Windows 10: Having trouble activating windows vista says security error

it just says security error and i cant get it to work i really wanted to get this activated because i found a key on my computer case

:)

 

Windows Vista Activation

I have 4 sytems in my home running vista(1 ult.-3 prem).The ultimate & 1 premium took SP1
wthout a hitch.1 premium required re-activation?,The other premium did not list SP1 in windows up-date,So i manually installed it without any re-activation required.
Also have to add that SP1 has increased performance in every comp.The ultimate machine actually got a 1,100 point increase in 3d 06 without any other changes at all.

 

Windows 10 will not activate Error code 0x803F7001

Possibly there can be the problem with Microsoft activation Server, so your Windows 10 is not activated. In this scenario, you need to wait and verify if it is the issue from Microsoft’s side. But if you are getting error code 0x803f7001, you can also try these steps:

1. Open Settings app. Then go to Update and security > Activation screen > Change product.
2. Type your Windows edition product key and click Next.
3. You’ll get We couldn’t activate Windows error message.
4. Retry steps 1-3 then type your 25-characters unique product key.
5. Wait for the process to complete, Windows 10 is activated.

Hope something helps this problem
