If she doesn't have much on her computer in the way of large programs, something is weird here. How long have you had this computer and what is it used for? There is a cheap ($8) utility, called DiskPie Pro that will help you figure out, manage, and cleanup whatever is on the disk that may not be necessary. It's probably just an accumulation of innocent things and programs, but there is also a chance that her computer has been compromised by hackers who are using her computer to store their stuff. It might sound far-fetched, but it's increasingly common, especially if you don't have an effective firewall in place. These things are sometimes called "botnets" and it's estimated that about 5 million computers have been infected. I'll add a second post below with a link to a story on this. Here is a link that might be useful: DiskPie Pro

bus driver: The chances are you are not going to find any big files but if you look in the right places, you WILL find billions of small files. I wouldn't recommend loading anything else on your computer until you have cleaned the hard drive off a bit. 1: clean out your Temporary internet files. In IE that option will be under tools, Internet options. In Firefox it is under Tools, Options, Privacy. 2. Delete other Temporary files. Click Start, Search, All files and folders. Type TEMP in the first search box and click search. Anything in the Temp folders can be deleted safely. Any file with a .tmp extention can be deleted. A warning though, there may be some files that can not be deleted there as that is where most virus scanning software put their processing logs. Those will have a very recent date on them. Don't worry though, Windows will yell at you and tell you when it can't delete a file. 3. Go to control panel, double click "add or remove programs" a. Look through the list that populates for programs you no longer use and uninstall them. b. Look for programs that you don't recognize.. do a online search to determine what they are and if you think you don't need them, uninstall them also. 4. Empty your Recycle Bin. 5. Do a disk defrag. The default windows will work.. there are others that are better. Right click on your start button, click explore. Right click on "local drive (C:)" click on Properties. Click the second tab, Tools, Defrag will be the middle choice. Let us know what your disk space is after you have done that.

Just poking around in File Manager and the only icon that responds to right/click=properties is "computer". It appears MS has reduced the right click for properties as a use for all tool. I can't figure why. Slight diversion, I have started using my laptop computers as a laptop, not as desk top with remote keyboard and display. I now find that when typing, such as now, the display will suddenly transfer to another site/display. Or, the (just now it happened) I will suddenly find the typing has either stopped, or transfered to some other location on the message field. What's up, am I touching the touch pad with my hands, which are poised just above the pad? Makes me wonder if I can turn the touch pad off, and use a wireless mouse and not have trouble with interrupts springing up while I type.

I suggest she uninstall any unused programs and do a disk cleanup Start > Accessories > System Tools > Disk Cleanup. I use ccleaner but disk cleanup will get rid of some of the junk. She can then start the computer in safe mode by tapping the F8 key as the computer starts up. She will get a screen where she can choose to startup in safe mode. She can then right click on 'My Computer' click on 'Properties' click on the 'Tools' tab and check for errors by clicking 'Check Now' and then defrag by clicking 'Defragment Now'. This can be done without starting in safe mode but for someone who is new to the process I think this is the easiest way.
