Windows 10/11 disk cleaner software for freeing up more space

The built-in disk cleanup tool does not do much help. I tested on Windows 11 and Windows 10, lol

The "C drive red" scenario is a classic, and you're right—once the built-in Windows tools stop making a difference, you need a new strategy. Since standard cleanup didn't work, the problem is likely not just ordinary temporary files, but rather specific large items the default tools overlook, like old Windows Update caches, hibernation files, or massive folders you haven't noticed.

Since you are down to less than 20GB, you are in a risky zone. Windows needs free space to update and run page files. You should also know that Compressing your C: drive or using Compact OS (features in tools like DISM++) is risky on an SSD that full—it can cause performance issues.

If after all this you still can't find the best disk cleaner software for Windows 11, the most reliable free method is a Fresh Start.

1. Back up your personal files to an external drive (or OneDrive/Google Drive).

2. Go to Settings > System> Recovery.

3. Click "Reset this PC" and choose "Remove everything."

4. Removing all hidden junk and restoring your full 256GB when prompted, turn ON "Clean drives." This performs a full wipe and reinstall of Windows.

If your C drive is showing red and you're down to less than 20GB free on a 256GB SSD, and the built-in Windows Disk Cleanup hasn't made enough difference, you'll need a more powerful disk cleaner software for Windows 11 that can deeply clean your system.
