+ Silent Uninstaller (PowerShell)
+
+Removes installed apps by name using data from Windows **Uninstall** registry keys.  
+Supports **MSI** (`msiexec /X {GUID}`) and **EXE** uninstallers with a custom silent switch.
+
+## What it does
+- Searches in:
+  - `HKCU\Software\...\Uninstall`
+  - `HKLM\Software\...\Uninstall`
+  - `HKLM\Software\Wow6432Node\...\Uninstall`
+- Detects MSI vs EXE uninstallers and runs them silently.
+- Logs each action to `C:\Windows\temp\uninstall.log`.
+
+## Usage
+```powershell
+# Syntax
+Uninstall -AppName "<partial or full DisplayName>" [-Arg "<silent-args>"]
+
+# Examples
+Uninstall -AppName "Firefox"   -Arg "-ms"
+Uninstall -AppName "TeamViewer"      # uses default /S
+Uninstall -AppName "AnyDesk"
+```
+
+⚠️ Notes
+
+- Run PowerShell **as Administrator**.  
+- `-AppName` performs a **contains** match on `DisplayName` (may uninstall multiple apps if names overlap).  
+- Silent switches vary by vendor; override with **`-Arg`** if needed.  
+- MSI uninstalls run with `REBOOT=ReallySuppress /qn`, but a reboot may still be required.
