windows 10 home laggy

when I fresh install my win 10 1903 version it works fine for 3 days it then starts giving some UI lag like when I open edge browser transition is not smooth then I try to open new tab it also lags then I open chrome its UI also lags also in gaming it worked fine for 3 days now I have constant 60 fps in game suddenly some cpu spike comes in between fps drops to 45 for a few seconds then back to normal is there any tweak guide for gaming thanks

Win 10 1903 came with a lot of bugs.
The lag is probably due to windows update downloading / installing the patches to correct the bugs.
Run WU manually and restart your computer.

Check your maximum CPU clock speed is 100 in Power Options
