If you use Microsoft Office, you could uninstall and install openoffice.org instead. It is equivilent and compatable but uses less space and can be installed on any drive/partition (MS office only likes C drive)
Better: With the low prices today, why don't you replace the hard drive with something larger, reinstall the operating system, put the original drive in as a secondary drive to recover anything needed from it, the format it and use it as a back destination for all of your important files.
I did this and when I decided to replace the computer anyway at a later time, all I did was move all of my files to the new computer on this drive.
oops, scratch out that last part, I just realized that this is a netbook (I got distracted) sorry.
