Describe the feature or improvement

In Windows 11 there is a new 'feature' where application startup on boot is delayed until the system is considered idle. This can cause startup (of applications) to take a long time. Luckily this can be disabled with some registry editing:

See https://learn.microsoft.com/en-us/answers/questions/4059183/startup-apps-artificially-delayed-on-windows-11

Examples

Above link contains the registry keys to edit. Taken from there:

Windows Registry Editor Version 5.00 

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Serialize] 

"StartupDelayInMSec"=dword:00000000 

"WaitForIdleState"=dword:00000000

Additional context

It is probably good to provide context with this change, on slow computers, this will not improve things but might make them worse. WaitForIdleState is the main culprit for the delay, so that should definitely be set to 0. There might be valid reasons to keep the StartupDelayInMSec set to something other than 0 (configurable?), but for me it has been working fine.
