Unable to recursively delete registry keys

8 posts in this topic

When using RegDelete, I am unable to delete registry keys if they contain children. I have to delete all of the children first before I am able to delete the parent. This happens on my X64 box, the same code works on X86. The keys I'm trying to delete lie in HKEY_LOCAL_MACHINE\Wow6432Node\Software, using RegDelete('HKLM\Software\keyname') it fails because 'HKLM\Software\keyname\childkeyname' exists. Is this intended behavior? In this situation, @error is set to -2. I am able to delete childkeyname and then keyname in that order. I don't mind being forced to enumerate all child keys, but I don't want to use WMI.

Is this intended behavior on X64?

Carefully read RegEnumKey()

Hint: You might need to use HKLM64

I am able to delete the children first, then the parent. It's not that I can't delete the keys, I would just need to cycle through all children and grandchildren registry keys before I am able to delete the parent key. I started to look at the RegKeyDelete function in advapi32.dll, but I didn't try too hard yet.

You may need to use RegEnumKey to help create a RegDelete loop before deleting the parent.

I figured out how to do this by the way.

DllCall("shlwapi.dll", "long", "SHDeleteKey", "long", 2147483650, "string", "Software\\Test")

I think i know why this is happenning. Because you've deleted a key in loop, automaticly it's number decreasing but your loop still increasing.

so doing something like this will probably solve the problem:

For $i = 1 to 100
$var = RegEnumVal("HKLM"& $mimari&"SOFTWAREMicrosoftInternet ExplorerToolbar", $i)
If @error <> 0 Then ExitLoop
$read = RegRead("HKLM"& $mimari &"SOFTWAREMicrosoftInternet ExplorerToolbar", $var)
$result_no = StringInStr($var, "Locked")
$result_yes = StringInStr($var, "-")
if $result_no == 0 and $result_yes > 0 Then
MsgBox(4096, "durum", $read & " - read var -" & $var)
$result = RegDelete("HKLM"& $mimari &"SOFTWAREMicrosoftInternet ExplorerToolbar", $var)
$i = $i-1 ; this is needed for right iteration because you have already deleted one
MsgBox(4096, "durum", $result)
EndIf
Next

I know thread is old but while i'm googling i saw this and suddenly realized the solution.
