Windows 10: I activated windows, my background has changed etc. but windows says I haven't activated it...

around 3 months ago I got my computer, and having issues custom built pc activating windows going to windows support, where it was eventually worked out. now one day I was having some different tech issues, reinstalling windows, signing on to my account to the fixed problem, but a watermark? if I restart my pc after turning it on, it will usually go away. I have no idea what to do, and the scripts to find my key won't work either opening cmd as admin, pasting in wmic path SoftwareLicensingService get OA3xOriginalProductKey.

windows activation—hardware changed siginficantly

From time to time on my thoroughbred PC, I get a Windows activation message that says my hardware changed siginificantly and I have to re-activate Windows. My hardware hasn't changed any more than a network card (went from a wireless g card to onboard lan to a wired network card), and the install is legit. Why is it doing this, and how can I stop it?

 

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.

 

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.
