The available space of disk C in Win8. 1 system is getting smaller and smaller. What can we do? As we all know, the impact of drive C directly affects the running speed of the system. If the space of drive C is large enough, it will run faster. On the contrary, if the space of drive C is small, the running speed will become slower. At this time, it is necessary to slim down the C drive of Win8. 1 system so that the C drive has enough memory space. Let's take a look at the detailed setting method.

The specific method is as follows:

1, disk cleaning: enter the computer resource manager-right click-drive C-properties-disk cleaning-cleaning system files, check the space occupied by each resource and check clean, paying special attention to the previous Windows installation, that is, the Windows folder. If the system disk is not formatted when installing the system, the previous system files will be put into the Windows folder, which has a large capacity;

2. Virtual memory: Virtual memory will allocate a part of hard disk space as virtual memory, which exists in the form of page files, generally occupying 2G-4G. If your computer's physical memory reaches 4G or more, you can consider canceling the setting of virtual memory.

Right-click the computer icon-Properties-Advanced System Settings-Performance-Settings-Advanced-Change-Remove Automatic Management Check-Select Managed System-No Paging File-Settings-Apply-OK-Restart the computer;

3.WindowsUpdate Automatic Update: Delete the automatic update patch downloaded under C: \ Windows \ Software Distribution \ Download;

4. System protection: right-click the computer icon-Properties-System Protection-Configuration-Disable to delete the generated system protection file;

5. Hibernation file: use the shortcut key Win+X- command prompt (administrator) to enter: powercfg-hoff and press enter to close and delete the hibernation file;

6. Expanding partition: The most fundamental solution is to expand the capacity of partition C. At present, most mechanical hard disks run faster than the outer ring, and the system partition is the outermost ring, so the software installed on disk C is the fastest to start and read. Bian Xiao suggested using partition software such as partition assistant to adjust the capacity of disk C to 70- 150G.

7.20G Lost: If drive C loses 20G or dozens of GB for no reason, the size of the inspection folder can't match. Perhaps the value of the system protection door is too large to be occupied.

Right-click the computer icon on the desktop-Properties-System Protection-Configuration. You can see that the current system protection usage is 25.26G, and the upper limit is 75.63G, so every time you install/uninstall the software, it will be automatically backed up, and a restore point will be created to occupy it.

Click Delete to lower the upper limit door to less than 10G.

The above tutorial content is about the solution that the available space of disk C in Win8. 1 system is getting smaller and smaller. After setting, it is found that the space of disk C has become larger and the running speed has become much faster.
