– After the update is installed, check for any new updates and continue the process until there are no more pending updates.
In conclusion, installing pending updates is crucial for the smooth functioning and security of your device. Therefore, make it a habit to regularly check for updates and install them as soon as they become available. This will not only improve your device’s performance but also protect your data from potential cyber threats.
4. Check for Malware
Malware, also known as malicious software, is a type of harmful program designed to disrupt, damage, or gain unauthorized access to a computer or network. It can cause various issues such as slowing down your computer, stealing personal information, or displaying annoying pop-ups and ads. As a tech blogger, it is important to know how to check for malware on your devices and how to protect yourself from it.
Here are 4 steps to check for malware on your computer:
1. Update your anti-virus software
The first step to protecting your computer from malware is having a reliable anti-virus software installed and regularly updating it. Anti-virus software scans your system for known malware and prevents any malicious programs from infecting your device.
2. Perform a full system scan
Once your anti-virus software is up to date, perform a full system scan to search for any potential threats. This may take some time depending on the size of your hard drive and the number of files on your computer. Make sure to let the scan run its course without interrupting it.
3. Use online malware scanners
In addition to your local anti-virus software, you can also use online malware scanners to do a thorough check of your system. There are many reputable websites that offer free online malware scanning services. Some popular options include VirusTotal, ESET Online Scanner, and Kaspersky Virus Removal Tool.
4. Manually check for suspicious files
If the above steps did not detect any malware, you can still manually check for any suspicious files. Look through your computer’s system folders and scan any newly downloaded or unfamiliar files with your anti-virus software before opening them.
It is also important to take preventive measures to avoid malware in the future. These include being cautious when clicking on links or downloading attachments from unknown sources, keeping your operating system and software up to date, and using a virtual private network (VPN) when connecting to public networks.
In conclusion, as a tech blogger, it is crucial to regularly check for malware on your devices to ensure your personal information and data are safe. By following these steps, you can minimize the risk of malware infecting your computer and protect yourself from potential cyber threats.
5. Deploy SFC and DISM scans
System File Checker (SFC) and Deployment Image Servicing and Management (DISM) are two powerful tools used for diagnosing and repairing issues with the Windows operating system. In this blog post, we will discuss how to deploy SFC and DISM scans on your computer.
1. What is SFC?
SFC is a command-line tool that scans all protected system files and replaces any corrupted or missing files with the correct versions from the Windows installation media. This helps to ensure that the system files are not damaged or missing, which can lead to various issues like crashes, errors, and software malfunctions.

Step 2: In the Command Prompt, type “sfc /scannow” and press Enter.
Step 3: The scan will begin and may take some time to complete. Once it’s done, you will see a message stating whether any corrupted files were found and if they were successfully repaired.
Note: If SFC is unable to fix the issues, you can use a Windows installation media to manually replace the corrupted files.
3. What is DISM?
DISM is a command-line tool that is used to service and repair Windows images. It can be used to fix issues with corrupt system files, Windows updates, and even to repair the Windows operating system itself. It is particularly useful when an SFC scan is unable to fix system file issues.
4. How to deploy DISM scan?
To run a DISM scan:
Step 1: Open the Command Prompt as an administrator.
Step 2: In the Command Prompt, type “DISM /Online /Cleanup-Image /RestoreHealth” and press Enter.
Step 3: The scan will begin and may take some time to complete. Once it’s done, you will see a message stating whether any issues were found and if they were successfully repaired.
Note: If DISM is unable to fix the issues, you can use a Windows installation media to repair the system image.
5. When should you deploy SFC and DISM scans?
It is recommended to run SFC and DISM scans when you experience issues with your Windows operating system, such as errors, crashes, or application malfunctions. You can also run these scans as a regular maintenance task to ensure your system files are intact and functioning correctly.
In conclusion, SFC and DISM scans are powerful tools that can help diagnose and repair issues with your Windows operating system. By deploying these scans, you can ensure that your system files are in good condition and your computer is running smoothly.
6. Perform a System Restore
System Restore is a helpful feature in Windows that allows you to revert your computer’s settings and system files to a previous state. This can be useful if you’re experiencing errors or issues with your computer, as it can often fix them by resetting problematic settings.

Step 3: Confirm the Restore Point
A new window will open, asking you to confirm the restore point you’ve chosen. It’s essential to double-check that you’ve selected the correct restore point, as this cannot be undone once it’s performed. If you’re confident, click on “Next.”
Step 4: Begin the Restore Process
Before the system restore starts, you’ll be given a summary of the changes that will occur. If you’re satisfied with the information, click “Finish” to begin the process.
Step 5: Wait for the Restore to Complete
The system restore process may take some time to complete, so be patient. Your computer will restart during this process, and you may see a “System Restore in Progress” screen. Do not interrupt this process, as it may cause problems with your system.
Step 6: System Restore Complete
Once the system restore is complete, your computer will restart, and you’ll see a message stating that the process was successful. You can now log in and check if the issue you were experiencing has been resolved.
In conclusion, System Restore is an effective way to fix issues on your Windows computer by restoring it to a previous state. If you’re facing any problems with your system, try performing a system restore and see if it helps. It’s always a good idea to create restore points regularly to have multiple options available should you need to use this feature. Keep your computer running smoothly and efficiently with the help of System Restore.
7. Perform a Clean install
A clean install, also known as a fresh install, is the process of wiping all the data on a computer and then reinstalling the operating system. It essentially gives you a clean slate and can help improve the performance and stability of your computer.
Performing a clean install can be a time-consuming process and requires advanced technical knowledge. However, it can be worth it in the long run if your computer is experiencing frequent crashes or becoming slow due to cluttered system files and configurations. Here’s how to perform a clean install on your computer:
1. Backup your important data: Before proceeding with a clean install, make sure to back up all your important files and documents. This process will erase everything on your computer, so it’s crucial to have a backup to restore your data later.
