I was trying to find a good method/script to (remotely) get all the installed programs from a Windows 7 client. I didn’t want to use Remote Desktop or similar however, so it had to be a method that was unnoticeable for the user. I know that SCCM has its own software inventory, but I wanted a fast(er) way to check if version XXX of Office is installed on a client. The reason for this was mainly because there are (unfortunately) soooo many different Office installations throughout the whole University. (Also, it’s nice to have some clues about the client before SCCM starts using its magic). The script lists more than (Office) installations however, including other useful information as well. It is based on
and It basically queries the registry of a remote client and returns the installed software. Cheers to the author Anthony Howell!
This modified version also lists:
- Colored headings 🙂
- OS Name
- OS Version
- System Model
- Total Physical Memory
- Original Install Date
- Uptime/System Boot Time
- Current logged on user
Usage: .\get_programs_and_features.ps1 computername.
Here’s a screenshot with example output:
Fig 1. get_programs_and_features.ps1
The text in the screenshot is in Swedish, but it should be quite self explanatory 🙂
If you want to have a go yourself, the script looks like this (download link at the bottom):
