Windows 7 Computer C disk available space getting smaller and smaller Solution

The reason why C disk space is getting smaller and smaller is that you haven't cleaned up the C disk for a long time or you have installed too many programs on the C disk, this is a problem. As long as the theorem is used to clear the C disk space and a reasonable installation program, this will not happen again.

Why is the available space of Windows 7 C increasingly small?
Generally, Windows 7 occupies about 20 GB of hard disk space. During use, it is also normal that the disk space of the system disk is gradually reduced.

 

Hide this image. How can I use the available space of drive C of this image?
These spaces are used here:

Registry: user data and program data are constantly written into the registry, so the registry will become larger.
Patch installation: when Windows Update is automatically enabled, a new patch is released every month. Installing patches requires additional space. (Replace some files with patches to back up the original files .)
System Restoration: The Restore point is automatically created and requires hard disk space.

In some cases, some disk space is also used.

You can try these methods:
1. Regular disk cleanup

We can use the system retained tool to clear some general disks. Improve performance by fragment the hard disk, and delete junk files by using disk cleanup.

2. Set the space usage limit for system restoration.

1. If the system restore function is enabled, the system automatically generates some image files, occupying the capacity of disk C. We can set an upper limit for this part of space based on the disk capacity.This step requires administrator privileges..

1. Disable sleep and sleep
   
   In addition, if the sleep function is enabled, a hidden system file is generated under the root directory of the system disk.Hiberfil. sys. It occupies a certain amount of system space, generally about the same size as the computer memory. Therefore, if the system disk space is not large enough, this large file will become a burden. If the system disk is about to be full, disable this function.
