Windows is the most widely used operating system on computers, powering millions of devices globally. However, like any software, Windows can encounter issues that disrupt its normal functioning. In this article, we will discuss various methods to fix Windows on your computer and ensure it runs smoothly.

Step 1: Restart Your Computer

Sometimes, a simple restart can fix minor glitches in Windows. Press the Windows key, click on the power icon, and select “Restart.” Give your computer a few moments to complete the restart process and check if the issue persists.

Step 2: Check Hardware Connections

Verify that all hardware components, such as your monitor, keyboard, and mouse, are properly connected to your computer. Loose connections can lead to display or input issues.

Step 3: Update Drivers

Outdated or corrupted device drivers can cause numerous problems in Windows. To fix this, open the “Device Manager” by pressing the Windows key + X and selecting it from the list. Right-click on the device with an exclamation mark, select “Update driver,” and follow the instructions.

Step 4: Run Windows Update

Keeping your Windows operating system up to date is vital for its smooth functioning. Open the Start menu, type “Windows Update,” and click on the “Windows Update settings” option. Click on “Check for updates” and install any available updates.

Step 5: Scan for Malware

Malware infections can severely impact your computer’s performance. Run a reliable antivirus or antimalware program and perform a full system scan to detect and eliminate any malicious software.

Step 6: Perform a System Restore

If your computer is experiencing issues after a recent change or installation, performing a system restore can help. Press the Windows key, search for “System Restore,” and select it. Choose a restore point prior to when the problem began and follow the on-screen instructions.

Step 7: Use the System File Checker (SFC)

The System File Checker is a built-in Windows utility that scans and repairs corrupted system files. Open the Command Prompt as an administrator by typing “cmd” in the Start menu, right-clicking on “Command Prompt,” and selecting “Run as administrator.” Then type “sfc /scannow” and hit Enter. Wait for the process to complete and follow any instructions given.

Step 8: Run the Windows Memory Diagnostic Tool

If your computer frequently crashes or experiences random errors, it could be due to faulty RAM. Windows provides a memory diagnostic tool to identify and resolve memory-related issues. Press the Windows key, type “Windows Memory Diagnostic,” and select the tool. Choose to “Restart now and check for problems,” and your computer will perform the memory test during startup.

Step 9: Perform a Clean Boot

A clean boot starts Windows with a minimal set of drivers and startup programs, which allows you to identify software conflicts. Press the Windows key, type “System Configuration,” and open the tool. In the General tab, select “Selective startup” and uncheck “Load startup items.” Proceed to the Services tab, check the “Hide all Microsoft services” box, and click “Disable all.” Apply the changes and restart your computer.

Step 10: Reinstall Problematic Applications

If you are experiencing issues with a particular application, consider reinstalling it. Uninstall the program from the Control Panel, restart your computer, and install the latest version from the official website or a reputable source.

Step 11: Contact Technical Support

If none of the above steps resolve the issue or you are unsure about performing advanced troubleshooting, it is advisable to contact technical support. Their expertise can help identify the problem and guide you through the necessary steps.
