Windows 10: Can I re-activate software licenses after resetting Windows 10?

I want to reset Windows 10 to factory settings and remove all apps and files. However, I'm worried about whether I'll be able to re-activate 3rd party software such as Vegas Video. Will my license keys still work when I reinstall software after resetting my PC?

Windows 10 upgrade license

Ahem... lost my activation when upgrading from AMD Phenom II to my XEON...
Installed "legit" activated Windows 7 Ultimate x64, and yes i paid for the license originally, but that key no longer works.. i paid more than enough to MS *Shadedshun :shadedshu:
Anyway once 7 is installed.. go here... Download Windows 10
Click Upgrade Now, it will give you a download with an app that gives you legit activated Windows 10 based on your Win 7 activation.

Click to expand... Yeah I went to that site, why do I need to buy a key?
I won't buy a key, stupid.

I'll revert back to windows 7 then.

When I still was on windows 7, about a year ago I added 4GB extra ram which is a total of 8GB now,
is that causing the problem?

From Why can't I activate Windows?

If you upgraded to Windows 10 for free and ended up in a non-activated state, try following these steps:

• Go to Start
  
  , then select Settings > Update & security > Activation.
• Select Go to Store, and check to see if a valid license is available for your device. If a license isn't available, you'll need to buy Windows from the Store.
  
  Note
  • This only applies if you haven't made changes to the hardware for your device.

or you could hack it with a crack but please note this is always risky and you don't know what's in the hack
