Just finished the win7 system, how to be thinner

The system just finished loading and want to lose weight on the C drive, it is very difficult, but there are still some ways to reduce the space occupied by the C drive, so that your C drive has more space available. Of course, if you have already installed a lot of systems, you can use the following methods to lose weight.
1
Change the virtual memory location
The virtual memory is on the C drive by default. The occupied space is about 2G. If your computer has more than 4G memory, you can directly use virtual memory. And if you want to use virtual memory, you can set it to other disks.

Setting the virtual memory process:
Click Start, right click on the computer, select Properties, switch to Advanced, and then the settings below the computer properties.
Switch to the pop-up window, Advanced and then click on the changes under Virtual Memory.
It would be fine to move the C drive to the D drive.
3
Turn off the sleep function
Hibernate mode will store the current state of the system in a file, and if we close the sleep mode, there will be no such file. So the shutdown is still to be closed.

Sometimes you need to use the sleep mode, you can't always set it up, you can use the following method to quickly turn it off and on.
Copy the code below, paste it into Notepad, and save the file as closed hibernate.bat
@powercfg -h off
Copy the code below, paste it into Notepad, and then put the file Save as to enable hibernation.bat
@powercfg -h on
When we want to turn off and turn on the hibernation function, we only need to run the above two bat files as an administrator, which is very easy!
It is about the win7 system that has just been installed, how to be thinner, through the above settings can release the C disk space around 3G.
