Have you upgraded to Windows 7? If not, then you should. Once you upgrade to Windows 7 you will find that there is a huge file (over 100GB) that contains your old Windows system. I upgraded from Vista and the file was located in the C: drive and ate up a big chunk of hard disk space. Before you remove this huge file make sure you make all your recovery disks and also back up your files. Here’s how to remove the file safely.
1. Run Disk Cleanup from the start menu
2. The Windows.old file is located on the C: drive, click ok
3. You won’t find the option here until you click on “Clean up system file“
4. Again select C: drive
5. Here you will be able to select “Previous Windows installations(s)“
Now you should see some extra disk space and maybe even a bit improvement on system performance since you got rid of thousands of files that you don’t need anymore.
