BleachBit 1.10

BleachBit 1.10 includes important improvements for Windows 10, Firefox, Google Chrome, and more.


July 1, 2016: BleachBit 1.12 has been released.


These are the changes since version 1.8:

  • Clean passwords on Firefox version 32+.
  • Clean Google Chrome cookies for non-default profiles.

  • Specific to Linux

  • Specific to Windows
    • Show the User Access Control on Windows 10. This helps elevate BleachBit to administrator privileges. (reported by Mike L.).
    • Fix handling of Windows 10 in Winapp2.ini in DetectOS= .

    • Fix cleaning of MRU for Adobe Reader versions 5-11 (reported by Arkwright).

    • Fix error in same_partition(...) when Microsoft Office Starter 2010 is installed, which creates an inaccessible virtual drive Q: (reported by goingoin).

Known issues

Vacuuming new versions of Google Chrome or Chromium gives an error like Error in execution of <bleachbit.Command.Function instance at 0x02BF90D0> (bug ticket: LP#1545567, LP#1546716).

Root cause: In a recent update to Google Chrome and Chromium, they changed the file Thumbnails to a directory with the same name, and when BleachBit tries to vacuum Thumbnails, it fails because it is not an SQLite file.

Solutions for BleachBit version 1.10:

  • Use BleachBit 1.11.
  • Ignore the harmless error
  • Do not vacuum Google Chrome or Chromium
  • Manually delete the Thumbnails directory
  • Add the Thumbnails as a custom directory to be cleaned in BleachBit. Add the directory in the Preferences, and then check the box System - Custom.
  • Disable generation of Thumbnails in Google Chrome or Chromium

"Error opening file for writing"
c:\Program Files\BleachBit\-ctypes.pyd.
I have just donated $5.00 and uninstalled my old version and now I can't download the new version or 110.
How do I fix this?
HP Elite, Intel I7 860, standard HP box running at normal clock speed.

Please visit old downloads to find the previous version, 1.10.

I have never seen this error before and would like to know more about it. Also, what brand of antivirus do you use? Can you temporarily put it into game mode? Or temporarily disable it? Please let me know whether this helps and which brand you use.

Thank you for your donation!
