The million dollar answer is that W7 (=Windows 7) is not supported on 7th gen processors.
What matters is what is supported versus what is not supported. It is difficult enough to assist with what is supported.
Since you are so sure of yourself, why even bother coming here and asking if it will damage your laptop?
I commend you on your efforts, but that is as far as it goes. When you need official support, where will you go? hmmm...
Have you read my statement and my question?
I always wanted to use W7 because of more performance, but due to the fact that microsoft blocked all updates for kaby lake, all of us don't have any choice but to use W10.
^ One point why I used W10(before) but changed to w7 since there are people who are using w7 in kaby lake.
Does it affect something on the processor?
I was sarcastic about the laptop destruction.
I never meant W7 as an operating system for productivity, I wanted it as gaming since most of my games in W10 lags out(mostly indie, less AAA). I used the Zeffy patch and I received 1 update as of now.
Microsoft claims that it's incompatible with Kaby Lake, it's true that some software or features are incompatible with windows 7, but that doesn't really mind me at all and all I want to use w7 for is performance.
Lastly, I have it as dual boot and Microsoft Live Agents didn't really helped me at all so that's why I did it by myself.
And, if you read my answer, it is the same: W7 (=Windows 7) is not supported on 7th gen processors.
Good luck with your efforts.
