Getting Installed softwares name and version using "Reg Query"

can anyone please help me to find out the display name and version of all installed softwares of a machine by using "Reg Query"?

if we use "/s" option with "reg query" then we will get all subkeys and value names recursively, but i need only display name and display version of each and every software. .

Solution

  • exceute the below command "REG QUERY HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall /s"

    split the output of above command using "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall\" to get the array of strings. Now parse the each string for software display name and version.

    Regular expressions for getting displayname and version are:

    Displayname: "(.*)" + "DisplayName" + @"\s+REG_SZ\s+(.*)\s"

    Displayversion: "(.*)" + "DisplayVersion" + @"\s+REG_SZ\s+(.*)\s"
