Scanning Windows 11 for issues is a breeze. All you need to do is use the built-in tools to ensure your system is running smoothly. Hereโs a quick overview: Open the Windows Security app, run a full scan to check for viruses and malware, and use the System File Checker (SFC) tool to fix any corrupted files. Thatโs it! Follow these detailed steps to do it right.
Step-by-Step Tutorial on How to Scan Windows 11
This guide will help you thoroughly scan your Windows 11 system to detect and fix any issues, ensuring its performance remains top-notch.
Step 1: Open Windows Security
Go to Start, type โWindows Security,โ and press Enter.
Windows Security is your go-to app for keeping your system safe. Itโs built right into Windows 11, so you donโt need to download anything extra. Just open it up, and youโre on your way to a healthier PC.
Step 2: Run a Quick Scan
Click on โVirus & threat protection,โ then click โQuick scan.โ
A Quick Scan is a fast way to check the most common places where malware hides. This wonโt take long, usually just a few minutes, and itโs a great first step to spot any obvious issues.
Step 3: Run a Full Scan
If the Quick Scan doesnโt find anything, click โScan optionsโ and select โFull scan,โ then click โScan now.โ
A Full Scan covers every nook and cranny of your system. Itโs more thorough but will take more time. Youโll want to do this when you donโt need to use your computer for a while.
Step 4: Use the SFC Tool
Open Command Prompt as an administrator by typing โcmdโ in the Start menu, right-clicking it, and selecting โRun as administrator.โ Then, type sfc /scannow and press Enter.
The System File Checker (SFC) tool will scan for and repair corrupted system files. Itโs like a health check-up for your OS. This might take some time, but itโs worth it to ensure everything is in tip-top shape.
Step 5: Check the Results
Once the scans are done, review the results and take any recommended actions.
After everything finishes, youโll see a report. If any threats or issues were found, Windows Security will provide steps to resolve them. Follow these prompts to keep your system safe.
Once you complete these steps, your Windows 11 system will be scanned for any threats or issues, and youโll have taken steps to fix them. This should help keep your computer running smoothly and efficiently.
