Right click any file of that type, choose Get Info, pick your favorite app under ‘Open with’, then click ‘Change All’ and confirm so every file of that kind uses that app from now on, and repeat once more after the next app update if it ever resets the default again.

Create a local account in Settings under Accounts and Family and other users, then sign in with that account and in every Microsoft app that pops up a sign in box, look for the tiny ‘No’ or ‘Skip for now’ link, and turn off ‘Let Microsoft suggest ways to finish setting up your device’ in Privacy and security so these prompts stop appearing after each restart.

Open Settings, go to Battery, then Battery Health and charging and turn on Optimized Battery Charging, then go back and tap Battery Usage to spot any app that is suddenly at the top of the list and switch off Background App Refresh just for that app in Settings so it cannot quietly eat your battery all day.

Close Chrome, then open Task Manager and end every process that still says Chrome or Google, even if the browser looks closed. Next, reopen Chrome, type chrome://extensions in the address bar, and turn every extension off, then turn them back on one by one until you find the one that triggers the fan and high CPU jump in Task Manager.

Before bed, swipe down to open Control Center and make a quick three step routine: turn on Low Power Mode, turn off Bluetooth if you are not using a watch or earbuds, and tap the Focus icon to enable Sleep or Do Not Disturb so apps stop waking the phone. Then, once, go to Settings, Battery, tap Battery Health & Charging and switch on Optimized Charging, and in Battery usage scroll to see which app is at the top overnight; for any social or shopping app near the top, go into its settings and turn off Background App Refresh so it cannot run all night.

Instead of randomly deleting files, start by clicking the Apple menu, choosing About This Mac, then Storage, and then Manage. Use the Recommendations panel to first empty Trash automatically and remove large, already watched TV shows and movies, then switch to the Documents section and sort by Large Files; only delete items you recognize like old installers, zipped folders, or duplicate downloads. As a pro move, open your Downloads folder in Finder, press Command + J, sort by Date Added, and quickly delete anything older than three months that you clearly no longer need.
