Upgrades on unsupported hardware

Keep older PCs and virtual machines that already run Windows 11 24H2 moving to newer versions with the enablement package.

Updated

On this page

Many computers already run Windows 11 24H2 although Microsoft doesn't support their processor, TPM, firmware, Secure Boot or memory. This is common with older PCs and virtual machines. Windows Update never offers them the next version, so without help they would stay behind forever and show as blocked in Patching → Windows versions.

What the setting does

Allow on unsupported hardware lets such a device take the enablement package: the small update that only switches on the new version's features of the Windows 11 it already runs. The agent then no longer stops at Microsoft's hardware appraisal for the Windows Update and enablement package methods.

It does not:

  • allow a full upgrade with Windows setup on unsupported hardware (still refused);
  • get past a system drive that's too small (always blocks);
  • move Windows 10 or Windows 11 23H2 devices, which need a full upgrade.

Requirements

  • The device already runs Windows 11 24H2 or later.
  • The target version has an enablement package that Revo offers (25H2: KB5054156; 26H2: KB5121794) for the device's processor type.
  • The policy allows the enablement package method.
  • Agent 0.6.0 or later.

Turn it on

Only owners and admins can change it.

  • One device: the device's Settings → Windows version → Allow on unsupported hardware.
  • Everyone on a policy: the policy's Windows version section → Allow on unsupported hardware.

Each change is audited, and so is every upgrade job sent under this setting, with whether the device or its policy allowed it.

How to tell it's the hardware

In Patching → Windows versions, expand a blocked device. Its readiness shows which requirement fails: TPM 2.0, Secure Boot, processor, UEFI or memory. A device blocked only by those can use this setting; one blocked by disk space needs space freed first (at least 25 GB on the system drive is a good rule for a full upgrade).
