Having this available on a bootable USB stick if anything goes wrong on your windows system is SUPER handy and has saved me countless times. This “Redstone” distribution packs about 4GB of very useful programs and a fully functional super smooth version of Windows 10 into one ISO that can be installed on and booted from a USB drive. At the moment, one of the most handy Windows PE distributions is Gandalf’s Win10 PE Redstone.
