+# Uninstall a Windows Update by KB (PSWindowsUpdate)
+
+Minimal helper and examples to remove an installed Windows update by its **KB** number using the **PSWindowsUpdate** module.
+
+## Requirements
+- Run PowerShell **as Administrator**.
+- Module: `PSWindowsUpdate` (install if needed: `Install-Module PSWindowsUpdate -Scope CurrentUser`).
+- A reboot may be required after removal.
+
+## Quick commands (no wrapper)
+```powershell
+# List installed updates matching the KB
+Get-WindowsUpdate -IsInstalled -KBArticleID KB5028952
+
+# Uninstall (no auto-restart)
+Remove-WindowsUpdate -KBArticleID KB5028952 -NoRestart -Confirm:$false
+```
+
+## Script usage
+If you saved the wrapper as `Remove-KB.ps1`:
+```powershell
+# Example
+.\Remove-KB.ps1 -KB KB5028952 -NoRestart
+```
+
+## Notes
+- Some updates (especially **Servicing Stack Updates**) cannot be uninstalled.
+- If removal via PSWindowsUpdate fails for a cumulative update, find the exact package name and try DISM:
+  ```powershell
+  DISM /Online /Get-Packages
+  DISM /Online /Remove-Package /PackageName:<ExactName> /Quiet /NoRestart
+  ```
+- Logs: `C:\Windows\Logs\WindowsUpdate\windowsupdate.log` and `C:\Windows\Logs\CBS\CBS.log`.
