Windows 10 100 Percent Disk Usage Problem

We've recommended that you consult the device manufacturer for isolation purposes as a damaged hard drive may also cause the issue. Since the issue persists after resetting your PC, we'd like to look at the hardware aspect of the matter. Should you wish to continue, we'd recommend an performing an  in-place upgrade. An in-place upgrade is the installation of Windows 10 over an existing Windows 10, keeping your files, applications, and settings while updating your PC. By performing an in-place upgrade, you will clean up the system which may help resolve some troubles with the system.

For any results, kindly update this thread.

My issue not resolved. 

If this is device related,  we would not have seen these many posts about the same issue. Just google disk 100 % full and see how many pages it give and how many people are struggling on the same bug.

For me this is Windows 10 issue.

If you can't help let it be like this and people know that it is an unsolvable crazy bug and they wont waste time in asking this again in this forum.

Hi,

We're following your post and we noticed that it has been idle for more than 48 hrs. We'd like to know if the issue still persist and an assistance is still needed. If the issue persists, we'd recommend consulting the device manufacturer about the issue so they can run diagnostics and to get further assistance as we suspect that this is a possible hardware failure.

We look forward to your response.

Hi , Thanks for the reply. 

I am noticing this lagging issue since day1 of the laptop bought. I tried couple of times resetting the PC from the options (option1 with remove everything as sub option ) suggested before posting on forum. when it reset, first thing i do is open task manager and observe disk and it always  reached 100 %  as soon as it was on for the first time . For a change i tried loading previous version of OS today and opened task manager immediately when it turned on after reset, Screen shot is below :( :( 

Windows 10 has a feature that allows end-users to reset the operating system in the event that they want to start over 100% back to factory defaults or, just reinstall the operating system yet keep all your files. The feature is called Reset this PC and it’s extremely handy if you’re experiencing stability or performance issue. Resetting your device won’t uninstall your current build. This is because of resetting, as a function, aims to reinstall the default state of your PC’s current version. 

To assist you with your concern, we recommend that you try to reset your PC using the Windows environment option or the WINRE (Windows Recovery Environment) mode. To do this, follow the steps below:

2. Click on Update & Security.
3. In the left pane, select Recovery.
4. Now in the right pane, under Reset this PC, click on Get Started.
5. Follow the on-screen instructions carefully.

If the “Reset” function doesn’t work in the operating system. You can try the WINRE (Windows Recovery Environment) mode. To do this, follow the steps below:

1. Click “Recovery” then select “Advanced startup”.
2. Click “Restart now”, the operating system will reboot into WINRE (Windows Recovery Environment) mode.
