    Hello.  A few weeks ago I noticed a file named `debug.log` begin to appear in a few Windows folders (Win 10, x64).  How can I go about determining the origin, and preventing them from being created?  

    The contents of the file are log entries of this form:

        [0810/181603.876:ERROR:crash_report_database_win.cc(427)] unexpected header
        [0810/182501.651:ERROR:crash_report_database_win.cc(427)] unexpected header
        [0810/192930.630:ERROR:crash_report_database_win.cc(427)] unexpected header

    Each file typically only has a handful of such lines (1-5).  There are several of these debug.log files on my computer, in seemingly random folders.

    I have found one way to reproduce the issue.  On my computer is a Google Sheets file shop.gsheet.  Whenever I open this file (the file opens in Google Chrome), the debug.log file is created.  If I copy this Google Sheets file to another folder and open it, a new debug.log file is created in that new folder.   But this isn't the only way debug.log files are being created.  The mysterious log files exit in folders that do *not* possess Google Sheets files.  One such log file is in my folder D:\temp (which has no Google Sheets files, or any Google-type files at all), and a few new entries get logged to that file every day.  If I delete it, the file returns within a day.

    Thanks in advance.

    that looks like the debug log written by chrome, possibly by other programs too.
    debug.log file getting created each time when opening a html file using Chrome
    When this is not done by Chrome, you could use a file filter in ProcessMonitor to find which process is writing these files

    Hi cagross99,

    You could perform a clean boot to avoid the effects of software.

    https://support.microsoft.com/en-us/help/929135/how-to-perform-a-clean-boot-in-windows

    Some people met the same error before. You could completely uninstall Chrome and install the latest version to check.

    Also try to create a new user account to check.

    Hope it will be helpful to you

    @Carl I tried a clean boot, the issue was still there.  At least, I can still consistently re-create the issue using the method I described earlier.

    I tried to uninstall Chrome, but was met with an error.  Windows could not find the installer file (screenshot).  The Google link you posted has instructions on how to carry out a clean removal of Chrome (using their own uninstaller application).  I'll need a few days to carry out that test though.  When I do so, I'll report back here.

    @EckiS thanks for that suggestion about ProcessMonitor.  If my Chrome troubleshooting comes up empty, I'll try this.

    @Carl, I was able to re-install Chrome using the link you provided.  That seems to have worked.  At least, I can no longer re-create the issue as before.  Let's consider this resolved, thanks!
