Question upgraded mobo and cpu without reinstalling windows

[jaychtan2016]

Hi,
I have just upgraded my mobo from b450 pro max to b550 pro vdh, and my cpu from r7 3700x to r9 5900x.
I was planning to reinstall the windows, but failed to get into bios on boot up to choose boot up on usb for windows installing, so i decided to see how it will turn out, so i let it boot up with the old windows in my ssd.
Everything seems to be running perfectly fine and normal without any issue as if nothing has changed other than the performance is obviously better.

So my question is, shall i just leave it and continue using my pc or its better to reinstall my windows fresh?

any advice?
thanks in advance

(deep down, i actually feel kinda lazy to reinstall all the softwares, games, programs then get into settings of each of them etc etc.. its at least few hours of work.)

Changing the motherboard, and keeping the old drive+OS, there are 3 possible outcomes:

1. It works just fine.
2. It fails completely.
3. It "works", but you're chasing issues for weeks/months.

I've personally seen all 3.

You may just be one of the lucky ones with #1.
Or, you're in #3 and just don't know it yet.

Possibles could be anything. Nothing specific to look for.

Who know. You could find an odd crippling problem six months from now and have to install anyway.

I try to follow best practices unless there's a specific reason I absolutely cannot (and laziness doesn't count in my book). So a fresh install.
