For business who wish to develop Line of Business (LOB) apps for Windows 8 and Windows Server 2012, Microsoft introduces the concept of sideloading so that companies with private apps can deploy apps without needing to publicly publish to the Windows Store.
Before you can add or run sideloaded LOB apps, your Windows 8 and Windows Server 2012 apps must be joined to an Active Directory domain that has the "Allow all trusted applications to install" Group Policy setting enabled. For devices running on Windows 8 Enterprise and Windows 8 Pro that are not joined to a domain, you must activate sideloading with a sideloading product key on the device.
Edit Group Policy settings
- Open the Group Policy editor from a computer running Windows 8.
- Under Local Computer Policy in the left pane, click to expand Computer Configuration, Administrative Templates, Windows Components, and then App Package Deployment.
- Double-click the Allow all trusted apps to install setting.
- In the Allow all trusted apps to install window, click Enabled, then click OK.
Activate a sideloading product key
- Open the command prompt with
administrator privileges and type the following:
- Slmgr /ipk <25 digit sideloading product key>
- Activate the key by typing:
- Slmgr /ato ec67814b-30e6-4a50-bf7b-d55daf729d1e
