How to install updates manually on Windows 11

To install updates (such as KB5066835) manually on Windows 11, open Settings > Windows Update and click “Check for updates.”
You can also download and install updates manually from the Microsoft Update Catalog website.
To manually install updates using commands, you can use either PowerShell or Command Prompt.

UPDATED 10/20/2025: On Windows 11, a cumulative update (or quality update) is a service patch that Microsoft rolls out proactively to fix bugs, enhance security, and improve system performance. Although updates download automatically through Windows Update, sometimes it may still be necessary to install a specific patch manually.

For instance, after a new installation of Windows 11 or if the computer hasn’t been connected to the internet for some time, issues may arise. If Windows Update isn’t working, you may need to install an update manually to resolve the issue. Or a specific driver needs an update, or you want to upgrade to a newer version of Windows.

Whatever the reason, Windows 11 offers multiple methods to update the system, including the Windows Update settings (recommended), manual download, Command Prompt, and PowerShell.

Microsoft offers three main types of updates (quality, optional, and feature updates). “Quality updates” are available monthly and include security and non-security fixes, improvements, and features (occasionally). “Optional updates” are not critical but necessary, such as drivers and product updates. Finally, “feature updates” are meant to upgrade the device to a newer version (for example, Windows 11 25H2).

In this guide, I will teach you the different methods to install updates on Windows 11 manually.

Install updates manually on Windows 11
Install updates manually from Microsoft Update Catalog on Windows 11
Install updates manually from Command Prompt on Windows 11
Install updates manually from PowerShell on Windows 11
Install optional updates on Windows 11
Install feature updates on Windows 11

Install updates manually on Windows 11

To install Windows 11 updates manually, follow these steps:

Open Settings on Windows 11.
Click on Windows Update.
(Optional) Check the “Get the latest updates as soon as they’re available” toggle switch to download updates before they roll out automatically to everyone.
Click the Check for updates button.
(Optional) Click the “Download and install” option to apply a preview of an upcoming update of Windows 11.

Quick note: Optional updates usually include non-security changes that Microsoft plans to release in the next Patch Tuesday rollout.
Click the Restart now button.

Once you complete the steps, if an update is available, it will download and install automatically on Windows 11.

Install updates manually from Microsoft Update Catalog on Windows 11

To download and install an update manually on Windows 11, follow these steps:

Open the Microsoft Update Catalog website.
Search for the knowledge base number of the update, for example, KB5066835.

Quick tip: You can check the update history tracker if you do not know the latest update knowledge base (KB) reference number.
Click the Download button.

Quick note: The page usually lists two versions, including ARM64 and x64. Unless you have an ARM-based device, you must download the x64 version of the cumulative update.
Click the link to download the “.msu” package corresponding to the KB number you intend to get.

Quick note: The download dialog will offer you two downloads, but you typically want to download the one that matches the KB number for the update you’re trying to install. The other KB number, “Checkpoint Update,” creates a baseline to establish a specific state on the system, which is part of a new differential updates mechanism on Windows 11 24H2 and 25H2.
Click the Close button.
Double-click the “.msu” file to launch the installer.
Click the Yes button to install the update.
Click the Restart now button.

After you complete the steps, the cumulative update will apply to Windows 11.

Install updates manually from Command Prompt on Windows 11

Windows 11 doesn’t have a Command Prompt tool to check and download updates. However, you can use commands to install the update packages manually.

To install Windows 11 updates with Command Prompt, follow these steps:

Open the Microsoft Update Catalog website.
Search for the knowledge base number of the update, for example, KB5066835.
Click the Download button to save the cumulative update package on your computer.
Click the link to download the “.msu” package.
Click the Close button.
Open Start.
Search for Command Prompt, right-click the top result, and select the Run as administrator option.
Type the following command to install a new update on Windows 11 and press Enter:
```
wusa c:\PATH\TO\UPDATE.msu /quiet /norestart
```
In the command, update the path with the location and name of the .msu package. This example installs the KB5066835 update:
```
wusa c:\Users\USERACCOUNT\Downloads\windows10.0-KB5066835-x64.msu /quiet /norestart
```
Type the following command to confirm the update was installed correctly and press Enter:
```
systeminfo | find "KB"
```
Type the following command to restart the device and press Enter:
```
shutdown /r /t 00
```

After you complete the steps, the quality update will install quietly, and the computer will continue to finish applying the changes on Windows 11.

Install updates manually from PowerShell on Windows 11

Alternatively, you can install a PowerShell module to download and update updates manually on Windows 11.

To install updates manually with PowerShell commands, follow these steps:

Open Start.
Search for PowerShell, right-click the top result, and select the Run as administrator option.
Type the following command to install the PowerShell module to update Windows 11 and press Enter:
```
Install-Module PSWindowsUpdate
```
Type “Y” to accept and press Enter.
Type “A” to install the module and press Enter.
Type the following command to allow scripts to run on PowerShell and press Enter:
```
Set-ExecutionPolicy RemoteSigned
```
Quick tip: If you’re getting a PowerShell error about a policy being defined at a more specific scope, then use the Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser command. You can learn more about the steps to change the execution policy to run scripts on PowerShell here.
Type the following command to import the installed module and press Enter:
```
Import-Module PSWindowsUpdate
```
Type the following command to check for Windows 11 updates with PowerShell and press Enter:
```
Get-WindowsUpdate
```
Type the following command to select, download, and install a specific update, and press Enter:
```
Install-WindowsUpdate -KBArticleID KBNUMBER
```
In the command, replace “KBNUMBER” with the Windows update number you want to install. This example downloads and applies the KB5066835 update for Microsoft Defender:
```
Install-WindowsUpdate -KBArticleID KB5066835 
```
Type “A” to confirm the installation and press Enter.
(Optional) Type the following command to download and install all available updates and press Enter:
```
Install-WindowsUpdate
```
Quick note: When using this command, you will be applying system updates and optional updates that may include driver updates.
Type “A” to confirm the installation and press Enter.
Type “Y” to confirm the restart and press Enter (if applicable).
(Optional) Type the following command to view a list of previously installed updates and press Enter:
```
Get-WUHistory
```

Once you complete the steps, the Windows 11 updates will download and install on your device.

Install optional updates on Windows 11

On Windows 11, while optional updates are not critical, they may be necessary for other functionalities. Typically, these updates are available for Microsoft and other products, feature updates, and third-party drivers (such as printers, cameras, network adapters, graphics cards, and Bluetooth peripherals).

To install optional updates manually on Windows 11, follow these steps:

Open Settings.
Click on Windows Update.
Click the Advanced options page.
Click the Optional updates setting under the “Additional options” section.
Click the category to reveal the available optional updates. For example, Driver updates.
Check the optional updates you want to install on Windows 11.
Click the “Download and install” button.

After you complete the steps, Windows Update will install the packages on your computer.

Install feature updates on Windows 11

Feature updates refer to new versions of Windows 11. These updates are optional, and you can install them manually. However, if the current release of Windows 11 is reaching the end of service, the update will install automatically.

To install a feature update manually on Windows 11, follow these steps:

Open Settings.
Click on Windows Update.
Click the “Check for updates” button (if applicable).
Click the “Download & Install” button.
Click the Restart now button.

Once you complete the steps, the current release of Windows 11 will be updated to the latest version, and depending on the feature update, the new version may require reinstallation.

In addition to Windows Update, you can install feature updates using the Installation Assistant or the official ISO file to perform an in-place upgrade. You can use a clean installation, which is sometimes the better option, as it can help fix existing issues and improve performance when upgrading with a fresh install.
