how to upgrade to windows 7 home premium

i had windows 7 home premium 64 bit(original) on my laptop but then someone installed windows 7 ultimate 32 bits(pirated) i want my original windows back and i just have the product key written on the back of my laptop
plzzzz help me ASAP...

What make of notebook? It should have a Restore partition on the drive. It should of also had some type of utility to create a set of system disks but that may be gone now.

In any event you can download the correct version from My Digital Life website and use your key on that sticker to reinstall.

Everything you need to know is right here,

Someone installed ??? Someone ??? How did you let this happen ???

Or were you the someone ??

Follow the suggestions above and you will have no problems. Ask questions b4 you begin and read the tutorial thoroughly.

We always assume you have made your Recovery Disks using the OEM manufacturer's Recovery Media Creator app the first day you had your new PC.
& made the Startup Repair CD.

Did you make the OEM manufacturer's Recovery Disks?



You can order OEM Recovery disks from your OEM manufacturer's website.

i was having problem of memory dump recently so someone said "its becoz u r using 64 bit"....thats why he installed this 32 bit version.

Then it was especially idiotic to install a pirated version just to get 32 bit, since you're entitled to use either 32- or 64-bit with the Home Premium Key on your COA sticker attached to the machine.

The consolation is that you will get and maintain a perfect install if you follow the steps in the tutorial. Ask back if you have any questions, and keep criminals away from your PC.

I suggest you never listen to that person again when it concerns computers, Operating System for computers, Memory management for computers and for the software installed on computers.
He clearly knows nothing about any of the above. And what he may know will only get him and anyone he tries to help into trouble, as you have found out.

now i have got a windows 7 64 bit reinstallation dvd(from dell) from from one of my friend also having the same laptop.
I wanted to ask that will this dvd work for my pc too??
