+# Remove Windows Updates by KB (PowerShell)
+
+Uninstalls all installed Windows packages whose name matches a given **KB** via DISM PowerShell cmdlets.
+
+## Usage
+```powershell
+# List installed packages and filter by KB
+Get-WindowsPackage -Online | Where-Object { $_.PackageName -match "KB5032189" } | Select-Object PackageName, State, InstallTime
+```
+
+```powershell
+# Uninstall all packages matching the KB
+Remove-Package -KB "KB4589210"
+```
+
+## Notes & limitations
+MSU files: Remove-WindowsPackage removes packages in the image (.cab/package identities), not .msu directly
+SSUs can’t be uninstalled: Servicing Stack Updates modify the update stack and are not removable.
+After ResetBase: If you ran DISM /Online /Cleanup-Image /StartComponentCleanup /ResetBase, existing update packages can no longer be uninstalled.
