Windows 10: Can you reinstall windows 10 on a non activated copy of windows 10

Hi, I do not mean to break rules but as of typing this now, I used to have windows activated on a laptop, but I need to activate windows again and I don’t have the key anymore and I do not want to spend money on a product key. I am using a non pirated windows 10 . Anyways, I had a problem that required me to reinstall windows and I am asking if I can reinstall windows on a non activated copy of windows and use windows not activated as I do not want to spend money on windows 10 key for some reasons including saving money. I already made a USB and I have multiple laptops and 1 desktop.

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

Windows 10 Activation (Insider)

This kinda sucks. However, if one is upgrading from a retail W7/8, then it should activate on different hardware, with possible phone activation required if it's been over 120 days or whatever the timeout period is now since the last activation. Remember to erase the copy on the old hardware, of course.

 

Windows 10 Activation (Insider)

umm ok.. I guess I don't understand. So, my key is blacklisted, so I can't activate. How do I have a legit copy of Windows 10 if my key is useless?
