You may have searched other solutions on 100% disk usage problem on Windows 10 update, like the Fix Your StorAHCI.sys Driver, Change Energy Options from Balanced to High Performance, Change Settings in Google Chrome and Skype, Disable Windows Search, Disable SuperFetch Service, Disable Antivirus Software, Uninstall Any Flash Player Update, Perform a disk check, Reset Virtual Memory, Update your device drivers or even clean install Windows 10

To be honest, I didn’t try all of those solutions except checking the volumes on the disk, I used our own utility Partition Expert to check the partition on the hard drive, you can follow the steps below or just skip this section if the command we mentioned at the begging works for you

Run Partition Expert and click on the partition ( C Drive, e.g.) to proceed when the disk map is loaded in the main interface, click on Check Volume and check both options (Fix found errors and Try to fix found bad sectors), then after seconds Partition Expert will list the log and tell the result in the window, if it says:


Windows has scanned the file system and found no problems.
No further action is required.
              

You’re free to close the window and exit this program, but if you’re about to try more solutions that you just googled, we strongly recommend you backup the disk or partition before actually editing the Registry, fortunately, Partition Expert has already built-in the copy function for us to backup data

The following steps are for backup data from one partition to another, you can use this function before you perform some operations to the volumes contain import data

1. Download Partition Expert, install, and run it, or if you don’t want to install it to Windows, feel free to use the portable edition, which has exactly the same functions as the installation one

2. In the main interface, click on the partition you’d like to backup, and plug a blank disk (USB, or an external hard drive), or just create one unallocated space on the same disk if there are no external empty media, then click Copy Volume

copy_volume

3. Click on the target unallocated space and click Next to proceed, then click Finish if the default setting suit you or just manually adjust the target space and drive letter for the new partition (copied volume will create a new partition so you can access the data), and finally commit the operation in the main window

Here’s the complete guide on how to copy volume
