Whenever I try to install windows updates, i keep getting to errors. they are: Code 80070005 and Code 80070643.

Also, i am unable to install any softwear on my laptop. whenever to download some softwear, such as Skype, it tells me that i need permission to preform the action. I am the administrator on the laptop and the only one who uses it. I have never changed any settings and was able to download AIM when and softwear for my school for a while, but now I cant.

This is a reletivly new laptop, i got it in November from Dell with Vista Home Basic already installed.
