How to repair the Error 15 File not found an issue in Windows?

We will discuss two methods to repair the Error 15 file not found in Windows:

Advanced Computer User Resolution (manual):

Sign in the administrator after switching on your computer.
You then have to click on the Start button, click on "˜All Programs', "˜Accessories', "˜Tools', after which you'll have to select System Restore.
From the next window, you can select "˜Restore my PC to a prior period', and then you are supposed to click on Next.
Pick the most current "˜System Restore' data that is available within the "˜Click a restore date' list, and then click on Next.
In the verification screen, click on "˜Next'.
You then need to reboot the computer after the rescue has been completed.

Beginner Resolution (totally automatic):

This is another step if you are looking to fix the Error 15 file not found an issue with your system:

Download and open the (Error 15 File Not Found Windows 7) restoration software program.
You then have to install the application, and merely click on the Scan button in the software.
You are then required to click on the "˜Repair Errors' button in the software when the diagnostic scan has been finished.
Reboot and finish the process.

Running the SFC Command to deal with Corrupted Files:

Since corrupted files are a major reason behind the Error 15 file found code, we deal with a method to remove the corrupted files.

The process has to be carried out from the Administrator Command Prompt window. If you are using Windows 10, you can simply right-click on the Start button, select "˜Command Prompt (Admin)', and if you are using a different version of Windows, you can access it by searching the Start Menu for Command Prompt, right-click over it, and select the option of "˜Run as Administrator'.
You then have to type the following command into the Command Prompt window, and press Enter. This would help you to run a complete system scan: sfc/scannow
You can then leave the command prompt window open until the command completes its execution. This can take a while depending on the condition of the system. If no error is detected by the command, you'll see a message which would say, "Windows Resource Protection did not find any integrity violations".
However, if you see an alternate message which might read, "Windows Resource Protection found corrupt files but was unable to fix some of them", you have to carry out the reboot in safe mode before doing anything else. For the ones who are using Windows 10, accessing the Safe Mode might be tricky as the booting takes place in a very short amount of time, but it can be done by holding the Shift key while clicking the restart option which will allow them to access the advanced boot options menu. For the earlier variants of Windows, one has to hold up the F8 key while the booting takes place. You then have to run the above command in the safe mode.
