 ### Script Won't Run
 
-If your PowerShell session is running in **Constrained Language Mode**, some scripts and commands may fail to execute. To check the current language mode, run:
+If you run WinUtil and get the error:
-```powershell
-$ExecutionContext.SessionState.LanguageMode
-```
-If it returns `ConstrainedLanguage`, you may need to switch to `FullLanguage` mode or run the script in a session with administrative privileges. Be aware that some security policies may enforce Constrained Language Mode, especially in corporate or managed environments.
 
-**If the download fails**:
+`"WinUtil is unable to run on your system, powershell execution is restricted by security policies,"`
 
-1. Try the direct GitHub link:
+this means that your PowerShell session is in **Constrained Language Mode**, which prevents WinUtil from running.
-
-```powershell
-irm https://github.com/ChrisTitusTech/Winutil/releases/latest/download/Winutil.ps1 | iex
-```

-2. Force TLS 1.2:
-
-```powershell
-[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
-irm "https://christitus.com/win" | iex
-```
-
-> [!NOTE]
-> On Windows 11, you usually do not need the TLS 1.2 command. Use it only if you encounter download or security protocol errors.
-
-### Execution Policy Error
-
-If you see an execution policy error when running the downloaded script, you can allow the current session to run unsigned scripts with this command:
-
-```powershell
-Set-ExecutionPolicy Unrestricted -Scope Process -Force
-irm "https://christitus.com/win" | iex
-```
-
-This only changes the policy for the current PowerShell process and is safe for one-off runs.
-
-### Interface Doesn't Appear
-
-If Winutil downloads, but the GUI does not open or appear, try these steps:
-
-1. Check if your antivirus or Windows Defender is blocking the script — add an exclusion if necessary.
-2. Ensure you launched PowerShell / Terminal as **Administrator**.
-3. Close and reopen PowerShell, then run the launch command again.
-4. If the script still doesn't show, try running the script in a visible PowerShell window (avoid background/silent shells) to observe output and errors.
