Windows 10: "Activate Windows" message on a already activated Windows

Hi,since I updated to 1903,the message on the border of the screen saying that I need to activate Windows appears two times daily,one at afternoon and one during dawn,this is annoying and also causes fps drops on the videogame I'm playing when this happens,as I stated on the subject,Windows is already activated and has always been (this didn't happened during 1809 or lower),if I re-start the message disappears until the next afternoon or dawn arrives,I thought that my license was invalid nowadays so I bought another and even with this new license the problem continues,I don't really know what to do and It's annoying me a lot,I greatly appreciate any help.

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—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?
