Windows Components › Windows Installer
Enforce upgrade component rules
Supported on Windows Installer v3.0
What it does
This policy setting causes the Windows Installer to enforce strict rules for component upgrades. If you enable this policy setting, strict upgrade rules will be enforced by the Windows Installer which may cause some upgrades to fail. Upgrades can fail if they attempt to do one of the following: (1) Remove a component from a feature. This can also occur if you change the GUID of a component. The component identified by the original GUID appears to be removed and the component as identified by the new GUID appears as a new component. (2) Add a new feature to the top or middle of an existing feature tree. The new feature must be added as a new leaf feature to an existing feature tree. If you disable or do not configure this policy setting, the Windows Installer will use less restrictive rules for component upgrades.

These deployment candidates come from the ADMX template; they are separate from the native CSP mapping above.
- The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
- Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
