Output Microsoft Windows installed features to a file

Use PowerShell to output a list of installed features

This requires a couple steps. I ran this in Microsoft Windows 2012 R2. YMMV. I was in a rush and didn’t feel like figuring out why you have to do step 1.

1. Create a folder called log and text file called iis.log somewhere. I used C drive, so c:\log\iis.log. Or put it and call it whatever suits you. If you don’t pre-create it, the PS command will crash.
2. Open PowerShell as Admin and run this:

Get-WindowsFeature > C:\Logs\IIS.log

This is an example of the output you will get in the log file. I have scrolled down in the file so you can see items that are marked as installed.

...
[ ] DNS Server DNS Available
[ ] Fax Server Fax Available
[X] File and Storage Services FileAndStorage-Services Installed
 [ ] File and iSCSI Services File-Services Available
 [ ] File Server FS-FileServer Available
...

Very handy to see what is and what is not installed!
