Doubts about to Buy Windows7

just give up all the confusion it is reliable and strongly secured.

 

64 bit OS support huge memory. 32 bit support only 3.5 Gb of memory and you can see in windows 7 - 4 Gb with 32 bit OS but that system use only 3.5 Gb.
Yo can not upgrade 32 bit system to 64 bit and reverse.
I think that windows 7 DVD come only with one of version system (32 or 64 bit) because I use Windows 7 at work and often install that OS on other PCs with two DVD, one 32 - second 64 bit version.

For me the best OS is Windows xp - forever. I use Windows 7 but also have Windows XP - dear to my heart
Sorry about my bad english.

 

Hi, I have DELL laptop i3 processor, 4GB RAM and window 7(64 bit). I'm using this from last one year and I haven't faced any problem related to window7. I would say that I got this suggestion from helppconline (online tech support company).


and about OEM, I believe that the OEM version can only be used once and has no tech support from MS. The retail version can be installed on multiple computers (one at a time). This means you can install, then uninstall, then install again on another computer.


Thanks
