The only serious problem I had with Windows Vista was that when my hard drive went bad and I installed a new one, the original Vista CD’s I had from Microsoft would not work. It kept saying the product code was not correct!
After a hundred calls to Microsoft, none of which solved the problem, their US office finally transferred me to their guru’s in India. Those Indians installed Vista on my computer remotely via internet and gave me a new set of authorized code numbers to authenticate my software. My software is working without a problem. Those guys in India were the best I have ever come across, in terms of knowledge of Microsoft software.
When you compare the best to the best, the Indians may very well have the edge.
