Let's talk about “Error 15: file not found” on Windows 10

You are working on your computer and suddenly on the monitor screen you see the message "Error 15: file not found". All open programs are closed, and when you try to reopen them, the message "Error 15: file not found" appears again. In addition, the system, computer mouse and keyboard freeze up. This error can also be seen when installing the OS or any program. It is also not surprising if you encounter error 15 during system startup or shutdown.

If you get such an error on your monitor, you need to fix error 15 as soon as possible. Otherwise, you might have big trouble, such as data loss.

Why do I see error 15 on my computer?

Most often, "Error 15: file not found" appears due to incorrect or incomplete installation of the OS. There are a few other reasons for which users should pay attention:

Problems with the registry

Damage of some important system files by virus or malware

The system is out of date due to the lack of timely updates

The hard disk is overloaded with information because of what can not work correctly

Now the problems are clear. But, how do you fix error 15?

Don't panic: there are several suitable methods for this.

Method 1. Use the antivirus

So, the first thing you have to do is scan the entire system with an antivirus application. If the antivirus is good and has the latest updates, then most likely it will find viruses and malware on your computer. After the computer is cleared of them, reboot it and check whether "Error 15 file not found" appears. If everything is good, congratulations! The problem is solved. If this way failed, do not worry; proceed to method 2.

Method 2. Run SFC wisely

Many users claim that this method is good if used in safe mode. Here is a quick tutorial on how to do it:

Power up the computer and then constantly press the Shift and F8 keys. Once you see Advanced Boot Options, select "safe mode". Confirm the action by pressing Enter. You are now in safe mode and can use SFC.

First, right-click on Start and select "Command Prompt (administrator)". At the command prompt, type:

sfc /scannow

Now press the Enter key.

This will start scanning the system for errors and then correct them. It is necessary to wait until the end and restart the computer. Now check if "Error 15: file not found" hinders you or not.
