When I run this powershell script, the script keeps freezing. It either intermittently hangs on checkMissingFeatures(); this function calls Get-WindowsOptionalFeature

Does anybody know how to fix this issue?

• For such questions, you will have to describe clearly the underlying environments, such as Windows editions and versions when you observe an issue. – Lex Li Commented Mar 25 at 1:11
• Ok, I’m running Windows 11, I will check the other information next morning when I get into work. – Erik343 Commented Mar 25 at 1:28
• Overall, it is a script in bad shape. You can do a single Get-WindowsOptionalFeature -Online and then figure out the states of multiple features, but in this script it wastes all the time running that slow command over and over again. – Lex Li Commented Mar 25 at 1:40
• Does Get-WindowsOptionalFeature require a stable Internet connection because we have a corporate firewall? – Erik343 Commented Mar 25 at 1:53
• 1 Is it actually "hanging" or just running slowly? Add a load of console logging with timestamps - e.g. write-host "$([datetime]::Now) doing something..." and see if it shows the output. If it looks like it's hanging, add some more logging around the bit of code that appears to have frozen, and gradually narrow it down to where the bottleneck is. – mclayton Commented Mar 25 at 9:23

I found that if you disable quick edit, the powershell script works!

This is my .bat file

reg add HKCU\Console /v QuickEdit /t REG_DWORD /d 0 /f
Start "My Installer" powershell.exe -NoProfile -executionpolicy unrestricted .\INSTALL.ps1

I just edited the registry to disable quick edit:

HKEY_CURRENT_USER\Console\QuickEdit

A 1 value is enabled, and a 0 is disabled.
