Resetting your laptop is one of the most powerful munitions you’ve got in your troubleshooting armory. It puts your Windows, macOS, or Chrome OS computer back to the state it was in when you first got it home from the store, and that means you’ve got none of the clutter, or bugs, that may have built up in the time since.
Thankfully, the process is much easier than it used to be. Microsoft, Apple, and Google have put tools for the job right inside their operating systems, while applications have come to rely more and more on the cloud, so your important data is most likely already backed up somewhere online ready to be redownloaded.
