Install Open-Shell from the project release installer, choose the components you actually need, and then select a Start menu style. Open-Shell Menu and Classic Explorer are separate features; installing the menu does not require enabling every Explorer extension.
What to do
- Check your Windows version with winver and note whether the computer is x64 or ARM64 in Settings > System > About. Record other Start menu or taskbar tools already installed.
- Save an XML backup of any existing Open-Shell configuration before changing versions. On a new installation, keep the first setup simple instead of importing an unfamiliar configuration.
- Open the release installer and review its source before accepting an elevation request. At the feature-selection screen, keep Open-Shell Menu selected and disable optional components you do not intend to use.
- Complete setup, open Settings for Open-Shell Menu, and select a built-in style. Apply the change and test both clicking Start and pressing the Windows key.
Check the result
Launch an app, open a folder from the menu, and sign out and in once. A successful setup should work for the intended Windows user without a repeated installer prompt.
Limits & precautions
Do not disable antivirus or Smart App Control to force installation. When Windows blocks a file, compare its provenance and release notes first; a newer preview is not automatically the right replacement for a stable build.
Questions & answers
Can I install only the Start menu?
Yes. The installer has component selection; leave Open-Shell Menu enabled and deselect unwanted extras.
Does setup replace Windows itself?
No. It adds shell customization components. Windows edition, updates, and activation are separate.
