Windows 10 EOS: What Stops on Oct 14, 2025?
On October 14, 2025, Windows 10 reaches the end of support: no more security or feature updates, and no Microsoft tech support. Your PC will still run, but the risk rises unless you upgrade or enroll in ESU.
Security & feature updates + Microsoft support stop for Windows 10.
Extended Security Updates (ESU) can keep critical/important patches flowing after EOS (no features/support). Options include free enrollment via Windows Backup or Microsoft Rewards, or $30 USD for individuals; commercial ESU starts at $61/device (year 1).
Microsoft 365 Apps: will continue receiving security updates on Windows 10 through Oct 10, 2028 (feature updates through Aug 2026), easing migration.
Microsoft Defender Antivirus will keep getting Security Intelligence updates through 2028 on Windows 10.
1) Inventory Windows 10 and flag pre-22H2 devices (PowerShell)
$os = Get-CimInstance Win32_OperatingSystem
$ver = (Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion").DisplayVersion
[pscustomobject]@{
PC = $env:COMPUTERNAME; Caption = $os.Caption; Version = $os.Version
Build = $os.BuildNumber; DisplayVersion = $ver
} | Export-Csv .\win10_inventory.csv -NoTypeInformation
if ($os.Caption -like "*Windows 10*" -and $ver -ne "22H2") {
Write-Warning "Upgrade to Windows 10 22H2 before ESU."
}
(Why? ESU enrollment targets supported builds; 22H2 is the final Windows 10 release.)

2) Find Windows 10 endpoints in Microsoft Defender (KQL)
DeviceInfo
| where OSVersion startswith "10.0"
| project DeviceName, OSVersion, DeviceId
Run in Advanced Hunting to list Windows 10 devices needing action.
3) Check Windows 11 readiness signals (PowerShell)
$tpm = Get-CimInstance -ClassName Win32_Tpm -ErrorAction SilentlyContinue
"TPM Present: " + [bool]$tpm
try { "Secure Boot: " + (Confirm-SecureBootUEFI) } catch { "Secure Boot: Not supported/disabled" }
Helpful to scope upgrades vs. ESU bridging.

Upgrade to Windows 11 for security-by-default and ongoing support.
Bridge with ESU (limited-time) to buy planning time; remember this does not add features or support.
