Manually installing Windows updates can be achieved in three ways. First, visit Microsoft Update Catalog, search for the KB number or find and download the version suitable for the system by product category (difficult to x86 and x64), and then double-click to install; second, if there is an update file (.msu format), you can directly double-click to run Windows Update Standalone Installer to install, and restart according to the prompts; finally, advanced users can use the command prompt to run the DISM tool as an administrator, and enter the "wusa .msu /quiet /norestart" command to install silently. Either way, you need to make sure that the system architecture and Windows version match, and you can confirm the update status through the "Settings" or "wmic qfe list" command after installation.

Manually installing Windows updates can be necessary for a variety of reasons—maybe your system isn't picking them up automatically, or you're dealing with a specific issue that needs a particular patch. Whatever the case, it's not too hard to do manually, and it gives you more control over what gets installed.

Using Microsoft Update Catalog

One of the most direct ways to install updates manually is through the Microsoft Update Catalog . This site lets you search for specific updates or browser by product and classification.

• Go to Microsoft Update Catalog
• Search using the KB number (like KB5034441) or describe what you need
• Download the correct version for your system (x86 vs x64 matters here)
• Once downloaded, double-click the file and follow the prompts

It helps to know whether your system is 32-bit or 64-bit before downloading anything. You can check this in Settings > System > About.

Installing from an Update File

If someone else already downloaded the update file or you saved one from a previous attempt, you can install it directly without going online again.

• Locate the .msu file on your computer
• Double-click it—it should open the Windows Update Standalone Installer
• Click “Yes” when prompted and wait for the installation to complete
• Restart your computer if needed

Sometimes, especially after major issues, Microsoft releases standalone packages for known problems. These are often shared on forums or support pages and can be handy to have around.

Using Command Prompt for Advanced Users

For those comfortable with the command line, Windows has a built-in tool called DISM (Deployment Imaging Service and Management Tool) that can help install update packages.

Here's a basic flow:

• Open Command Prompt as Administrator
• Navigate to the folder containing the update file
• Run: wusa <filename>.msu /quiet /norestart</filename>

This method is useful if you're scripting or managing multiple machines. Just make sure the update is compatible with your OS version—trying to install the wrong one won't work and may give confusing error messages.

Checking Installed Updates

After installing any manual updates, it's good practice to confirm they were applied correctly.

• Go to Settings > Windows Update > View update history
• Or type wmic qfe list in Command Prompt for a full list

If something went wrong during installation, you'll usually see an error code. Searching that code online can often point you towards a fix.

Basically, manual installation boils down to knowing which update you need, getting the right file, and applying it properly. It's not complicated, but it does require a bit of attention to detail—especially matching your system architecture and Windows version.
