Slow startup when loading one-line profile on a SSD

Powershell takes a lot of time to launch, even on my computer with an SSD disk. It says “Loading personal and system profiles took 1031ms.” My only profile option is set at $PROFILE.AllUsersAllHosts, with a single line to disable deafening beep. Set-PSReadlineOption -BellStyle None. Even with the profile file deleted, powershell still takes quite a lot of time to launch, but less than with the profile. It used to take ~600ms to launch, but it jumped to ~1s after KB4025342 .

You might also try powershell -noprofile for Windows PowerShell to eliminate any profile as a factor
