Fletcher is using an old copy of Xenix on a computer in Virtual Machine and it's asking him questions about his MFN hard drive he can't answer: like cylinders and such. Leo suspects 124 cylinders, 255 heads, also a scuzzy drive.
Sarafine has a MacBook Air and two old PCs with unique programs on them that she uses. How can she consolidate them? She doesn't have installation discs. Leo says that Virtualization could work and have Sarafine can then eliminate both those old PCs. VMWare or Parallels is what Leo recommends. It will then enable Sarafine to run Windows virtually and access the data from the Cloud or an external hard drive. That way she won't have to worry about those old PCs dying on her. She can create a drive image of the hard drives and then open that image within Virtual Machine.
Roger wants to know why his audio recording software will stop working if he upgrades to Windows 10. Leo says it may work if you use Windows 7 in Virtual Machine, where it's in emulation inside of Windows 10. Leo recommends VMWare. It will preserve your installation as a single file and then use it on any computer. The only limitation may be the hardware interface or dongle you have to use with the software. The other option is to go dual boot, where your PC will give you the option to boot into Windows 7 or Windows 10 when you turn it on.
Terry has a MacBook Air, running Parallels so he can dual boot into Windows. After he upgraded to Windows 10, however, he had to upgrade Parallels and it trashed the drive. So he rebooted and reinstalled everything, and now Parallels wants him to pay for it again. Leo says that somewhere on the drive was a hidden file, perhaps in the application support folder, that has his registration data. So if he formatted the hard drive, Terry lost that data. Leo also says he'll have to reinstall Windows 7 again after installing Parallels.
Steve has a Windows 10 machine that he also runs Hyper-V Virtual Machine on, but he loses access to his USB ports in doing so. How can he access USB through Virtual Machine? Leo says it could be in the settings. VMWare has that access. He should look in the settings and see if he has to enable and assign it.
The chatroom says that Microsoft wants you to use Remote Desktop to pass it along. That seems counter-intuitive, but it may be that Microsoft didn't want to compete with VMWare.
Robert wants to refresh his Windows PC without losing any programs that he doesn't have discs for anymore. Leo says he's going to lose them, and there's no way around it. There are some apps that claim to move software over, but they don't really work all that great. It's very hit or miss. He could install another version of Windows and have two OS installed, but that'll take up a ton of space. If he has a secondary drive, and installs on that, then that would probably be the best way short of tracking down the program itself.
Leo says she should install the VirtualBox software in the same place she installs her other programs. She will install that first, then run it to set up a virtual machine. It will install the operating system from the ISO that she has, and it only will use that ISO once. So that can be located anywhere. In fact, Leo often puts ISOs on USB keys. The ISO is the operating system installer, essentially. Then, the virtual machine can be installed anywhere she wants. If she has a faster, or larger drive, she can put it there.
