I successfully upgraded all but one of our extended family's computers from Windows 7 to Windows 10 using the Media Creation Tool on DVD a few months ago. Have been slowly learning to use some of the new Windows 10 features/commands since then, especially the various DISM repair commands.
I think it's now time for me to create a Windows 10 System Repair Disk (CD/DVD), but I'd like to ask some basic questions first.
1. I believe the Windows 10 Media Creation Tool on DVD that I created a few months ago is considered a bootable DVD for repair purposes if my PC ever totally crashes. Is that correct?
2. Have there been any significant changes recently to the Windows 10 Media Creation Tool, whereby I need to replace my months old DVD copy with a brand new updated copy?
3. I was thinking about also creating a Windows 10 System Repair Disk (CD/DVD). (I saw there was also a way to create one on a USB, but It looked confusing, so I will probably skip that for now.) What are the basic differences between the Windows 10 System Repair Disk and the Media Creation Tool DVD?
4. Since I already have a Media Creation Tool DVD, do I really also need a Windows 10 System Repair Disk?
