Reduce Vista's harddisk usage/ReduceThe Area Reserved For System Restore In Windows Vista

In windows vista the system restore feature is build in .It really helps when our system get corrupted.Usually the system restore feature takes 15% of the total hard disk space.We often doesn't care about it. But after a prolonged time it matters.Imagine that you have a 500 GB hard disk. With in few days the system restore feature will eat upto 75 GB of the hard disk space.So it really matters.There is no option in Vista to change the space reserved.So we need to provide some commands to do it.
Got to start and type command prompt.You will see the program.Right click it and select Run as administrator.
Type the following commands.

"vssadmin list shadowstorage"

Next we need to change the space reserved.So type the following command.

vssadmin resize shadowstorage / on = C:/ for = C:/ maxsize = 10GB

Here C is where your Vista has been installed.If it is installed on another drive change it accordingly.That's it you have regained approximately 65 GB on haddisk space.
