Does one have to be a whiz to fix Windows?

All computer users fall into three groups:

  • beginners;
  • advanced users;
  • professionals (we also call them gods of computers).

Beginners usually go straight to the service station every time they face difficulties. Most of them are afraid to repair Windows 10 and ask for a third-party service for help. Some of them are more proficient and become something in between novice and advanced users. We often call them “fearless” ones. They are still unsure of their skills, but with some help, they act like tech-savvy users.

Advanced users know a bit more than how to use hotkeys and can fix some points using professional guides (you’ll find most of these tutorials on Microsoft support pages or our website). Professionals are computer technicians or system administrators, like Howly experts who prepared this article for you.

How to repair Windows 10

Thus, to repair Windows, you need some experience reading guides and working with menus and catalog directories – not more. If a PC misbehaves because of hardware damage, it’s better to contact the computer service.

In addition, you’ll need professional help in case your OS has non-standard features or a problem is multi-dimensional. For instance, you face an update failure, a device operates slowly during a particular session, and you hear how the motherboard beeps – and all this happens simultaneously.

In this case, you are facing an uncommon problem and it would be hard to find a Windows 10 repair solution that works for you. Hence, we encourage you to save your time and ask for professional help.

How to fix Windows 10: restore, reset, or reinstall?

Let’s use a metaphor for a clear understanding of the issue. Your OS is a house. When you feel uncomfortable in it, it’s you who decides which option is the best: to change the front door for more safety, change a couple of furniture items for refreshing, or reconstruct the interior entirely. The first alternative is easy to implement, and it’ll work as soon as you finish your job. On the other hand, the “global” approach requires much time, and, what’s more, it implies ditching all the pieces you’re accustomed to and organizing your routine in a brand new way. It could be refreshing.

Choosing between a small retooling and a massive upgrade to run a repair on Windows 10, in most cases, it’s more reasonable to opt for the first (if it’s possible). Fixing the OS that ceases or proceeds slowly by making minor changes is more productive than reinstalling because you save all the files and functions. While searching for the solution on how to run Windows repair, depending on the problem’s scale, you can:

  • Restore an OS. Simply go back to the point where your system works just fine. Maybe your hardware isn’t suitable for the latest software. And it results in glitches. You can solve it by restoring to the latest safe backup.
  • Refresh OS. Allows you to complete a system repair in Windows 10 while maintaining personal data safe.
  • Reset a PC. It’s the entire reinstallation. You’re going to lose all personal information.

You’ll never know when your PC will be out of order, so it’s a good idea to do backups of your system regularly. Another good idea is to have a recovery drive with Windows files recorded on a USB drive or DVD. Some day you may need it to do the Windows installation.

All in all, Repairing Windows 10 via System Restore is a wonderful way to make a computer function well again.

Two tools are working in collaboration to organize system files:

  • System File Checker (SFC) detects the damages in groups of files that provide booting and correct OS operating and, in some cases, replaces the cracked files.
  • Deployment Image Servicing and Management Tool (DISM) fixes the “gaps.”

There are two main commands able to repair Windows installation:

Enter them in the Command Prompt. The task is rather complicated and requires special skills and an understanding of the OS operation and data organization, in general, interpreting the system’s reports as they are.

Try a recent backup image to repair Windows 10

System File Checker is a powerful tool, but unfortunately, it can’t fix all issues. However, you can restore your system to the point where you don’t have that critical problem. By default, Windows enables this feature, so you just need to visit the menu and repair Windows 10:

  1. Write the System Restore on the search bar in Windows.
  2. Look for a Create a restore point. It opens the System Properties window.
  3. Pick Open System Restore and follow the on-screen guidelines to find the correct backup.
  4. Click Restore Now and wait until the system restores itself.

Usually, all personal files stay in place after Windows 10 system repair. Windows removes updates, freshly installed apps, and application updates. Some users manually disable this feature or ask the technician to do this to get rid of annoying messages like “You should back up your system today”. Here is instruction on how to create a backup, so you can repair Windows 10 by following this path:

  1. Type System Restore on the search bar near Windows.
  2. Pick Create a restore point → Create.
  3. Write the description that helps you identify this point.
  4. Click Create and wait for 10-30 minutes until the system creates a backup.

Once the process is done, you’ll see the system note, approving that your Windows repair tool on Windows 10 made the new restoration point. You can also set up the backup frequency, so you will always have a point to restore.
