Query reg key with unique value

PowerShell Help

how can i find a reg key recursively with a unique value compared to keys with the same name in a subtree? this is what i have so far, with -notlike being the value of all the keys that dont have a unique value.

this unfortunately doesnt find the reg key for BestViewOption with the unique value. where is my code wrong?

$SearchPath = "HKLM:\SYSTEM\ControlSet001\Control\Video\$VideoID"

$VideoID = Get-ItemPropertyValue -Path "HKLM:SYSTEM\ControlSet001\Enum\$HWID\Device Parameters" -Name VideoID

foreach ($Path in @(Get-ChildItem $SearchPath -Recurse |% { Get-ItemProperty $_.PSPATH -Name *BestViewOption* | select PSPath } | Sort-Object -Unique | Convert-Path | Where-Object { $_.Data -notlike ([byte[]]@(0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x08,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x09,0x00,0x00,0x00,0x00,0x00,0x00,0x00))})) {
    $Path

$DisplayPathNumber = Select-String -InputObject $Path -Pattern "(?<=DisplayPath_).*?(?=\\Option)"

$DisplayPathNumber.Matches.Value

$DisplayPathDigit = $DisplayPathNumber.Matches.Value

$DisplayPathDigit
}
}

when a user chooses the HDMI option, it outputs the DisplayPath correctly at the end of the EDID string as its looking for a specific reg key, instead of a specific reg key value like the above code is trying to do. this code below is working.

$SearchPath = "HKLM:\SYSTEM\ControlSet001\Control\Video\$VideoID"

$VideoID = Get-ItemPropertyValue -Path "HKLM:SYSTEM\ControlSet001\Enum\$HWID\Device Parameters" -Name VideoID

foreach ($Path in @(Get-ChildItem $SearchPath -Recurse |% { Get-ItemProperty $_.PSPATH -Name *BestViewOption_Hdmi* | select PSPath } | Sort-Object -Unique | Convert-Path)) {
    $Path

$DisplayPathNumber = Select-String -InputObject $Path -Pattern "(?<=DisplayPath_).*?(?=\\Option)"

$DisplayPathNumber.Matches.Value

$DisplayPathDigit = $DisplayPathNumber.Matches.Value

$DisplayPathDigit
}
}

the output should choose the value at the end of this string, which is the DisplayPath being 12 in this instance

EDID_44048_41219_DELL AW2518HF_12

i want the DisplayPath added at the end of the EDID string the same way, except this is for DisplayPort input. there is no unique reg key this time, only a unique reg key value its looking for. how can i get powershell to search recursively through the specified subtree for the instance of a unique BestViewOption reg key specified?

shoober420,
Welcome to the forum. :wave:t3:

When you crosspost the same question at the same time to different forums you should at least post links to the other forums along with your question to avoid people willing to help you potentially wasting their time.

Thanks

here is the fixed string

2 {foreach ($Path in @(Get-ChildItem $SearchPath -Recurse |% { Get-ItemProperty $_.PSPATH -Name BestViewOption } | Where-Object { (Compare-Object $_.BestViewOption $DisplayPortBinaryInactive -SyncWindow 0).Count -notlike 0 } )) {
    $Path
