Users trying to upgrade my Windows 7 to Service Pack 1 will still receive error 800F0A13. What could be the reason for this? Why are they getting this error code now?
Here are some instructions you need to follow to solve this problem.
Performing a Start-up Repair
The boot repair tool repairs Windows 7 by replacing important files in the operating system that may be corrupted or missing. Startup Repair is a simple diagnostic and repair tool that you can use if Windows 7 does not start properly and you cannot use the safe mode.
- Booting from the Windows 7 DVD
- Wait until Windows 7 has loaded the files.
- Select the Windows 7 configuration language and other settings.
- Click on Repair Computer.
- Wait until the system recovery options find Windows 7 on your computer.
- Select your Windows 7 installation
- Select the Start-up Repair Tool.
- When starting the repair, wait for problems with Windows 7 files.
- During the boot process, wait for repair attempts to repair Windows 7 files.
- Click Finish to restart Windows 7.
Launch the System File Checker (SFC.exe).
- To do this, click Start, type Command Prompt or cmd in the search box, right-click Command Prompt, and then click Run as Administrator. If you are prompted to enter an administrator password or confirmation, type the password or click Allow.
- If you are using Windows 10, Windows 8.1 or Windows 8, first run the DISM (Inbox Deployment Image Servicing and Management) tool before launching System File Checker. (If you are using Windows 7 or Windows Vista, proceed to step 3.)
- Type the following command, then press Enter. It may take several minutes for the command operation to end.
DISM.exe /Online /Cleanup – Image /Health restoration
Important : When you execute this command, DISM uses Windows Update to provide the necessary files to troubleshoot errors. However, if your Windows Update client is already down, use a running Windows installation as a repair source or a Windows folder side by side from a network share or removable disk, such as the Windows DVD, as the source for the files. To do this, execute the following command instead:
DISM.exe /Online /Cleanup Image /RestoreHealth /Source:C:\RepairSource\Windows /LimitAccess
Note: Replace the C:\RepairSource\Windows wildcard character with the location of your repair source. Learn more about using the DISM tool to repair Windows.
At the command prompt, type the following command, then press ENTER:
The sfc /scannow command scans all protected system files and replaces corrupted files with a cached copy located in a folder compressed to %WinDir%\System32\dllcache.
The %WinDir% fill character represents the Windows operating system folder. For example, C:\Windows.
Run the System Update Readiness Tool
The System Readiness Update Tool or CheckSUR fixes this problem. These updates include the CheckSUR (Check for System Update Readiness) tool. The CheckSUR tool searches for inconsistencies on your computer and corrects them during installation. Please note that on some computers, the analysis can take up to 15 minutes or more. Even if the progress bar seems to stop, the analysis continues, so do not cancel the process.
