12.4.1 Upgrade issues
Problems encountered during upgrades to Windows 9x will be related to hardware, software, or both. Before an upgrade is started, consult the Microsoft website to see if the hardware is compatible. Check with the manufacturers of the hardware components and the software publishers to determine if updated drivers are needed for the upgrade.

Prior to doing an upgrade, check that the hardware meets the minimum system recommendations for the upgrade. Microsoft has a list of recommendations available on their website that identify the type of processor and amount of RAM required to run the selected operating system.
