Notes

• Note that if you are running OEM Service Release version 2.1, you see the version number 4.00.950B (the same as OSR2) when you follow the steps above. To determine whether you are running OSR 2.1, check for "USB Supplement to OSR2" in the list of installed programs in the Add/Remove Programs tool in Control Panel, and check for version 4.03.1212 of the Ntkern.vxd file in the Windows\System\Vmm32 folder.
• If you are running OSR2.5 and you uninstall the USB Supplement using the Add/Remove Programs tool in Control Panel, the version number changes to 4.00.950b on the General tab in System properties.

1. In Control Panel, double-click System.

2. Click the General tab.

3. Locate the Product ID number under the Registered To heading. This number typically contains 20 digits. If digits 7, 8, and 9 contain the letters "OEM," you have an OEM installation of Windows 95. For example, the following sample Product ID number indicates an OEM installation:

         12345-OEM-6789098-76543
