I recently changed companies I was working for and bought
out my computer. The company reconfigured my computer.
Since then I haven't been able to install new programs on
my computer because I do not have administrative
priviledges. How can I become the administrator on my
computer so I can install new programs? If anyone knows,
please help me!
