Hello. My sister is going to Munich, Germany this week. I formatted her laptop with Windows 7 Ultimate Pre-activated with validation check. But I wanted to know that if I send laptop with her is there any problem may occur in there ? I mean problem will SURLY occur or just chances are there (may not occur or may be) ? My sister have bought HP laptop with HOME PREMIUM edition. There is a product key written on sticker under laptop. But when she bought it the shopkeeper didn't gave her original DVD of SETUP. She mistakenly lost bill of the laptop also. The duplicate copy of bill can be taken from records of the shop. Now I have questions on that : 1] Did she bought Genuine home premium with laptop? if yes then, 2] The shopkeeper had to give original DVD of SETUP of the edition? if yes then, 3] Can we contact Microsoft and ask for the SETUP by giving them the product key? If the shopkeeper didn't/couldn't give us the DVD. Thank you.
