- You have a Windows 8 PC.
- You have an application installed that adds a ContextMenuHandlers key to the registry to create a context menu. Context Menu Handlers are sometimes used to add custom menu items, such as additional device properties when you right-click on a device. For example, a printer device may provide additional device-specific menu items after a printer extension application has been installed.
- After the application is installed, you upgrade the Windows 8 PC to Windows 8.1.
- During the Windows upgrade process, you select the setting for "Keep Windows settings, personal files, and apps." Or, you initiate the upgrade via the Windows Store app (which automatically uses this setting).
If an application writes to the registry with this key, some features of the application may not work properly after the Windows 8.1 upgrade.
