Solved garlin's PowerShell scripts for updating Secure Boot CA 2023

Code:

Get-CimInstance -Class Win32_DiskDrive -Filter 'InterfaceType = "USB"' -KeyOnly | Get-CimAssociatedInstance -Association Win32_DiskDriveToDiskPartition -KeyOnly | Get-CimAssociatedInstance -Association Win32_LogicalDiskToPartition | select Name,Description

garlin · 2026-08-05T21:44:37-0400

No, I think you pasted more than the actual command. Try it again, and also this gem:

Code:

Get-CimInstance -Class Win32_DiskDrive -Filter 'InterfaceType = "USB"' -KeyOnly | Get-CimAssociatedInstance -ResultClassName Win32_DiskPartition -KeyOnly | Get-CimAssociatedInstance -ResultClassName Win32_LogicalDisk

Some smarty pants says this works around a PS 7.3.4 bug.

Klaver7 · 2026-08-05T21:47:31-0400

Code:

PS C:\Users\jwdav> Get-CimInstance -Class Win32_DiskDrive -Filter 'InterfaceType = "USB"' -KeyOnly | Get-CimAssociatedInstance -Association Win32_DiskDriveToDiskPartition -KeyOnly | Get-CimAssociatedInstance -Association Win32_LogicalDiskToPartition | select Name,Description

Name Description
---- -----------
F:   Removable Disk

Sorry went wrong copy 1st time I think

Klaver7 · 2026-08-05T21:49:39-0400

Code:

PS C:\Users\jwdav> Get-CimInstance -Class Win32_DiskDrive -Filter 'InterfaceType = "USB"' -KeyOnly | Get-CimAssociatedInstance -ResultClassName Win32_DiskPartition -KeyOnly | Get-CimAssociatedInstance -ResultClassName Win32_LogicalDisk

DeviceID DriveType ProviderName VolumeName  Size        FreeSpace
-------- --------- ------------ ----------  ----        ---------
F:       2                      MACLAPC2023 30766219264 29956145152


PS C:\Users\jwdav>

I think we have a winner for the shortest solution. Fingers crossed.

Klaver7 · 2026-08-05T22:11:22-0400

Code:

PS C:\Users\jwdav> powershell -nop -ep bypass -f E:\Z_c2023\PANTS.ps1
F
PS C:\Users\jwdav>

Is this what you hoping 4 ?

garlin · 2026-08-05T22:13:44-0400

If you only have one removable USB drive, and no DVD's mounted. YES.

Klaver7 · 2026-08-05T22:18:20-0400

I can plug in more USB drives but havent build any PC's with CD_ROM for years now

Klaver7 · 2026-08-05T22:20:16-0400

Got a portable CD Player but dont think I have any bootable CD's for it ....

But I can plug it in if needed.

garlin · 2026-08-05T22:28:19-0400

No, you take any actual ISO file (.iso) and right-menu from Explorer ("Mount"). Now you have a virtual DVD or "CD-ROM" device.

Klaver7 · 2026-08-05T22:34:00-0400

True, I am getting "old"

Code:

PS C:\Users\jwdav> powershell -nop -ep bypass -f E:\Z_c2023\PANTS.ps1
F
G
PS C:\Users\jwdav>

Quandary · 2026-08-05T22:58:11-0400

Same:

PS C:\WINDOWS\system32> powershell -nop -ep bypass -f "D:\Downloads\pants.ps1"
F
PS C:\WINDOWS\system32>

garlin · 2026-08-05T23:00:53-0400

Are you missing the Ventoy drive volumes?

Quandary · 2026-08-06T06:48:34-0400

No. Just did not have the Ventoy inserted, but here it is:

PS C:\WINDOWS\system32> powershell -nop -ep bypass -f "D:\Downloads\pants.ps1"
H
F
G

TheVisitor · 2026-08-06T06:55:04-0400

Here's my reading:
PowerShell 7.6.4
PS C:\Windows\System32> powershell -nop -ep bypass -f C:\temp16\pants.ps1
E
G

anchamp65 · 2026-08-06T09:00:18-0400

Wow !!!
You are incredible !!!

Code:

PS E:\Tmp> powershell -nop -ep bypass -f E:\tmp\PANTS.ps1
H
G

It even finds my USB that the OEM decided it was a "Fixed" USB flash drive

We have to thank "Fred Flintstone" on StackOverflow. Yabba dabba do!!
https://stackoverflow.com/questions...-of-usb-drive-in-powershell/76476869#76476869

Code:
This gets a single USB drive letter and stores it in the variable $DRIVE. Works in Powershell 7.3.4 where Get-WmiObject doesn't and where the USB drive shows up as Fixed as it does with Get-Volume.

Code:

$DRIVE = (Get-CimInstance -Class Win32_DiskDrive -Filter 'InterfaceType = "USB"' -KeyOnly | Get-CimAssociatedInstance -ResultClassName Win32_DiskPartition -KeyOnly | Get-CimAssociatedInstance -ResultClassName Win32_LogicalDisk).DeviceID

The internet is there to be used...

So is AI code generation, as long as we understand everything it generates before using it !

garlin · 2026-08-06T11:31:40-0400

I'm not good with "vibe coding". Usually it means your AI has no clue why the generated code can't be easily supportable (updated for other needs). It's usually ~~stealing~~ borrowing code examples written by someone else.

Only a human can offer background context, because it has previous working experiences. Like Mr. Flintstone knowing there's a PS bug. An AI would never infer that, unless it scraped that detail off the net. In complex programming, knowing the why is more important than the how.

Maybe in a few more years Elon Musk can suck the brains out of programmers using NeuroLink.
