The system was unable to find the specified registry key or value

[Docfxit]

In a batch file I have:

Code: Select all

set "RegKey="HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify""
reg delete %regkey% /v PastIconsStream=- /f

This is what I get when I run it:

Code: Select all

C:\Windows\System32>reg delete "HKCU\Software\Classes\Local Settings\Software\Mi
crosoft\Windows\CurrentVersion\TrayNotify" /v PastIconsStream=- /f
ERROR: The system was unable to find the specified registry key or value.

I have been able to code it a little different so it finds the key but then it doesn't recognize the /f and asks me if I want to delete it.
How can it be changed to find the key?

Thanks,

Right now I created that value and tried to delete it using your line. It perfectly works for me. But the value name PastIconsStream=- seems to be weird. Are you sure the =- belong to the name or isn't it rather only PastIconsStream?

This is what the key looks like coming from the registry:

Code: Select all

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify]
"PromotedIconCache"="{7820NR76-23R3-4229-82P1-R41PO67Q5O9P},{7820NR75-23R3-4229-82P1-R41PO67Q5O9P},{7820NR74-23R3-4229-82P1-R41PO67Q5O9P},{7820NR73-23R3-4229-82P1-R41PO67Q5O9P}"

This finds the registry key but requires me to answer the delete:

Code: Select all

set "RegKey=HKEY_LOCAL_MACHINE\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify" /v "PastIconsStream"=-"
reg delete "%regkey%" /f

And I get this:

Code: Select all

set "RegKey=HKEY_LOCAL_MACHINE\Software\Classes\Local Settings\Softwar
e\Microsoft\Windows\CurrentVersion\TrayNotify" /v "PastIconsStream"=-"

C:\Windows\System32>reg delete "HKEY_LOCAL_MACHINE\Software\Classes\Local Settin
gs\Software\Microsoft\Windows\CurrentVersion\TrayNotify" /v "PastIconsStream"=-"
 /f
Delete the registry value PastIconsStream=- /f (Yes/No)?

Thanks,

As I expected the value name is only PastIconsStream. So what's the reason for the =- in your code?

Code: Select all

reg delete "HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify" /v "PastIconsStream" /f
