100% Disk Usage on Windows 10 - But installation pendrive reduces it from 100 to 50%

[AkshayGaurSX]

I did a reinstallation of windows 10 in my laptop but it created a issue of 100% disk usage and this issue is not becuase of any service or update or driver. But Actually this isuue has some relation with the USB installation pendrive Because when i inserted that pendrive, immediaetly the disk usages reduced to 50% from 100%. And when i eject that pendrive, immediaetly it increses from 50 to 100%.

I have reistalled the window 4 times and each time same issue occurs. I changed the pendrive but same issue occurs. And that Installation usb is made by official microsoft software, which directly download the window from microsoft.
