This Simple Trick Recovered 19 GB Free Disk Space On My Windows Installation :)

Windows 7 installation on my dual boot Apple iMac started complaining about low disk-space and I was in a fix whether to clean-format the Windows partition or go for selective uninstallation of applications and data I no longer need. I fired-up my favourite disk space analyzer tool - Folder Size and voila, I now know what I need to do to quickly recover GB's of free disk-space without removing anything.

Windows Free Disk Recovery

Folder-Size scan showed that c:\windows\Installer folder occupied 9.48GB disk-space, this is a system folder and you cannot delete it so I decided to use the Windows Disk Cleanup tool to let it take care of it.

With years of usage Microsoft Windows tend to accumulate Update files, installer cache and memory-dumps which can occupy GB's of disk-space on your computer. Luckily, Microsoft provides a free utility with Windows allowing users to quickly and easily claim-back this disk-space.

How to use Windows Disk Cleanup utility:

  • To start, navigate to - Start->Search box->type 'Disk Cleanup'->select 'Disk Cleanup' from results.
  • Select the drive that you want to clean up, and then select OK.
  • Disk Cleanup
  • After the Scan, you will see how much disk-space can be recovered by the utility. You can select/de-select options from the list to choose which data you want to keep and which you don't. In my case 19GB disk-space will get recovered by Disk-Cleanup utility, majority (~12GB to be precise) of this was occupied by Windows Memory Dumps.
  • Disk Cleanup Space
  • Click OK and the utility will Warn you of Permanent data deletion.
  • Disk Cleanup Warning
  • If you clicked OK, the utility will go ahead and you would have recovered free-space on your disk.


Welcome to the internet... !! I did this when I was 10 years old.

Does that make it less of an utility worth discussing?
