Treat a Classic Shell migration as a controlled change rather than assuming every old skin, setting, and extension transfers unchanged. Open-Shell continues the project lineage, but current releases and Windows integrations have evolved.
What to do
- Record the Classic Shell version and components in use. Export available settings and separately save skins, button images, and custom shortcut targets.
- Review Open-Shell project documentation and choose the components required for your current Windows version. Do not preserve a legacy Internet Explorer component without a reason.
- Install using the project installer and establish a working supplied style first. Then test a copy of an old settings export or custom resource only after saving the new baseline.
- Compare shortcuts, search, mouse and keyboard controls, and Explorer behavior. Keep unsupported resources out of the configuration and document any manual replacements.
Check the result
Confirm the new menu works after sign-in and that no two Start-menu replacements are competing for the same controls. Check imported paths for an old user name or installation directory.
Limits & precautions
Legacy skin documentation remains useful, but it does not certify every old resource against a current Windows build. Avoid copying old program DLLs into a new installation.
Questions & answers
Will every Classic Shell skin work unchanged?
Do not assume that. Match the menu style and test the resource against a built-in baseline.
Should I copy the old program folder over Open-Shell?
No. Use the installer and transfer settings and custom assets separately.
