Download Windows 7 Home Premium Oa Acer Aspire

I have bought an Acer 5740 laptop that comes with Windows 7 Home Premium. When I install using eRecovery, it installs the Windows and is automatically activated, but it installs a lot of other software that I do not need. So I decided to download Windows 7 Home Premium image and install it using the CD key supplied with the laptop (on the back), but when I try to activate it it says 'The Windows 7 Home Premium key you typed is invalid for activation' and it gives me an option to activate using the automated phone system.

Windows 7 Forums is the largest help and support community, providing friendly help and advice for Microsoft Windows 7 Computers such as Dell, HP, Acer, Asus or a custom build. I know I'm gonna get slammed for this but the whole Tutorial baffles me.

I wanted to know why can't I activate it? Does this mean someone else might have activated it? Or is it because of the copy of Windows that comes in the hidden partition? Nokia asha 308 latest firmware download.

I have also read in one forum that you have to buy a Windows CD from Acer. Please advise.

Can anybody advise on reinstalling windows 7 home premium 64 bit without disc on my laptop which has had the hard drive replaced. Background: my child knocked my laptop from a table and it died kept getting BSOD ETC. I left it into a repair centre and was told it was an intermittant problem with either hard drive or mother board and not worth getting fixed Rang insurance company and claimed under accidential damage cover,they said they would pick it up and try repair it first,so they duly picked it up and rang a day later and said they had replaced the hard drive on it and as the software is not insured on my policy I would have to reinstall my own operating system. My laptop is an Acer Aspire 5742 i3 only 13 months old - out of warranty Acer wanted about 70 Euros to send a new disc to reinstall windows 7,the laptop came preinstalled with no windows disc. Sorry for the long winded story but my questions are: origanally when prompted I made recovery discs 1,2,3 and a repair disc.

Office 2010 installer channel switcher. Can I reinstall onto a new hard drive from these discs, the windows product key sticker is on the underside of the laptop. ANY ADVICE WOULD BE APRECIATED THANKS.
