    Windows 8.1 Heavy Hard Disk Activity


    Hello,

    I have installed a fresh copy of Windows 8.1 Professional recently (about a month ago). It's running fine mostly but there is one thing that keeps irritating me, whenever I leave my PC idle for long (like half hour or so), the system start to do something in background with hard drive light constantly lit.

    This keeps going on until I come back and start doing something or it randomly stops doing it. This also happens during work too but rarely. I have heard that file indexing and windows update are possible culprits behind this issue and turned them off but it is still happening. I don't know what's wrong with this OS, it never happened with Windows 7 before.

    I mostly use my system for gaming (Steam) and have no antivirus installed beside Windows Defender, in addition to that there is no 3rd party de-fragment program installed. When this happens during games it makes game performance sluggish which is the major cause of annoyance for me. Please advice me ?

    Thanks.

    You can turn it off by selecting the drive. Select *Manage, Optimize.
    Turn off the optimization.

    *Manage will not become visible until the drive is selected.
