Freeing Up Disk Space with the Disk Cleanup
Utility
If you need to free up disk space on your unit, you can use the Windows
Disk Cleanup utility.
With this utility, you can clear files such as the Internet temporary files, files
from the Recycle bin, or even files that you no longer need from the
previous installation. The files from the previous installation are stored in
the Windows.old folder that Windows creates automatically when you
perform a refresh operation.To avoid losing data, you may want to back up
files from this folder before removing it.
To free up disk space with the Disk Cleanup utility:
1. If desired, back up your data.
Note: If you want to have a look at the content of the Windows.old folder
containing files of the previous installation, go to the root of the C drive
(Windows (C:)). If you do not see the Windows.old folder, it means no
refresh operation has ever been performed on your unit.
2. From the main window, tap the System Settings button.
