Win7 to solve the C disk occupies a large space method

Install a pure version of the Win7, give it 15G, also did not install a few software, incredibly surplus space less than 1G.

The following describes how to solve the problem of large space Win7 occupancy.

There are three steps: (Of course, make sure you don't put too much useless stuff in the C disk)

1. Reduce the volume of dormant files

Run the command prompt with an administrator, enter: Powercfg–h size 50

The hibernation file will be compressed to 50% of memory, reducing the amount of hard disk space occupied by 25% of the memory.

If it's not enough, use powercfg–h off to close it directly.

2, set the virtual memory paging file size

To run systempropertiesadvanced, open advanced System Properties:

Custom size Virtual Memory

3, Compressed System installation folder (C:windowswinsxs folder)

First get permission to do this: how Windows 7 gets administrator privileges

How to: First get the WinSxS folder read and Write permissions (the default administrator on this folder only read permission), and then select the right mouse button WinSxS, general-"Advanced ..." – Compress content to conserve disk space. The compression process takes 10-30 minutes, depending on the performance of the hard drive.

After this three steps, look at your C-plate again!
