Windows Updates are meant to keep your system safe, patched, and up to date. But sometimes they fail spectacularly. You may have seen this:
- Updates get stuck at 0% forever.
- Windows keeps retrying the same patch and failing.
- Error codes pop up that don’t seem to make sense.
- Standard troubleshooting (like the built-in troubleshooter or manual reset commands) doesn’t fix anything.
When you hit that wall, it’s frustrating. You either consider reinstalling Windows or leave your system vulnerable without updates. That’s where a neat little free tool called Update Fixer comes into play.
This portable utility promises to automatically clear caches, reset update services, and repair the essential components that Windows Update depends on. In this article, we’ll dive into what it is, how to use it, what risks to keep in mind, and when it might be worth trying.

1. Why Windows Updates Fail in the First Place
Before introducing the tool, let’s step back and understand why updates fail. Common causes include:
- Corrupt cache files: Windows stores update downloads in the SoftwareDistribution and Catroot2 folders. If these get corrupted, updates won’t install.
- Disabled services: Essential services like Windows Update, BITS (Background Intelligent Transfer Service), or Cryptographic Services may stop working.
- Third-party software interference: Security tools, firewalls, or “update blocker” apps can disable update services in the background.
- Damaged system files: Core Windows files that updates rely on may be missing or corrupted.
- Network/registry misconfigurations: Sometimes even the hosts file or registry policies can block update servers.
Normally, you can fix these by manually running commands, deleting folders, and restarting services — but that’s tedious, and many users aren’t comfortable doing it.
2. What Is Update Fixer?
Update Fixer is a lightweight, portable tool created by an independent developer. Portable means:
- You don’t install it.
- You just download and run the executable.
- It makes targeted repairs to Windows Update components.
The developer first shared it on Reddit, where users struggling with updates started testing it. While not an official Microsoft product, it essentially automates the manual troubleshooting steps many technicians already know.
3. Where to Download It
You can find Update Fixer on its official GitHub repository or the developer’s shared page. (⚠️ Always download from the official source to avoid tampered copies.)

Because this is a newer tool, Windows SmartScreen may warn you the first time you run it, saying it’s from an unknown publisher. That doesn’t necessarily mean it’s unsafe — it just hasn’t been certified yet.

4. Things to Do Before Running the Tool
It’s tempting to just double-click and hope it fixes everything, but let’s prepare properly:
- Create a System Restore Point: This way, if something goes wrong, you can roll back your system. Update Fixer itself even recommends this.
- Back up important files: Always a good idea before system changes.
- Close background apps: Free up resources and reduce conflicts.
- Run as Administrator: The tool needs elevated privileges to reset services.
So far, we’ve done a good job getting ready. Now let’s move on to the actual steps.
5. Step-by-Step: How to Use Update Fixer
Here’s exactly how you’d use it:
- Download the portable executable.
- Double-click it. If SmartScreen warns you, click “More Info” → “Run Anyway.”
- Approve the UAC (User Account Control) prompt.
- The Update Fixer window will open.
- Click Analyze to let it scan your system.
- Choose the recommended fix or select advanced fixes manually.
- Click Fix Windows Update and wait (1–5 minutes).
- Restart your computer when prompted.
That’s it — no command typing, no manual service resets.
6. Options and Fixes It Provides
This is where Update Fixer stands out. It doesn’t just reset one thing; it gives you multiple repair options. Some include:
- Clear and reset delivery files & key folders (the main recommended fix).
- Clear temporary files.
- Reset Windows Hosts file (useful if malware modified it).
- Re-enable Windows Update settings.
- Disable software that blocks Windows Updates.
- Restart/re-enable services:
- Windows Update
- BITS (Background Intelligent Transfer Service)
- Cryptographic Services
- Windows Installer
- Windows Modules Installer
- Update Orchestrator
In short, it resets almost every moving part that could break updates.
7. What to Expect During the Process
When you hit Fix Windows Update, here’s what happens:
- A script runs in the background, clearing caches and restarting services.
- You might see a Command Prompt window flash.
- The process can take 2–5 minutes, depending on how many options you selected.
- When finished, you’ll be prompted to reboot.
After restarting, another command prompt may appear briefly to complete the reset — then it closes automatically.
8. After Running Update Fixer: What Next?
Once your PC reboots:
- Open Windows Update from Settings.
- Click Check for Updates.
- If the tool worked, updates should download and install normally.
If not, you can try running Update Fixer again with additional repair options checked.
9. Pros and Cons of Using Update Fixer
No tool is perfect. Let’s weigh it fairly.
Pros:

- Easy to use even for non-technical users.
Cons:
- Not officially supported by Microsoft.
