Windows 10: Why I am seeing "Activate Windows- Go to settings to activate windows" ?

I have been searching for this message on internet since a while ago.

I have got something around it to fix it.


Do I need to buy a product key?

Where shall I buy the key from?


I found one link source : Activate Windows- Go to settings to activate windows

But looks like I should not even try tweaking any windows settings and pay for it. Shall I buy a key?

:)

 

Windows activation . . .

In the Windows activation status page is it still showing as activated, or do you have something like 3 days to do it in?

 

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 Activation?

Windows will do this if it detects a significant (their word, questionable use) hardware change, and will ask you to reactivate.

After a key has been activated X number of times, you will have to call to activate it.

Couple of tips for the phone call: You can use your keypad, and when they're telling you keys, instead of saying "Repeat that" and "Continue" type 1 and 2. With these tips, that activation call will only last you about 4 and a half minutes.
