Is Your Windows 10 File System Corrupted?


As an engineer providing support to home users and small businesses in the South Lincs area, I have seen a very high number of systems with Windows 10 file system corruption. This even stretches to a few systems that were straight out of the box, brand new!

In many cases users may be blissfully unaware that they have a fundamental problem. Often systems will continue to run but response will be sluggish or resulting issues intermittent. A common symptom is an intermittent issue with the software that controls Internet access, resulting in the occasional loss of Internet connection or dropping off the wireless network.

Even if you are not experiencing these issues I would still recommend that you test your Windows filesystem integrity by using the method detailed below.

How do I test my Windows 10?

· Right click (ie; click the right mouse button) on the Start button at the bottom left of the screen.

· In the options that pop up click on Command Prompt (Admin). Note that it must be the one that states Admin not the one without.

A black window will now open up that looks like an old basic IBM DOS system (for those that remember those).

· Type the following into this box
sfc /scannow
then press Enter on the keyboard


The system will now carry out a scan of the main Windows 10 file system, the very structure of the program code.

It may take an hour or so to complete so just leave it running. You can use your PC during this time but it will run faster if you just let in finish.

Once the tests have completed you will see one of three responses:


This is the one you want to see. Windows 10 has checked its own filesystem and found no problems. Of course if you are having intermittent issues with your system this may be bad news as it means that you have something else going on.



This is good in many ways. It confirms that there was corruption but that Windows has been able to identify and repair the damage. If you have been having issues this may well have addressed them.



You don’t want this result! If you see this one you are almost certainly going to need to do a Windows 10 refresh (a fresh install of Windows 10) to correct the problem. If you are not familiar with how to do this search online, find a friend/relative who is or contact someone like myself at LITES PC for assistance.


Hope this helps
