Generate a list of installed programs with PowerShell code

The Tip of the Night for August 29, 2018, explained how to run a Windows command to get a list of software installed on your PC. Subsequent experience has shown that the wmic command doesn't generate a complete list. You should have better luck with the PowerShell posted here by FelixGill.

Open PowerShell ISE, and in the console put in this code:

Get-ItemProperty HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion, Publisher, InstallDate | Format-Table –AutoSize

Then simply press enter. A list will be generated showing the name of programs you've installed, the version, publisher and install date.

Script to Copy Data and Rename It

A very simple Powershell script can be used to copy files from one folder and save them renamed in another folder.

The simple command, 'Copy-Item' will accomplish this task. Simple follow it by the path to the source file name and the new file name.

So a script like this:

Copy-Item "C:\FooFolder\Picture1.png" "C:\FooFolder\NewFolder\ScreenGrab1.png" Copy-Item "C:\FooFolder\Picture2.png" "C:\FooFolder\NewFolder\ScreenGrab2.png" Copy-Item "C:\FooFolder\Picture3.png" "C:\FooFolder\NewFolder\ScreenGrab3.png" Copy-Item "C:\FooFolder\Picture4.png" "C:\FooFolder\NewFolder\ScreenGrab4.png"

. . . will copy the .png files to the new location. 'New Folder', renamed as 'ScreenGrab1.png'; 'ScreenGrab2.png'; 'ScreenGrab3.png'; and 'ScreenGrab3.png'
