How can I do a disk cleanup on Windows 11?

What NOT to delete (Keep these UNCHECKED)

❌ Windows ESD installation files

❌ Anything with "system" in the name unless you're certain

❌ Program files folders manually

❌ Windows folder contents directly

For Your 256GB SSD Specifically:

1. Disable Hibernation (if you don't use it):

Open Command Prompt as Administrator

Type: powercfg.exe /hibernate off

This can free 4-8GB (size of your RAM)

2. Move files to external storage:

Videos, photos, old documents

Use OneDrive/Google Drive for cloud storage

3. Reduce System Restore space:

Search "Create a restore point"

Click Configure → Reduce max usage to 5-10%
