How to Repair Windows 10 on Another Computer

If you're dealing with a computer that has a malfunctioning or broken version of Windows 10, you might be wondering if there's a way to repair it without physically being in front of it. As a tech enthusiast, I’ve encountered this issue many times, and I’ve learned that it's entirely possible to repair Windows 10 remotely. In this article, I’ll walk you through the process of repairing Windows 10 on another computer, including the tools you’ll need and tips for troubleshooting effectively.

1. Understanding the Need for Remote Windows 10 Repair

There are a variety of reasons you might want to repair Windows 10 on another computer. It could be a friend’s PC, a relative’s laptop, or even a business computer that needs fixing but isn't physically accessible. In my experience, remote repair can save a lot of time and effort, and it's often more efficient than trying to walk someone through the repair process over the phone.

1.1 The Benefits of Remote Repair

Remote repair allows you to fix issues without being physically present, which can be extremely helpful if the device is located far away or you simply don’t have the time to travel. Additionally, many of the common Windows 10 issues can be resolved remotely, including system crashes, slow performance, and even software conflicts. Plus, with the right tools, you can access the computer from anywhere in the world.

2. Tools You’ll Need to Repair Windows 10 Remotely

Before starting the repair process, you need to gather the necessary tools. I’ve used a combination of software and built-in Windows features to troubleshoot and fix remote systems. Here's what you’ll need:

2.1 Remote Desktop Connection

One of the most reliable tools for remotely accessing another Windows 10 computer is Remote Desktop Connection. This built-in feature allows you to connect to another computer as if you were sitting right in front of it. To use this, both computers need to have Windows 10 Pro or higher, and you’ll need to enable Remote Desktop on the target machine. Once set up, you can log into the computer and perform repairs, install updates, or adjust settings.

2.2 Third-Party Remote Access Software

If Remote Desktop isn't an option or you prefer a more flexible solution, third-party software like TeamViewer, AnyDesk, or Chrome Remote Desktop can be extremely useful. I’ve used TeamViewer on several occasions, and it’s one of my favorites because it’s easy to set up and doesn’t require complicated network configurations. These tools allow you to connect to a remote PC with just an internet connection and can often bypass network firewalls.

3. Step-by-Step Guide for Repairing Windows 10 on Another Computer

Once you have the right tools, the next step is to actually perform the repair. The process will depend on the specific issue, but here are the general steps I follow when repairing a remote system.

3.1 Step 1: Connect to the Remote Computer

First, establish a remote connection to the target machine using one of the tools mentioned above. If you're using Remote Desktop, simply open the app, enter the IP address or computer name of the remote machine, and log in using the credentials provided. For third-party tools like TeamViewer, follow the instructions to connect using a generated ID and password.

3.2 Step 2: Run Windows Updates

Once connected, the first thing I recommend doing is running Windows Update. Many issues can be resolved by simply installing the latest system updates. In some cases, Windows Update will automatically fix bugs or replace corrupted system files. To run Windows Update, go to Settings > Update & Security > Windows Update, and then click Check for Updates. Allow any updates to install and restart the computer if needed.

3.3 Step 3: Run System File Checker

If Windows Update doesn’t solve the problem, the next tool I use is the System File Checker (SFC). This built-in tool scans and repairs corrupted system files, which can often cause Windows to malfunction. To run SFC, open Command Prompt as an administrator and type the following command: sfc /scannow. Press Enter, and the tool will start scanning for issues. If it finds any, it will automatically fix them.

3.4 Step 4: Use the DISM Tool

If SFC doesn’t resolve the issue, the Deployment Imaging Service and Management Tool (DISM) can be used. DISM is another powerful utility that can fix issues with the system image, including corruption that may prevent SFC from working properly. To use DISM, open Command Prompt as an administrator again, and enter the command: DISM /Online /Cleanup-Image /RestoreHealth. This process can take several minutes, so be patient.

4. Common Windows 10 Issues and How to Fix Them Remotely

During my remote repairs, I’ve come across several common issues that people often encounter with Windows 10. Here’s a list of these issues and how I typically resolve them:

4.1 Slow Performance

If the computer is running slow, the first thing I check is the Task Manager to see if any programs are consuming too many resources. I also run disk cleanup and disable unnecessary startup programs to improve performance. Additionally, checking for malware using Windows Defender or a third-party antivirus can help speed things up.

4.2 Blue Screen of Death (BSOD)

The infamous BSOD can occur for many reasons, including faulty drivers or corrupted system files. When this happens remotely, I typically start by checking the Event Viewer for error codes and then look up the specific code online to determine the cause. In many cases, updating the drivers or running SFC and DISM fixes the problem.

4.3 Application Crashes

Frequent crashes in apps like Microsoft Office or Chrome can be a sign of corrupted files or outdated software. To fix this remotely, I make sure that all applications are updated and reinstall any that are causing issues. If a specific app continues to crash, I check for system compatibility or try running it in compatibility mode.

5. How to Avoid Future Windows 10 Issues

Once the issue has been resolved, I recommend taking steps to prevent future problems. Regularly updating Windows and keeping all software up to date is one of the best ways to avoid future issues. Additionally, performing routine maintenance, such as running disk cleanup and scanning for malware, can keep your system running smoothly. For remote repairs, ensure that you have a reliable backup system in place in case anything goes wrong during the repair process.
