Unable to correctly read value of a REG_DWORD from the windows registry

Recommended Posts

I'm writing a little applet that basically tells you when Windows was installed.  There is a REG_DWORD in Windows that gives you this. It's basically a value that is the # of seconds from 1970.

The location is:  "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\InstallDate"

So if I run this in AutoIT, I should get the value displayed within the msgbox:

MsgBox($MB_SYSTEMMODAL, "InstallDate Test", RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion", "InstallDate"))

However, what happens is it always returns a value of "0"  I tried this on several machines (Windows 8, Windows 8.1 and Windows 10). 

Am I missing something?  If I manually view this REG_DWORD with RegEdit, it shows me the HEX value, or I can view the Decimal value. I don't care which value AutoIT reads, as I can always convert back and forth, but I just don't see why it can't read a value from this REG_DWORD.  As a test, I've read other REG_DWORD values, and with most it doesn't return any value, not even a 0.

Please, even if you guys have some other (perhaps better) way to read the Windows install date, I would still like to find a resolution to this problem, because I want to understand why I am having so much difficulty with reading REG_DWORD values from the Windows Registry with AutoIT.

Thanks for any help!

If your script is compiled as 32-bit you need to use HKLM64\SOFTWARE\Microsoft\Windows NT\CurrentVersion\InstallDate

      good morning everybody.
      today i liked to share an small example with you
      which it an function to read the registry values as an array
      the result array is 2d array witch
      $a_array[n][0] = value name
      $a_array[n][1] = value Data
      $a_array[0][0] = values count
      here's the function

      #include <Array.au3> #include <WinAPIReg.au3> #include <APIRegConstants.au3> Local $a_array = _RegReadToArray("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run") If @error Then     MsgBox(16, "error", @error)     Exit EndIf _ArrayDisplay($a_array) Func _RegReadToArray($s_RegKey)     Local $a_KeySplitInfo = StringSplit($s_RegKey, "\\", 2)     If UBound($a_KeySplitInfo) <= 1 Then         $a_KeySplitInfo = StringSplit($s_RegKey, "\", 2)         If UBound($a_KeySplitInfo) <= 1 Then Return (1, 1, 0)     EndIf     Local $H_KeyInfo = "", $s_RegKeyInfo = ""     Switch $a_KeySplitInfo[0]         Case "hklm", "HKEY_LOCAL_MACHINE", "hklm64", "HKEY_LOCAL_MACHINE64"             $H_KeyInfo = $HKEY_LOCAL_MACHINE         Case "hkCu", "HKEY_CURRENT_USER", "hkCU64", "HKEY_CURRENT_USER64"             $H_KeyInfo = $HKEY_CURRENT_USER         Case "hkCr", "HKEY_CLASSES_ROOT", "HKCR64", "HKEY_CLASSES_ROOT64"             $H_KeyInfo = $HKEY_CLASSES_ROOT         Case "HKU", "HKEY_USERS", "HKU64", "HKEY_USERS64"             $H_KeyInfo = $HKEY_USERS         Case Else             Return SetError(2, 2, 0)     EndSwitch     _ArrayDelete($a_KeySplitInfo, 0)     $s_RegKeyInfo = _ArrayToString($a_KeySplitInfo, "\")     Local $H_KeyInfoOpen = _WinAPI_RegOpenKey($H_KeyInfo, $s_RegKeyInfo, $KEY_READ)     Local $A_KeyInfo = _WinAPI_RegQueryInfoKey($H_KeyInfoOpen)     If @error Then Return SetError(1, 1, 0)     _WinAPI_RegCloseKey($H_KeyInfoOpen)     Local $A_RegVal[$A_KeyInfo[2] + 1][2]     Local $iV = 1, $s_RegRead = ""     While 1         $s_RegVal = RegEnumVal($s_RegKey, $iV)         If @error <> 0 Then ExitLoop         $s_RegRead = RegRead($s_RegKey, $s_RegVal)         If Not (@error) Then             $A_RegVal[$iV][0] = $s_RegVal             $A_RegVal[$iV][1] = $s_RegRead         EndIf         $iV += 1     WEnd     $A_RegVal[0][0] = UBound($A_RegVal) - 1     If $A_RegVal[0][0] >= 1 Then         Return $A_RegVal     Else         Return SetError(3, 3, 0)     EndIf EndFunc   ;==>_RegReadToArray
      i hope you benefit from it
      with my greetings

      Hi,
      I wondered why negative integers I wrote into registry (e.g. negative x-coordinates of a gui if using two monitors and the right one is the main one) wouldn't return right when reading. Now I know: it is saved as an unsigned integer (without algebraic sign). So here is a snippet that is changing unsigned to signed integer:
      Global Const $g_sRegKey = "HKEY_CURRENT_USER\Software\" & @ScriptName ; path to registry RegWrite($g_sRegKey, "Value", "REG_DWORD", -2147483647) ; write some negative integer into registry; -2147483647 highest possible negative integer , 2147483648 highest possible positive integer if talking of 32bit Local $sValue = RegRead($g_sRegKey, "Value") ; read out registry ConsoleWrite("Value: " & $sValue & @CRLF) ; show real value in console Local $sResult = _SignedInteger($sValue) ; change to signed value ConsoleWrite("Result: " & $sResult & @CRLF) ; and show it in console Func _SignedInteger($iUnsignedInteger) Local $iSignedInteger If $iUnsignedInteger > (2^31) Then ; then it means a negative integer $iSignedInteger = $iUnsignedInteger - (2^32) Else $iSignedInteger = $iUnsignedInteger EndIf Return $iSignedInteger EndFunc It took me some time to find out the problem and so I hope I can help somebody with this.
      Regards, Conrad

      I've looked at a bunch of SetACL examples on this site and none seem to be able to convert this batch script into a working AutoIt script.
      BATCH

      I want to determine if AutoLogon is enabled on a Windows 10 Pro (64-bit) system. It's my understanding that the following registry key will exist and equal 1 if autologon is enabled, or equal 0 if disabled. 
      Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\AutoAdminLogon So l looked up RegRead in AutoIt's help file and tested the example.
      #include <MsgBoxConstants.au3> Local $sVar = RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion", "ProgramFilesDir") MsgBox($MB_SYSTEMMODAL, "Program files are in:", $sVar) The resulting message box says:  C:\Program Files (x86)
      Regedit says the value in ProgramFilesDir is C:\Program Files. "C:\Program Files (x86)" is in a nearby key "ProgramFilesDir(x86)", which makes sense.
      I ignored this anomaly and tried RegRead in my own script:
      #include <MsgBoxConstants.au3> $isEnabled = RegRead("Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon", "AutoAdminLogon") If $isEnabled = 1 then MsgBox($MB_SYSTEMMODAL, "", "Autologon enabled.") Else MsgBox($MB_SYSTEMMODAL, "", "Autologon disabled.") EndIf My punishment for ignoring the problem with the Help file example is that regardless of whether the AutoAdminLogon key equals 0 or 1 in reality, my script's $isEnabled variable returns 0.
      Despite the problem with the RegRead example I still figure I'm at fault, but I would appreciate someone pointing out my mistake, please.
