- 1Have a "guest account" on your PC, and use a password on your own account. When your guest says "Can I check my Facebook?" you simply switch user (or log out) and give them the guest account to play with. You'll find it under Control Panel -> Users / Accounts -> Enable Guest Account on Windows (all versions of Windows are slightly different, so click around!)
- 2Make the browser on your guest account forget where it's been when it's closed. On Firefox, it's Preferences -> Privacy -> "Firefox will" -> "not remember". Check the "don't track" box, while you're there.
- 3If you can't log out or switch user sometimes, have a spare browser handy. If you prefer Firefox, install Chrome for your guests, and vice versa. When your mum wants to check her Gmail, simply start your spare browser and leave it to her! Leave the link to your guest browser prominently on the desktop or in the task bar in case your PC is hijacked when you're out of the room.
- Set your guest browser on your account to forget history and not track, like your guest account
- Keep your own history clean and use private browsing (Ctrl+Shift+P on Firefox) when you can.
- Ctrl + Alt + L will lock the screen while you're out of the room - if there's a password on your account, your mates can't "just check their email" while you're not looking.
- If you have one mate who's always on your PC, give them their own account. It will make them feel special, and they can Customize it how they like :)
- This advice won't help against small children with sticky fingers, or cats who like to sit on the keyboard.
- Go back into the guest account and periodically remove naughty pics, your friends' private email attachment docs and any malware.
- If your friends aren't computer savvy, they're likely to click on anything on a website with a flashing link. Make sure your firewall and antivirus are up to date!
