What should I do if win10 occupies a high hard disk

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.

Because after the homegroup is enabled, the system will constantly use the hard disk to copy file shares, resulting in the hard disk occupancy reaching more than 90%, which affects the system speed. Most home computers don't need to share files to a local area network.

Here's how to fix it:

1. Open Control Panel - Management Tools - Services.

2. Find the "HomeGroupListener" service, double-click to open or right-click the "Properties" command.

3. In the pop-up properties window, click the drop-down box of the startup type in the General tab, and select "Disable" from the list that appears. Then click the "Stop" button in the service state, and click the "OK" button to save the settings after modification.

Installing an SSD will solve the problem once and for all.

Try Windows Defender to exclude explorer folders and processes.

You need an SSD, and a mechanical drive does.

Change the system,Win10 is not as good as Win7 at this stage。
