Being an overnight Administrator I get a lot of low disk space alerts when drives hit their thresholds. Tonight I’m going to put an end to all this work. I wrote the following script to help automate the cleaning of C:\ drives or any drives that have a Windows operating system installed.
What Does this Script do?
- Clears all code off the screen
- Stops the Windows Update Service
- Deletes the contents of Windows Software Distribution
- Deletes the contents of windows temp folder
- Deletes files in users temp folder
- Deletes temporary internet files
- Cleans IIS logs
- Empties the Recycling Bin
- Starts Windows update service
- Outputs disk space before and after.

Now just open an elevated command prompt and run the this script.
Sample Output:
VT-MKERFOOT-W8 nbsp; DateTime -------- Thursday, December 04, 2014 5:00:15 MATTHEW Before: SystemName Drive Size (GB) FreeSpace (GB) PercentFree ---------- ----- --------- -------------- ----------- VT-MKERFOOT-W8 C: 223.2 41.8 18.7 % After: SystemName Drive Size (GB) FreeSpace (GB) PercentFree ---------- ----- --------- -------------- ----------- VT-MKERFOOT-W8 C: 223.2 45.9 20.5 % VT-MKERFOOT-W8 C: 223.2 29.2 13.1 % Transcript stopped, output file is C:\Windows\Temp\12-04-14-9.log
Note this would have cleaned up more files and given a long verbose string of files removed except I just ran this against my computer and it brought it from 18% free to 20% free(which was shown above). Now all you have to do is Download my script here!
