Windows 8 Consumer Preview has been launched and I wanted to test it out. So I downloaded Windows 8 Consumer Preview Setup from

But then I found that Win 8 is also available in .iso format. So I stopped the setup and started downloading the iso file. However, the Windows 8 setup had already allotted 2.8 GB of disk space. I want to free that space. What should I do?

I ran disk clean-up but nothing happened.

Where does the setup keeps the downloaded files?

While it is downloading the files will be stored in %AppData%\Local\Microsoft\Websetup

And after the download before the install you can find them in C:\WindowsESD

I finished the install, but the files were still there in the C:\WindowsESD folder. This was on Windows 7. Just FYI. – Phanindra K Jul 23 '12 at 3:11

The downloaded windows installation is stored here:

This directory appears to be where the final Windows 8 installer places them. – JamesGecko Nov 20 '12 at 3:01

The FAQ for the Win8 CP mentions that it will download an installer optimized for your device. It also says that you can't uninstall it; you have to reinstall your original OS when you finish with the Preview. Just FYI.

I'm running the Windows 8 Consumer Preview Setup, watching it in Process Explorer. It appears to be using the following directory:


However, I'm getting an error when I get to the download step, so I'm not seeing where the actual installer files are saved.

Got it going on a different system. There's a Downloads subdirectory of the one I listed above. On my system there's now a 2GB+ file in there. – Geoff Duke Feb 29 '12 at 19:20

I don't know where the files are, but you could try WinDirStat to look for folders containing about 2.8 GB that you don't think were there before and don't look like something important.

I'd suggest looking at the root of the system drive, or somewhere with the word "tmp", "temp" or "install" in the name, quite possibly a hidden folder.

using WinDirStat...I found mine here (I stopped it before it completed to get the ISO)

C:\Users\"YOUR USER NAME"\AppData\Local\Microsoft\WebSetup\Download

obviously you need your username
