Install on Windows
To install BleachBit, first download the latest installation package for your system.
BleachBit is supported on Windows XP, 2003, Vista, 7, 8, 8.1, or 10 (32-bit or 64-bit).
Most Windows users want the standard installation. If you prefer to run in portably on a USB disk or on a system the administrators that prevents installation, use the portable installation.
Run the installer which has a name like BleachBit-1.6-setup.exe. Then, follow the prompts.
Verify the installer is from a verified publisher (Andrew Ziem).
Run the installer with the silent switch like this:
The switch is case-sensitive.
Download the package which has a name like BleachBit-1.6-portable.zip. Then use a standard unzip utility to unpack the file. Such a utility is included with Windows: just right click on the .zip file and choose Extract all files which creates a new folder.
Do not double click on the .zip file.
