Why does win10 disk occupy 100

If the disk usage of your win10 system remains high, consider whether it is poisoned, etc., try to boot up and press f8 to safe mode, and then take a look at the full antivirus.

The first option: family group.

Homegroups are one of the reasons why your hard drive is hogged. Some users have reported that after turning off HomeGroup, the hard disk occupancy has dropped from 90% to about 10%, but for users who are not part of HomeGroup, this method may not solve the problem.

Enter "HomeGoUp Listener" and "HomeGroup Provider" in the Windows search, right-click to enter "Properties", and set the startup type to "Disabled" after the operation is stopped.

Win8 enables virtual memory by default, and it will dump the memory of some applications to the hard disk to avoid the situation of insufficient physical memory. If the user's physical memory is above 4GB or even 8GB, you can try to reduce the virtual memory, but it is best not to lower it is 2048MB.

Right-click on "This PC", click on "Properties", click on "Advanced System Settings", "Settings", "Advanced", and then click "Change" in the virtual memory column to allocate virtual memory as needed.

The third option: IPv6

Under win8, the IPv6 function is turned on by default, and it has some responsibility for the high disk occupancy. Therefore, it is recommended that users who do not use IPv6 turn it off.

Open the Network and Sharing Center, click "Change Adapter Configuration" in the upper left corner, select the NIC you are using, right-click, then click "Properties", slide down and find the IPv6 option to turn it off.

Fourth scenario: Windows Defender

Windows Defender scans your hard drive on a regular basis, and in previous versions, this feature could be turned off. If it is not turned off, the hard disk usage may remain high and the system as a whole will freeze. Users can try to restrict Defender's scheduled scans with Group Policy or turn off Defender to resolve the issue.

Enter in the search bar to open Group Policyr, navigate to "Specify a different day of the week to run scheduled scans" in "Computer Configuration - Administrative Templates - Windows Composition - Windows Defender - Scanning" configured as "Enabled" and select the setting according to the content in the help. Or turn it off directly in the Windows Defender settings in the in-management options.

The fifth option: Windows Search

For older PCs, Windows Search uses a lot of system resources and can be turned off. However, the negative effect is that you will not be able to use intelligent search, and you will lose a good integration experience in Win8 or Win10.

Method 1: Open Task Manager and click the Disk Usage column to sort and view the apps that occupy the highest disk usage. If the highest usage is always the same third-party program, you can try uninstalling it.

Note: The disk usage will be very high due to frequent reading and writing of the disk during boot, and the disk usage will gradually decrease after the boot is complete.

Method 2: Press the win key + R key at the same time, enter regedit, and click OK.

Find the hkey loacal machine in the registry and take it.

Then find software-microslft-dfrg, bootoptinizefunction, and optimizecomplete, double-click on it.

<> in the dialog box that pops up, set the value of optimizecomplete to"no"

Then close the registry and restart it to check the disk usage.

Method 3: If there is a lag or increase in disk usage after the system version upgrade, and if so, and the methods such as closing the homegroup and modifying the registry are invalid, you can revert to the previous version. If you are experiencing stuttering after installing some Windows updates, you can try deleting the most recently installed Windows updates.

Method 4: If the system has not been upgraded, you can check the system update in the settings and try to update the system.

Method 5: If the conditions of the machine allow, it is recommended to replace or install an SSD.
