The summary.
LEARN THE SHORTCUT FOR YOUR SYSTEM SEARCH
It finds programs, settings and files from one place, and replaces hunting through menus entirely.
CLOSE A FROZEN PROGRAM WITH THE TASK MANAGER, NOT THE POWER BUTTON
Forcing power off risks corrupting whatever was open.
CHECK WHAT CAN NOTIFY YOU, AND WHAT SHOWS ON THE LOCK SCREEN
Messages and verification codes on a locked screen are readable by anyone nearby.
REGIONAL SETTINGS AFFECT MORE THAN YOU EXPECT
Spreadsheets interpret dates and numbers by them, so a file created under one setting is misread under another.
Agree one date format, and write dates as year-month-day in data and filenames.
CHECK WHETHER YOUR SYSTEM ALREADY DOES IT BEFORE INSTALLING ANYTHING
Screenshots, compression, disk usage, backup and a text editor are already there.
Use a plain text editor for anything that must contain no formatting.
NEVER RUN A COMMAND YOU DO NOT UNDERSTAND
There is no undo on the command line.
NEVER GRANT REMOTE ACCESS TO SOMEONE WHO CONTACTED YOU
Legitimate support does not call unprompted.
