Windows computers need at least 100 MB of free space

👍 This rule of thumb applies to computers running Windows 11, Windows 10, Windows 8, Windows 7, Windows Vista and Windows XP.

🦖 Are you still running Windows 7? That’s dangerous! It doesn’t get patch updates. You’re making it easy for hackers to break into your computer.

🖥️ However, even 100 MB may not be enough. Your computer needs at least 10% of free space available to install updates, Dell reports.

Macs need at least 5GB of free space

💻 Your hard drive should have anywhere from 5% to 15% of its capacity freed up.

📹 The exact percentage depends on how much you’re doing on your computer. If you love gaming or editing videos, go with 15%.

😊 If you mainly browse the web and rarely download files or apps, 5% may be OK.
