Written by Kathy Hajewski | Oct 23, 2026, 1:15:00 PM

Microsoft rolled out five licensing changes in the last month. They touch Copilot usage billing, CSP software pricing, Windows Server lifecycle planning and Windows 365 Business administration. Each one below comes with a recommended next step.

This month at a glance

Update	Status	What to do
Copilot Cowork usage-based billing	Available now	Set budgets and alerts before users get access. Pilot first.
Copilot Credit P3 and Microsoft Agent P3	Available now	Start on pay-as-you-go. Size a P3 once usage is predictable.
CSP software pricing: 5% uplift on monthly billing	Effective October 1, 2026	Check renewal dates on annual-term software billed monthly.
Windows Server 2016 end of support	January 12, 2027	Decide upgrade, ESU or migrate for every 2016 server.
Windows 365 Business: Deprovision now	Available now	Back up user files first. Add an approval step.

1. Copilot Cowork usage-based billing

Status: available now

Copilot Cowork is an agentic layer that sits on top of an existing Microsoft 365 Copilot seat. It completes complex, multi-step tasks across tools from start to finish: sending emails, updating documents, scheduling meetings. Microsoft meters Cowork separately from the Copilot seat, in Copilot Credits. Credits are a shared currency that also covers Copilot Studio agents, Work IQ APIs and other Copilot-family services.

Licensing prerequisite: each user must already hold a Microsoft 365 Copilot user subscription license (USL).
Billing unit: Copilot Credits at $0.01 each, pooled at the tenant level with other Copilot-family services.
What drives cost: the model (lighter models use fewer credits than higher-reasoning ones), runtime (the cloud orchestration that keeps a long task running), context (people, roles and signals pulled from mail, files, chats and meetings) and tools (each action Cowork takes).
Usage controls: spending policies in the Microsoft 365 admin center set credit limits and alerts at user, group or tenant scope, and the Cost Management dashboard shows who is using credits and which policy applies.

Estimated cost per task, from Microsoft's Copilot Credits licensing guide:

Task size	Credits	Approx. cost
Light: narrow context, light model, few tool calls	100 to 300	$1 to $3
Medium: richer context, capable model, several tool calls	300 to 700	$3 to $7
Heavy: broad context, high-quality model, many tool calls	more than 700	more than $7

Our take: because cost depends on how complex each task is, monthly spend per user can swing a lot. Microsoft calls these rough planning estimates, so treat them as a ballpark, not a forecast, and test your assumptions with a pilot group before a broad rollout. Set budgets and alerts before users get access so your admins hear early if consumption runs hot. One catch: a spending policy also controls access. Anyone inside the scope of a policy that selects Cowork can use it regardless of the credit limit, so restrict access through policy scope, not a low limit.

2. Copilot Credit P3 and Microsoft Agent P3 pre-purchase plans

Status: available now

Microsoft offers two pre-purchase plans (P3) for organizations that want to pre-fund Copilot Credit consumption, including Copilot Cowork, instead of paying as they go. Both are one-year, pay-up-front commitments bought at tiered discounts. They differ in which services the prepaid pool covers.

Copilot Credit P3: covers Copilot Credit usage, including Copilot Cowork and Copilot Studio agents.
Microsoft Agent P3: a broader pool that spans Copilot Credit usage plus services such as Microsoft Foundry and Microsoft Fabric.
Term: one year, paid up front. The more you buy, the bigger the discount.
Purchases are final: no cancellations or exchanges, and plans renew by default at the end of the term.
Pay-as-you-go alternative: billed monthly for credits used, with no up-front commitment.

Our take: if Copilot Cowork is your main workload, Copilot Credit P3 is the closer fit. If your agent work extends into Foundry or Fabric, Microsoft Agent P3 lets one prepaid pool flex across those services. Either way, start on pay-as-you-go, collect usage data, and size a P3 once your pattern is predictable. Purchases are final, so an oversized commitment is money lost.

3. CSP software pricing: 5% uplift on monthly billing

Status: effective October 1, 2026

Microsoft is applying a 5% cost-of-capital uplift to Cloud Solution Provider (CSP) software subscriptions with an annual-term commitment billed monthly. The uplift ties price to billing frequency. The licenses and entitlements don't change.

Affected products include SQL Server, Windows Server, Client Access Licenses (CALs) and System Center.
Annual-term subscriptions paid in full up front: no change.
Month-to-month subscriptions: no change.
Existing affected subscriptions pick up the uplift at renewal on or after October 1, 2026. No retroactive adjustment.

Our take: if you hold annual-term software subscriptions on monthly billing, check your renewal dates now. Switching to annual billing at renewal avoids the uplift. Staying monthly keeps cash-flow flexibility at a 5% premium. For example, $100,000 in eligible annual subscriptions costs about $5,000 more per year on monthly billing.

4. Windows Server 2016 end of support

Status: January 12, 2027

Extended support for Windows Server 2016 ends on January 12, 2027. After that date, Microsoft stops providing security updates and technical assistance. Extended Security Updates (ESU) are available now for organizations that need more time to finish an upgrade or migration.

ESU availability: through Azure Arc, and for purchase on CSP.
Pricing: ESU is licensed per core. Microsoft publishes current Azure Arc ESU rates on its Azure Arc pricing page.
Purchase sequence: each later ESU year requires buying all prior years first.
Your paths: upgrade to Windows Server 2025, enroll in ESU for more runway, or migrate workloads to Azure through the Azure Migration and Modernization Program.

Our take: with about three months left, decide which Windows Server 2016 servers you can upgrade before the deadline and which will need ESU. Because ESU years are bought in sequence, waiting doesn't avoid the year-one cost. Use ESU as a bridge for workloads with a set migration or upgrade date, not as an open-ended extension.

5. Windows 365 Business: Deprovision now

Status: available now

Windows 365 Business streams a full Cloud PC (apps, data and settings) to any device and is built for smaller organizations. When a license is removed or expires, the Cloud PC enters a seven-day grace period before it's deprovisioned. Microsoft added a Deprovision now option that lets admins end that grace period and release the license right away.

Default behavior: a removed or expired license still triggers the seven-day grace period unless an admin steps in.
Deprovision now: ends the grace period immediately and frees the license for reassignment.
Data impact: deprovisioning permanently deletes the Cloud PC and all of its data. It can't be undone.

Our take: for organizations with frequent turnover, Deprovision now shortens the time a license sits unused during offboarding. Before using it, confirm the departing user's files have moved to OneDrive, SharePoint or another backup. Consider an internal approval step so no admin deletes a Cloud PC by mistake.

What this means for you

For Copilot and AI spend: Copilot Cowork adds usage-based cost on top of Microsoft 365 Copilot seats. Start on pay-as-you-go with budgets and alerts in the Cost Management dashboard, use a pilot to set a baseline, then evaluate Copilot Credit P3 or Microsoft Agent P3.

For server licensing and renewals: the CSP uplift and Windows Server 2016 end of support both hit server budgets over the next few months. Review annual-term software billed monthly ahead of renewals, and decide before January 12, 2027 whether each 2016 workload gets upgraded, covered by ESU or moved to Azure.

For Windows 365 Business admins: Deprovision now is optional, and the seven-day grace period stays the default. If your admins plan to use it, lock down data retention first, since deletion is permanent.
