You can safely remove old Windows update files from your C drive using built-in tools like Disk Cleanup, Storage Sense, or by manually clearing the update cache folder. This frees up space without affecting your personal files, though it prevents rolling back to older Windows versions.**
## 🛠️ Methods to Remove Old Windows Update Files
### 1. **Disk Cleanup**
- Open **Start Menu** → search **Disk Cleanup** → run it.
- Select **C drive** → click **Clean up system files**.
- Check **Windows Update Cleanup** (and optionally **Delivery Optimization Files**).
- Click **OK** → **Delete Files**.
- This is the most reliable method for Windows 10/11.
### 2. **Storage Sense / Temporary Files**
- Go to **Settings → System → Storage → Temporary files**.
- Select **Windows Update Cleanup** and **Delivery Optimization Files**.
- Click **Remove files**.
- Works best on Windows 11 and newer builds of Windows 10.
### 3. **Manual Cache Deletion**
- Press `Win + R`, type `services.msc`, stop **Windows Update service**.
- Navigate to `C:\Windows\SoftwareDistribution\` folder.
- Delete all files inside.
- Restart the **Windows Update service**.
- This forces Windows to re-download updates fresh. [How-To Geek](https://www.howtogeek.com/how-to-clear-your-update-cache-on-windows-11-and-10/)
