Can you tell me how and where to access Virtual Machine?
A Virtual Machine is something you make yourself using Virtual Machine software like Virtual PC, VMware, VirtualBox, etc. A Virtual machine is a virtual computer, sort of like a computer inside a computer. You start the Virtual Machine software, you use it to create a virtual hard drive, then install Windows 98 on the virtual hard drive. You'll need a Windows 95 or 98 install CD.
If you have Windows 7, you can use Microsoft's Virtual PC 2007.
You can read about how to use Virtual PC 2007 at ***the Metzomagic site***
I'd recommend using VMware Player instead of Virtual PC if you have Windows 8 or 10. It's difficult to install Virtual PC on Windows 8 and it's probably impossible to install it on Windows 10.
You can get Virtual PC 2007 from https://www.microsoft.com/en-us/download/details.aspx?id=4580
and Virtual PC 2007 SP1 from https://www.microsoft.com/en-us/download/details.aspx?id=24439
I've used both on Windows 7 both can be run with Windows 98 virtual machines. As far as I know the only difference is that SP1 can support newer versions of Windows being installed inside the virtual machine.
