Hello, I'm an expert in troubleshooting and optimizing Windows systems. When you're experiencing performance issues with Windows 10, there are several steps you can take to improve the system's responsiveness and speed. Here's a comprehensive guide to help you troubleshoot and fix performance issues on your Windows 10 computer.

Step 1: Check for Windows Updates
Before you start troubleshooting, it's always a good idea to ensure your system is up to date with the latest patches and updates from Microsoft. These updates often include performance improvements and bug fixes.

Step 2: Scan for Malware
Malware can significantly slow down your computer. Use Windows Defender or a reputable third-party antivirus program to perform a full system scan.

Step 3: Clean Up Your Hard Drive
Over time, your hard drive can become cluttered with unnecessary files. Use the built-in Disk Cleanup tool to remove temporary files, system files, and other unnecessary data.

Step 4: Check for Background Processes
Some applications start automatically when you boot up your computer and can run in the background, consuming system resources. Open Task Manager (Ctrl + Shift + Esc) and check for any processes that are using a high percentage of your CPU or memory.

Step 5: Adjust Visual Effects
Windows 10 has several visual effects that can be resource-intensive. Adjusting these settings can free up system resources.

Step 6: Modify Virtual Memory Settings
Virtual memory is a space on your hard disk that Windows uses as if it were RAM. You can increase the paging file size to improve performance.

**Step 7: Disable Unnecessary Startup Programs**
Some programs are set to start automatically when Windows boots, which can slow down your system. Use Task Manager to disable unnecessary startup programs.

Step 8: Check Your Hardware
Sometimes, performance issues can be caused by failing hardware. Check your hard drive for errors, ensure your RAM is functioning correctly, and consider upgrading your hardware if it's outdated.

Step 9: Optimize Your Network
If you're experiencing slow internet speeds, this can also affect your computer's performance. Check your network settings and consider upgrading your internet plan or hardware.

Step 10: Consider a Clean Install
If all else fails, a clean install of Windows 10 can often resolve persistent performance issues. Be sure to back up your data before proceeding.

Now, let's dive into the specifics of adjusting the appearance and performance of Windows and modifying virtual memory settings as mentioned in your reference material.

Adjusting Appearance and Performance:
1. Open the Start Menu and find the Control Panel. Click on it.
2. In the Control Panel, go to the Search field at the top-right of the window and type "Performance". Now hit Enter.
3. Find and click on "Adjust the appearance and performance of Windows".
4. In the Performance Options window, you can choose between a visual effects scheme designed for best appearance or best performance, or you can customize your settings.

Modifying Virtual Memory Settings:
1. In the same Performance Options window, go to the Advanced tab.
2. Under the Virtual Memory section, click on "Change".
3. Uncheck "Automatically manage paging file size for all drives" if it's selected.
4. Select your main drive (usually C:) and choose "Custom size".
5. Enter an initial size and maximum size for the paging file. A common recommendation is to set the initial size to 1.5 times your RAM and the maximum size to twice or three times your RAM.

Remember to click "OK" or "Apply" to save your changes and restart your computer for the changes to take effect.
