General questions

Section titled “General questions”

Is Windows 10 still supported?

How do I uninstall WinUtil?

Section titled “How do I uninstall WinUtil?”

You do not need to uninstall WinUtil. Because it runs as a PowerShell script, it is loaded into memory only while it is open. Once you close it, it is removed from memory and does not remain installed on your system.

Is WinUtil safe to use?

Section titled “Is WinUtil safe to use?”

Yes, WinUtil is open source, and the code is publicly available on GitHub. Thousands of users run it daily. However, like any system modification tool, you should:

  • Run it as Administrator (required)
  • Create a restore point before major changes
  • Understand what tweaks you’re applying
  • Run only from the official source

Do I need to keep running WinUtil?

Section titled “Do I need to keep running WinUtil?”

No. Once you’ve applied tweaks or installed applications, you can close WinUtil. Changes persist after closing. You only need to run WinUtil again when you want to make additional changes or undo tweaks.

Does WinUtil require internet access?

Section titled “Does WinUtil require internet access?”
  • For downloading: Yes, installing applications requires the internet
  • For tweaks: No, most tweaks work offline
  • Initial run: Yes, to run the latest script

Installation & running

Section titled “Installation & running”

How do I run WinUtil?

  2. Run: irm "https://christitus.com/win" | iex
  3. Wait for the GUI to appear

Why do I need Administrator rights?

The script won’t download. What do I do?

Section titled “The script won’t download. What do I do?”

Try these solutions in order:

  1. Use the direct GitHub link:

    Terminal window
    irm https://github.com/ChrisTitusTech/winutil/releases/latest/download/Winutil.ps1 | iex

  2. Force TLS 1.2:

    Terminal window
    [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
    irm "https://christitus.com/win" | iex

  3. Change DNS to Cloudflare (1.1.1.1) or Google (8.8.8.8)

  4. Use a VPN if GitHub is blocked in your region

I get an “Execution Policy” error. How do I fix it?

Section titled “I get an “Execution Policy” error. How do I fix it?”

Run this command first to allow script execution:

This only affects the current PowerShell session and is safe.
