how to get all installed software in windows machine using 'Get-ItemProperty' from powershell?

Question

I tried this in my script. Get-ItemProperty HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall* | Select-Object DisplayName | Format-Table -AutoSize >>as.txt

Output: 'Get-ItemProperty' is not recognized as an internal or external command, operable program or batch file.

If you have an x64 version of Windows, perhaps something like this single line batch file would help:

@%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe -NoProfile "$MyProgs = Get-ItemProperty 'HKLM:SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\*'; $MyProgs += Get-ItemProperty 'HKLM:SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\*'; $MyProgs.DisplayName | Sort-Object -Unique" 1>"as.txt"
