Prerequisites

• Make sure you are able to repro it on the latest released version
• Search the existing issues.
• Refer to the FAQ.
• Refer to Differences between Windows PowerShell 5.1 and PowerShell.

Steps to reproduce

I installed these updates yesterday:

Since then, PowerShell 7.4.2 takes about three minutes to load, even when I use pwsh.exe -NoProfile. Since there's no difference in behavior with or without loading the profile, here's an example when I do load with a profile so you can see the load time.

PowerShell 7.4.2
Loading personal and system profiles took 180574ms.

Even after loading, everything is glacially slow. For example:

PS C:\Users\Chad> Measure-Command { Get-Date }

Days              : 0
Hours             : 0
Minutes           : 0
Seconds           : 10
Milliseconds      : 11
Ticks             : 100117544
TotalDays         : 0.000115876787037037
TotalHours        : 0.00278104288888889
TotalMinutes      : 0.166862573333333
TotalSeconds      : 10.0117544
TotalMilliseconds : 10011.7544

Things I've tried:

• pwsh.exe -NoProfile
• pwsh.exe -NoProfile -NonInteractive
• POWERSHELL_TELEMETRY_OPTOUT = 1 and POWERSHELL_UPDATECHECK = Off
• Verified that Controlled Folder Access is set to Not configured (Issue https://github.com/PowerShell/PowerShell/issues/21546 has similar symptoms)
• Reinstalled 7.4.2

Expected behavior

Acceptable performance

Reproduzieren Sie die Verlangsamung mit pwsh.exe -NoProfile und Measure-Command { Get-Date } in der gemeldeten PowerShell 7.4.2-Windows-Umgebung und vergleichen Sie anschließend den Start mit und ohne Profile. Prüfen Sie die Symptome und das zugehörige Issue #21546; als erledigt gilt die Aufgabe, wenn Start und grundlegende Befehle wieder eine akzeptable Leistung erreichen und die Regression durch einen geeigneten Test oder eine Diagnose abgedeckt ist.
