Preparing for Repair

Before fixing your Windows 10 computer, it’s important to get ready. This means understanding your options, making backups, and knowing how to access tools for repair.

Understanding System Recovery Options

Windows 10 offers several ways to repair your system. These include tools like System Restore, Safe Mode, and the Recovery Environment.

Creating Backup and Recovery Media

Always back up before repairs. Use the Backup settings to save your personal files. Then use the Media Creation Tool to make a recovery drive.

Accessing Advanced Startup Options

To access repair tools, you may need to start Windows in a special way. You can do this through the settings under Update & Security or by holding the Shift key while you click Restart.

Evaluating System Health

Check the health of your system first. The System File Checker tool (sfc /scannow) and the DISM tool can find and fix corrupted system files.

Fixing Startup Issues

If Windows won’t start, you can fix it with tools in the Advanced Startup options. These tools can help fix problems that stop Windows from loading.

Updating Windows 10

Sometimes, simply updating Windows can fix problems. Check for updates in Settings and install any that are available.

Repairing with Command Line Tools

Command Prompt and PowerShell are powerful tools. Use commands like sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth to repair system files.

In-Place Upgrade Repair Install

If other repairs don’t work, you can reinstall Windows 10 and keep your files. Use the Windows 10 installation media and choose to upgrade your PC.

Performing the Repair

When Windows 10 has issues, a repair can often fix them. This section covers reliable ways to perform a repair without losing data.

Running System File Checker

The System File Checker is a tool that checks for damaged Windows system files. If it finds and can repair them, it will. To use it, open a command prompt as an administrator and type sfc /scannow.

Steps to run SFC:

  1. Open “Command Prompt” with admin rights.
  2. Type sfc /scannow and press Enter.
  3. Wait until the scan completes.

The scan results are in the CBS.log file. This file shows files that SFC could not fix.

Utilizing Deployment Image Servicing and Management

The Deployment Image Servicing and Management tool, or DISM, fixes Windows system images. It helps prepare the system for SFC to work better.

Running DISM:

  1. Open Command Prompt as an administrator.
  2. Type DISM /Online /Cleanup-Image /RestoreHealth and hit Enter.
  3. Let the scan run and complete.

DISM can fix problems SFC can’t. Always use DISM before SFC.

Executing a System Restore

System Restore brings your computer back to a past state when it worked well. It uses “restore points” which are snapshots of system files and settings.

To do a System Restore:

  1. Open the Start menu and type “Create a restore point”.
  2. Click on “System Restore” button.
  3. Follow the on-screen instructions to choose a restore point and start the process.

System files change back, but personal files do not.

Resetting Windows 10

To reset Windows means to reinstall it while keeping your files or removing everything.

Reset process:

  1. Go to Settings > Update & Security > Recovery.
  2. Under “Reset this PC”, click “Get started”.
  3. Choose “Keep my files” or “Remove everything”.

Keep files to save personal data or remove everything for a clean start.

Manual Repair Methods

For manual repairs, you may need to use commands like takeown or icacls. These repair Windows system files by hand.

Sample commands to fix system files manually:

  • takeown /f filepath
  • icacls filepath /grant administrators:F

These commands change file permissions and ownership. They are advanced and should be used carefully.

Reinstalling Windows 10

Reinstalling is a last resort. Use it only when other repairs fail. You will need installation media like a USB stick or DVD.

To reinstall Windows 10:

  1. Create or find your installation media.
  2. Boot from the media.
  3. Follow the setup instructions.

Choose the same language, edition, and architecture as the current system. If you have a Windows 10 license, the setup may not ask for a key.
