Use the Windows Task manager in Windows 10 to disable programs that start up automatically from slowing down the boot-up process. Right-click on the Task Bar along the bottom of the screen, then select Task Manager. When the Task Manager opens, you might have to click on More Details in the lower left. Then click on the tab across the top, labeled Startup. Here you can disable things that automatically load while Windows starts up. Things you disable are not uninstalled, making it easy to re-enable them if you get over-zealous. You will have to restart the computer for these changes to take effect.

Now, you should be able to highlight a block of text, click on the name of your application (up by the black Apple logo) and look under Services for Summarize. It may not be perfect but it is worth a try.

When nothing else turns off your computer, you can always press the power button for five seconds until all lights go off, then turn it back on. It may take a bit longer to boot up, since it’s checking files and such. If this becomes a regular occurrence, though, there is likely something else wrong and you should have it checked out.
