As with any computer, it’s more than likely your OEM’s driver quality & amount that dictates these. Especially on laptops where OEMs just stop supporting random driver interfaces and you end up using the same “customized” audio driver for 4 years.
1: Fast Startup — aka hibernated kernel — disabled. It’s supposed to be slower with it off but it made no difference. (And I always prefer it off on modern hardware)
2: After you close whatever extra programs you opened, i.e.: the time it takes Windows itself to shutdown.
It's still pretty fast, but 20 seconds seems like a lot when you are used to 5. I usually just let the computer hibernate, but interestingly, that usually takes a lot more time than a cold boot. Probably because I usually have a ton of stuff open and using memory.
I'm assuming you've measured this can you provide stats I'd be curious which components of Windows 11 is causing this. I'm assuming you've downgraded to Windows 10 on this machine with the exact software versions loaded to determine this?
Causation and correlation are 2 separate things so I would caution you from making sweeping statements.
This is like 50% of answers on HN now, reread my comment, I didn't say Win 11 was slower because of my experience, I said that for me in my 2 laptops the newer one with windows 11 was slower, didn't make any conclusions out of it.
About the bloat and telemetry read the comment I was replying to, they said they just accept it as a force of nature, I said why accept it when you pay for it already, that's like having ads on a smart tv.
Now your problem is that you're so quick to try and prove other people's logic as wrong that you add imaginary statements to it so you can disprove them.
