As we all know recently Microsoft released SP1 Beta for Windows 7 and Server 2008 R2:

You can either use Windows Updates to download and install SP1 Beta or can manually download the whole setup file and install it later.

But there was a big problem in downloading the whole setup file as Microsoft combined both 32-bit and 64-bit versions in one package so it was hard for people to download a 1.5 GB file.

Now the good news is, Microsoft has made available separate download packages for 32-bit and 64-bit versions of SP1 Beta so now you can download them separately according to your requirements.

Just head over to following link and download the new download files if you have not downloaded them yet:

There are no changes in the content of packages, so don't waste your bandwidth if you have already downloaded it in past...
