How do i increase space on my d hard drive

You can start by deleting files you no longer need or use and unistalling programs you don't use. You can also archive files you never use by burning them to a CD or DVD or even storing them on a flash drive. You can also use CCleaner ( http://www.piriform.com/ccleaner ) to recover some space.

Buy another hard drive. You can find 500gb for $65 or 1tb for $85. That's awesome compared to prices, even six months ago.

If not, then use a program that can identify all space usage and start deleting.

u can keep last stable recovery image/point... and deleting the old recovery image..

u can also try to back it up to optical disk for archiving or storage purpose...
or u can add new hard drive.....

If the whole drive lack of disk space you have to replace it with a large one, and you can directly migrate the OS to another HDD without reinstalling by AOEMI Partition Assistant, you can see this post: http://www.forumswindows8.com/aomei-partition-software/...
