How can I recover my 64 bit processor, help plz?
I ran a 32 bit vista premium over my 64 bit vista home, how can I get it back to running 64 bit processor speed, I tried to install a windows 64 bit upgrade over it but nothing. I read on internet that I cant get my 64 bit back that way. Can anyone tell me how I can get my 64 bit back fully, do I have to buy a premium 64 bit upgrade and put it over the 32 bit upgrade. Please someone with intimate computer knowledge please help. Thanks

64bit isn't something that you "get back" - it's something that you have and the software either uses or it doesn't. A 64 bit operating system is a start.

Yes, I agree with 64bitfreak, leo's talk is good no doubt as far as explaining some of the basics about OS and CPU relationship is concerned. But unfortunately it does not answer to the origianl question i.e; "64-bit windows Vs 32-bit OS from security and safety per se" is not correct.

Many viruses are written keeping in mind the addressing scheme of the OS. Of course, a 64 bit OS would be more secure than a 32 bit OS because a hacker has more to crack.
In a bit more detail, I would like to say that viruses are all about manipulating numbers and performing arithmetic operations using pointers in a non-formal way, and that's why they can attack the the memo0ory locations.

Yes, bit ness of a OS of course matters in terms of secuirty from viruses.

This guy has absoultely no idea what he is talkin about. In order for a virus to work on a 64bit operating system it must be specifically encoded for 64bit. I could give a much better explanation than leo on this subject. WOW64 is written so that viruses that are written in 32bit mode cannot infect the 64 bit kernel of the operating system. Also, must companies are offering 64 bit drivers. LEO=dumb
