wuShowHide settings deleted by BleachBit

Do you have Winapp2.ini installed in BleachBit? Do you have many options checked?

I found that wushowhide.diagcab unpacked itself to C:\Windows\Temp\SDIAG_df79bbb8-a2d3-42de-a7a0-ec4fb65250c8, where there were files including PowerShell scripts, XML files, and a DLL. It shows in Windows Task Manager as process name msdt.exe (Diagnostics Troubleshooting Wizard). If you are technically inclined, you can trace wushowhide using Process Monitor (procmon): it may do its work under the msdt.exe or a built-in Windows process.

To figure out which option in BleachBit affects wushowhide, try disabling Windows Updates under the Microsoft Windows category in Winapp2, and in BleachBit's native System cleaner, disable Update Uninstallers.

If that does not work, you might disable the whole Microsoft Windows cleaner (from Winapp2.ini) and Windows Explorer.
