How to reinstall window 7 home on one partition?

Un-installed a program that Im now unable to reinstall? Freaking out! Help?!?

• I went to Best But the other day to buy a headset for my new class online. One of the guys there helped me set it up on my laptop. He said my computer was running slow and that I had a lot of unneccessary programs on my computer. He pointed out HP printer things that I didn't need that could be making my computer run slow. So when I got home I deleted somethings from my computer. HP photo shop etc. etc. I noticed right away that my scanner stopped working on my printer. An error box keeps coming up saying that my file isn't correct or something? To uninstall then reinstall.. So I have done this twice now and it is still not working. I'm freaking out cause I need my scanner . Ideas please. Window Vista HP Officejet 6310 All in one series.

• Answer:

  If you have the software CD, my suggestion is to download the free revounstaller program. just do a websearch for the site. it's very popular and does a thorough removal. it sounds like you didn't get the software all unstalled. and I hope you didn't DELETE the software, but just uninstalled. After running revouninstaller, you should be okay to reinstall the program. And.. be careful when salespeople tell you things to do.They're not computer wizards. I also have an HP printer and there is a lot of software that it uses to print and for the scanner. If they run at boot time, you can always rightclick in the tray (lower left of screen) and stop them. good luck.
