Setting the ARPNOREMOVE property disables the Add or Remove Programs functionality in Control Panel that removes the product. For Windows 2000, this disables the Remove button for the product from the Add or Remove Programs in Control Panel. For earlier operating systems, this has the effect of removing the product from the list of installed products on the Add or Remove Programs in Control Panel.
If the ARPNOREMOVE property is set, the RegisterProduct action writes the value "NoRemove" under the registry key:
Setting the ARPNOREMOVE property prevents the UninstallString value from being written under this key. The UnistallString value is a command line for removing the product, rather than reconfiguring the product.
For example, this property can be set during a customization transform to prevent users from removing an administrator customization.
