Win8/8.1/win7 picked out the real culprit in the C-disk space.

Many use Win8, Win8.1 users are not difficult to find, originally only occupied 20G size system disk, with the increase in use time, the disk space of C disk is continuously reduced, that this part of the space where to reduce?

Due to the special environment of Windows systems, the generally reduced space is mainly concentrated in the following:

Registry: User data and program data are constantly written to the registry, so the registry becomes larger.

Patch installation: When Windows update Automatic Updates is turned on, there will be new patches released almost every month. Installing patches requires additional space (patches replace some files and back up the original files).

System Restore: System Restore automatically creates restore points and requires hard disk space.

Store cache: The store will occupy some space when it downloads an app with residual cache file deposits.

Other files, such as dormant temporary files and system-driven backups, are also larger.

Now that you know the system disk occupies the real killer, how to give a bloated system disk to lose weight?

1, the first analysis of their own system disk large file directory and number, you can use the Disk Space Analysis tool or system slimming tool analysis, what big files or programs.

From the above can see the system disk mainly by a number of display/semi-hidden system folders, plus a few system single files: 32-bit or 64-bit software installation directory program files, recording application registration written to the profile directory Programdata, The Windows system home directory, user personal data users, and other restore point files directory recovery and the system SYS file produced by sleep hibernation.

2. After analyzing the disk condition of the system disk, we know the situation of large file or file occupancy, and then start the thin body operation of the system disk. For example, the system Slimming tool, safely remove the system files can be cleaned.

3, Program files or programs files (x86) Slimming: Used to store the application of the installation files directory, occupy a certain volume, you can unload some large-sized procedures.

4, Programdata thin body: Not recommended, store most of the application software and program configuration information

5. Windows System Home directory: A variety of temporary files that are stored for each month of the system Windows Update upgrade backup, including temporary caches that are generated after the store app is downloaded. Support for manual removal or removal of third-party tools.

The exact path is the following: C:windowssoftwaredistributiondownload

6, User personal data users: stored in the software temporary files or the user's daily operation of the production of various temporary files, volume is not very large, but the time is long, can also make up. Because temporary files belong to system-hidden files, they can be resolved using a third-party security Cleanup tool.

7. Other restore point Files directory recovery: Store manually created or system automatically generated restore points, recommended to adjust the upper limit, not recommended to turn off this feature.

Here's how: right-click My Computer, select Properties, and go to the System Information summary page.

Then select the System Protection feature, the system is turned off by default, it is recommended to manually turn on (enable) and configure the amount of disk space usage.

8. System SYS file generated by sleep hibernation

As the windows8/8.1 introduces a fast start function, which speeds up the boot speed, if the Hibernate function is turned on, the system disk will generate a large system hibernation file, such as physical memory, Pagefile.sys and Hlberfil.sys files.

You can use powercfg/h on or powercfg/h off administrator: Command prompt to turn on or off hibernation.

The above scheme is also applicable to Win7 platform
