Windows 10: Do I have to format a hdd on a new windows 10 PC that has windows 7 on it?

so lately I've been trying to recover data off a HDD I took it out of a 9 year old laptop replaced it with my main drive in my PC booted up into bios and surprisingly it's still alive healthy and quite! I booted onto it with windows 7 everything worked fine besides the mouse and keyboards and it had a password on itnow my question is can I use it as a second drive and get my files in windows 10 in file explorer?people have been saying I don't need to format it since it pretty much uses the same system and it could be able to read it without needing to format it but idk I cannot get the answer

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

Installing Windows 10 using Windows 7 key

Hi guys,
Okay, so I wanted to know, I currently have a pc at home with a paid Windows 7 installed. I am getting a new computer either Friday or Monday with an SSD. Seeing as I want Windows 10 now and not 7 and I want it on my SSD how to I get to do this. I already downloaded a Windows 10 file in order to make one of my flash drives eligible for a windows 10 installation.

Will it be possible for me to just install windows 10 on the new SSD with this flash drive using my Windows 7 key, whilst my original windows 7 is still installed on the old Hard drive. And if it is how to I go about deleting my old OS from the HDD, seeing as I also want to use that HDD in my new pc, without formatting all the games I have on it currently?

Thank you in advance

 

Windows 10 formatting ?

We upgraded windows 7 to 10. Many crashes and errors after that. So a format and clean install of windows 10. Activated automatically. Zero issues and no more crashes etc etc.
So I'm inclined to say to just go for it. And if a problem, then use your windows 7 key.
