Function Start-Cleanup {
<# 
.SYNOPSIS
   Automate cleaning up a C:\ drive with low disk space

.DESCRIPTION
   Cleans the C: drive's Window Temperary files, Windows SoftwareDistribution folder, 
   the local users Temperary folder, IIS logs(if applicable) and empties the recycling bin. 
   All deleted files will go into a log transcript in $env:TEMP. By default this 
   script leaves files that are newer than 7 days old however this variable can be edited.

.EXAMPLE
   PS C:\> .\Start-Cleanup.ps1
   Save the file to your hard drive with a .PS1 extention and run the file from an elavated PowerShell prompt.

.NOTES
   This script will typically clean up anywhere from 1GB up to 15GB of space from a C: drive.

Hi, thanks for the script. It is really great. :)
I wanted to know if you can lend me a hand with something:

I want to run this function (only the Start-Cleanup function. Not the others since I don't want to mess with WinSxS) against several remote computers. Do you know how I can go about this? (Invoke-.command does not seem to do the trick here)

And I would also like to run it as a schedule task. So that the remote computers get cleaned every x days.
Could you me help out with this?

Thanks in advance

how do you deploy a schedule task if you can create one. Are you using sccm or other deployment tools? I can help you to make a schedule task.
