Your Microsoft mouse will work with basic functionality when running the Windows(R) 7 operating system prior to installing the IntelliPoint software. Installing the software is required for full functionality.
Regardless of whether you purchased the keyboard and mouse together in a desktop set, you must run Setup for the mouse and the keyboard separately.
Microsoft is aware of the following known issues when using IntelliPoint 7.0 with Windows 7.
1.1 The magnifier feature might appear jittery when moved. When resizing the magnifier, the screen might flash black.
1.2 Complete device information might not be displayed in Windows 7 Devices and Printers.
