After the latest Windows 11 25H2 update, my Corsair USB keyboard as well as my Razer mouse macros were not working.

I had to do a second reboot after logging in to get them to work.

Downgraded from Synapse 4 to Synapse 3, same issue
Removed all profiles from mouse, reset, added just a single one, same issue
Always had to unplug and replug the keyboard after initial boot to just get it to work

Turning off FastBoot fixed everything! Seems rebooting once in the OS bypasses fast boot.
Now, when I just turn on the PC, everything works again, no second reboot needed.

Did you update to 25H2 manually or did MS sneak it in on you?

I just upgraded from Home to Pro with a new key yesterday and after finishing all the updating it’s still on 24H2.

I think you are confusing Fastboot, which is a bios setting, with Fast startup in windows. Fast startup in windows makes the computer "hibernate" instead of shutting down. A reboot forces a full shut down

Once you disable hibernation, you will not even have the option in your picture. I don't.

Actually they are related. If fast boot is disabled in the UEFI, fast start doesnt work and Windows logs an error in the event log every time you boot about it.

On a desktop, fast boot in the UEFI and fast startup in Windows should both be disabled for best function. These were really meant for fixed hardware devices like laptops, tablets, and mini PC/all-in-ones.

They are not related. UEFI Fast Boot skips hardware initialization in the bios during power-on (saving maybe 2 seconds), while Windows Fast Startup is a power-saving feature that hibernates the Windows kernel on shutdown to load it faster on the next boot.

You can turn off fast boot in the bios, and STILL enable fast startup in Windows, and the other way around as well. Not sure where you got that from.

Fast boot in the UEFI will have no effect on the function of windows at all. Just makes it harder to get into the bios, so I disable it.

I disable hibernation, because I have no use for it, modern NVmE drives boot so fast it's pointless.

IMO hybrid sleep is such a sensible no-brainer default feature to have that I'm surprised it hasn't become a default / easily selectable option on Linux, but to each their own I guess.

To those that don't know: hybrid sleep (aka. the sleep mode feature on default settings) takes about 30 seconds to kick in because Windows saves the contents of RAM to the hibernation file. In the event of an unexpected loss of power, Windows falls back to loading the contents of RAM from the hibernation file.

Hibernation is not the same as hybrid sleep. I use sleep daily, with hibernation disabled...I have adequate power backups, so losing work is not a concern.

I know it's not, however, hybrid sleep also uses the hibernate file as a backup for the reason I already stated. It's why a system going into non-hybrid-sleep will enter sleep mode within a second or two whereas the default hybrid sleep feature takes about 30 seconds to engage.

- edit - I find it odd that you would supply a linked article that confirms what I'm saying. Did you not read it?

It confirmed they were different, and that plain old "sleep" is much faster.

Sleep mode is NOT the same as hybrid sleep, or hibernation. If it were, I could not use sleep with hibernation disabled.

Hybrid sleep is enabled by default, so when the average person sees "sleep mode", they're actually using hybrid sleep. It's fine to strip away protection features if one knows that's what they're doing. My original response was intended as information for others reading the thread who don't know.

This is aside of course from a lot of modern laptops that don't do S3 sleep any more.

Bring 24H2 up to date i.e. cumulative update and then run this:


Once 24H2 is fully up to date, it is the same code base as 25H2 just with the 25H2 things disabled. The "enablement package" (KB5054156) download size is less than 200KB that 'upgrades' 24H2 to 25H2.
