Sign out instead of shutting down. This resets your user session and closes hidden processes.
Use Task Manager to end frozen apps. Press Ctrl+Shift+Esc to open it quickly.
Disable Fast Startup if apps freeze after booting.
Remove unused startup programs. Too many startup apps slow down your computer.
Empty your Recycle Bin and delete temporary files.
Uninstall programs you no longer use.
If a file won’t open, right-click it and choose “Open With” to pick a different program.
If a file is corrupted, try copying it to a different folder or drive.

Avoid random download sites that bundle extra software.
MSI installers are usually cleaner and harder to modify.
EXE installers can contain extra files or scripts.
Use Windows Defender to scan any installer before opening it.

If an installer asks for admin permission, make sure you trust it.
If an installer tries to install toolbars or extra programs, uncheck those boxes.
Restart the program or sign out to reset your session.
Check if the program is already running in the background.
Check your network cable or Wi-Fi connection.
Restart your router and modem.
Try forgetting and reconnecting to your Wi-Fi network.
Close background apps you aren’t using.
Restart your computer to clear memory.
Check your storage space — low disk space slows everything down.
Check if your speakers are plugged in or turned on.
Right-click the sound icon and choose “Troubleshoot sound problems.”
Make sure the printer is turned on and connected.
Restart the printer and your computer.
Check if the printer queue is stuck.
