Managing Windows updates is a crucial task for maintaining the security and performance of your system. Windows provides several tools and commands to manage updates, both through the graphical user interface and command-line interfaces like CMD and PowerShell. This article will guide you on how to manage Windows updates using CMD and PowerShell, providing practical examples and commands.

Examples:

1. Checking for Updates via CMD:

   Although CMD does not have a direct command to check for updates, you can utilize Windows Update Agent API commands through the Windows Management Instrumentation Command-line (WMIC).

   wmic qfe list brief /format:table

   This command lists all installed updates on your Windows machine. However, it does not check for new updates.

2. Checking for Updates via PowerShell:

   PowerShell provides more robust capabilities for managing Windows updates. You can use the PSWindowsUpdate module to check for and install updates.

   First, you need to install the module:

   Install-Module -Name PSWindowsUpdate -Force

   Then, you can check for available updates:

   Get-WindowsUpdate

3. Installing Updates via PowerShell:

   After checking for updates, you can install them using:

   Install-WindowsUpdate -AcceptAll -AutoReboot

   This command installs all available updates and automatically reboots the system if necessary.

4. Scheduling Updates via Task Scheduler:

   You can use Task Scheduler to automate the process of checking and installing updates. Here’s how you can create a task using CMD:

   schtasks /create /tn "CheckForUpdates" /tr "powershell.exe -Command \"Get-WindowsUpdate | Install-WindowsUpdate -AcceptAll -AutoReboot\"" /sc daily /st 02:00

   This command schedules a task named "CheckForUpdates" to run daily at 2 AM.
