What should I do if the Win7 system disk compressed volume can only compress half of the capacity?

The disk management tool that comes with Win7 system can effectively help us manage disks, such as compression and partitioning. But sometimes we will only compress half of the capacity when compressing the volume. The capacity of the partition can be imagined. How do you avoid this happening?

The steps are as follows:

1. Right click on the computer ”—— attribute, click on System Protection;

2, close protection Win7 system C drive;

3, the protection function is turned off, we will have to delete all restore points originally created, as shown below:

4, when the system protection is closed, after the restore point is deleted, you can compress the volume of the C drive of the win7 system.

problems do not want to be too complex, often very simple method. It can be seen that this method of solving Win7 disk compressed volume can only compress half of the method is quite good operation, also applies to win8 system.
