Microsoft officially ended support for Windows 10 on October 14, 2025. This means that businesses need a clear, immediate plan to stay secure and operational.
1. Identify Every Device Still Running Windows 10
Start by locating all remaining Windows 10 machines in your environment. Use the PC Health Check tool or your RMM dashboard to confirm the OS version on each device. This step shows you exactly how many machines are now unprotected and what level of response is required.
2. Upgrade Eligible Devices to Windows 11 Immediately
Some machines still qualify for a direct upgrade. If a device meets the minimum Windows 11 requirements:
-
Go to Start > Settings > Update & Security > Windows Update
-
Select Check for updates
-
Install the Windows 11 upgrade
This restores ongoing security patches and prevents unsupported systems from becoming weak points.
3. Decide What to Do With Devices That Can’t Run Windows 11
Unsupported hardware is now the largest security risk in your network. For machines that don’t meet Windows 11 requirements, you have two urgent paths:
Option A: Enroll in Microsoft’s Extended Security Updates (ESU)
The Consumer ESU program provides up to one year of critical security patches for Windows 10 devices after end of support.
This is a short-term bridge—not a long-term plan—but it buys time to transition safely.
Option B: Replace the Device
If the machine is too old to upgrade, replacing it with a Windows 11 or Copilot+ PC ensures full support going forward.
This avoids relying on stopgap measures that leave the business exposed.
4. Migrate Files, Settings, and Apps Without Disrupting Work
Whether you upgrade or replace devices, plan for file transfers and app setup. Use tools like:
-
OneDrive
-
Windows Backup
This avoids downtime and ensures nothing is lost in the transition.
5. Check Microsoft 365 and Office Compatibility
Microsoft 365 is not supported on an unsupported operating system. That means running it on Windows 10 now can create:
-
Sync issues
-
App instability
-
Security vulnerabilities
Upgrading the OS—or the device—is required to keep these apps supported.
6. Build a Refresh Plan so This Doesn’t Happen Again
To avoid future end-of-support scrambles, adopt a simple replacement cycle:
-
Every 3 years for high-use business laptops
-
Every 4–5 years for desktops and low-use machines
This keeps your hardware aligned with security requirements and ensures predictable budgeting.
