phases to full-scale rollouts, the complexity of managing data access rights for AI agents has become a primary bottleneck. This fear is driving demand for stricter governance frameworks and specialized consulting to manage "Shadow AI" risks within the Microsoft ecosystem.

Pricing Clarity Emerges: Copilot Business at $21, Enterprise at $30
New pricing analyses confirm that as of September 2026, Microsoft 365 Copilot Business is priced at $21 per user/month (with an $18 promo for the first year), while the Enterprise SKU remains at $30. These costs are additive to existing Microsoft 365 licenses. In contrast, Google’s strategy continues to bundle Gemini features into Workspace plans starting at $7 per user/month, creating a distinct value proposition for cost-sensitive small and medium businesses.

Local view
In Germany, IT consultancy Pexon is promoting a structured 6-month pilot approach for M365 Copilot adoption, emphasizing the need to banish "Shadow AI" risks through rigorous governance before full deployment. Their guide suggests that strategic introduction is critical for avoiding the security pitfalls highlighted by recent surveys. Additionally, German media reports frame Google’s Windows app launch as a direct "challenge" to Copilot’s dominance, noting that while Gemini brings a persistent presence to the PC, it currently lacks the seamless OS-level integration that defines the Microsoft experience.
Context & numbers
- Seat Counts: Microsoft reports more than 20 million paid Copilot seats in use as of mid-2026, with third-party estimates suggesting ~33 million total active users across all surfaces including free tiers.
- Market Share: Over 90% of the Fortune 500 are reported to use Microsoft Copilot, leveraging the massive install base of 450+ million commercial Microsoft 365 seats.
- Pricing: Microsoft Copilot Enterprise pricing can effectively reach $69–$90 per seat when factoring in necessary prerequisite licenses and add-ons, despite the base $30 sticker price.
On the radar
- GitHub Copilot Billing Changes: GitHub announced upcoming changes to Copilot policies and billing, moving towards usage-based credits. Enterprises using GitHub Copilot alongside M365 Copilot should monitor these shifts for potential budget impacts.
- Excel Copilot Function Deprecation: Reports indicate Microsoft is phasing out specific "Copilot function" formulas in Excel in favor of the side-pane experience, signaling a consolidation of AI interfaces within Office apps.
