#214224 - 2023-06-16 12:48 AM WriteValue does not modify existing value but creates a duplicate one
fobrien fobrien Just in Town Registered: 2022-08-19 Posts: 3 Loc: France	Hello everybody, I am posting this message as I am having some issues in order to modify an existing registry key in Windows using this code : Code: $rc=WriteValue("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced","TaskbarAI","0","REG_DWORD") Even in the great book by Bob Kelly, it is mentioned that such command is supposed to create/modify a value depending on the context. I really do not understand the reason why I am having a duplicate key instead. At the moment, I am trying to make it work on a Windows 10 64 bits Operating System. Would you have any idea ? Thanks in advance for your help. Fred

You can disable this in Kix Code: $Rc = SetOption('Explicit', 'On') $Rc = SetOption('WrapAtEOL', 'On') $Rc = SetOption('NoVarsInStrings', 'On') $Rc = SetOption('NoMacrosInStrings', 'On') $Rc = SetOption('WOW64AlternateRegView', 'Off') The first 4 lines are recommended for good programming practices, but the last line is key to this - it disables the reflection. Try adding that line to the top of your script and see if it helps. _________________________ Actually I am a Rocket Scientist! $\:D$

Unfortunaetely, the following code also creates a duplicate entry of the existing key already present in the system : Code: $Rc = SetOption('Explicit', 'On') $Rc = SetOption('WrapAtEOL', 'On') $Rc = SetOption('NoVarsInStrings', 'On') $Rc = SetOption('NoMacrosInStrings', 'On') $Rc = SetOption('WOW64AlternateRegView', 'Off') $Rc = WriteValue("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced","TaskbarAI","0","REG_DWORD") Am I doing something wrong and is there another method to modify an existing registry key value ? Is it the best way by deleting the existing registry key first, then create it afterwards, for instance ? Thanks in advance. Fred

Are you saying you see TaskbarAI listed twice in HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced ? Please provide the OS, x86 or x64, the kix version, what permissions do you have?

Glenn Barnas Glenn Barnas KiX Supporter Registered: 2003-01-28 Posts: 4401 Loc: New Jersey	I just tested your code via the following steps: 1. Open a command prompt 2. Launch Regedit (my user context - NOT a local admin) Confirm that the TaskbarAi value does not exist. 3. Create rtest.kix with "Break On" followed by your command copied/pasted. 4. Run rtest.kix - refresh RedEdit - confirmed that the TaskbarAi value is set I'm using Kix 4.66, running an x64 platform as a non-admin user. This worked without any issue. It's not really possible to create two identical entries in the registry, so there needs to be some subtle difference. Spelling? Space? Special Character? Make sure your script is saved in ANSI format, not UNICODE, delete the two values and tru your script again. _________________________ Actually I am a Rocket Scientist! $\:D$

fobrien fobrien Just in Town Registered: 2022-08-19 Posts: 3 Loc: France	Hi Glen/Allen, Thank you for our feedback and these tests. I feel shameful but I have eventually found what the issue was. Indeed, when checking the registry entry from a PowerShell Terminal (I am running Windows 11 Professional 64 Bits), then I noticed that the key name was mispelled and I got confused between a capital "I" and a lower case for letter "l". Therefore, correcting the key name dd the trick. Image 1 Image 2 Sorry for this mistake anyway. Fred
