I have two machines running Windows 7 Ultimate 64bit, one workstation and one laptop. Both about two years old but fairly powerful and with SSD disks. (But not with UEFI BIOS)
I am considering upgrading them to Windows 8 Enterprise 64bit. (All installations are legal. I have media and purchased Product Keys. RTM, not preview. Same language: English.)
My main concern is whether to do a scratch installation or an in place upgrade.
Obviously an in place upgrade would be less work and faster, thus better - if it works well.
Anyone with experience of such an in place upgrade? Does it work? How well, generally? How much is preserved?
Do programs continue to work as before? Device drivers?
Any confusing/irritating artifacts left by the upgrade?
Do you get the same/similar speed improvements as scratch installations?
