Normally when Google Chrome crashes or otherwise closes unexpectedly, it will prompt the user to ask if they want to re-open the previously open tabs. This can be annoying when Chrome is used for viewing a dashboard on an unattended device. These instructions will explain how to disable that prompt and automatically reopen the previously open page(s).
- In Windows, go to C:\Users\[your username]\AppData\Local\Google\Chrome\User Data\Default
- Right click "Preferences" file and click Open with. Select a text editor such as Notepad. Ctrl+F to find the following values, and change the value to:
- "exit_type":"none"
- "exited_cleanly":"true"1
- Save the file when finished.
- Now, right click the Preferences file and select Properties.
- Under "Attributes", enable "Read-only" and click OK.
After this change Chrome should automatically reopen closed pages after a crash.

1The "exited_cleanly" value may not exist, in which case it can be skipped.
