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.
