Quick Start

Overview

C Drive Cleaner is a lightweight Windows utility that frees space on the C drive without risky registry tweaks. Use it to clear temp files, Windows Update leftovers, crash dumps, and other system junk in a single pass.

Requirements

• Windows 10/11 64-bit
• Optional administrator permission when purging Windows Update caches
• A few hundred MB of free space for temporary cleanup work

4-step quick start

1. Download the latest build from cdrivecleaner.com and copy it to the Windows machine that needs cleanup.
2. Run the scan (elevate only if prompted) to detect update caches, temp folders, crash dumps, browser leftovers, and bulky system folders.
3. Review the checklist: every item shows the estimated space you can reclaim and the exact path before anything is removed.
4. Clean in one click: confirm the selection to delete, optionally create a restore point, and save the cleanup report for your records.

What we clean safely

• Windows Update caches and driver remnants
• %temp%, prefetch, crash dumps, and log piles
• Browser caches you opt in to clear
• Old installers and large forgotten directories on the C drive
• Startup-heavy apps highlighted for manual review

Safety guardrails

• Default read-only scan; nothing is deleted until you confirm
• Optional restore point before cleanup
• Excludes Desktop/Documents/Downloads by default
• Plays nicely with Windows Defender and existing corporate policies

Tips for teams

• Run weekly or before large Windows updates to avoid sudden disk pressure
• Use the portable build for helpdesk visits—no installation or background service required
• Archive the cleanup report so you can show how much space was reclaimed on each device
