Upgrading Windows 7 32 bit to 64 bit

I have lots of clients with 32 bit Win7.  Never a problem.

Hello, I wanted to know how do I upgrade my PC  to 64 bit with windows 7, Because 64 bit supports many things, and I really need help finding out how.

32bit > 64bit is not done by any upgrade.

It is done by a clean install.

Retail Windows 7 licenses can use either 32bit or 64bit (but not both at same time).

OEM licenses are for the bit architecture that they are bought with.

If you want to change it, you have to buy it.

It requires a clean install of the operating system.

Save all your data and be prepared to reinstall all your 3rd party programs.

Then do a clean install:

But before you attempt it, check with your computer/laptop manufacturer to make sure that they support and supply 64bit drivers for your machine and for the edition of Windows 7 you are licensed for.

Also check your computer specs to see if you have or can upgrade to at least 4GBs of RAM, as without at least 4GBs of RAM you are wasting your time installing a 64bit version.

Or it may be easier for you to download the Crucial Scanner which will tell you what is the matching RAM for your Motherboard and the max. amount of RAM your Motherboard can accommodate.

Bill has advised you correctly.  Doing this is not easy and you have to ask yourself whether it is worth it.  Here are some facts:

1. Although there are programs that will not run in a 32 bit system, they are not common
2. If you install 32 bit in one system (4 G memory) and 64 in another identical one, you will see about 15% better performance in the 64 bit installation
3. The biggest benefit moving from 32 to 64 is in its ability to use more memory.  Chances are your system has 4 or less gigabytes.  To get the benefit, you are going to have to buy more memory and depending on your current configuration, you may have to replace what you have.  Not cheap.
4. If your system is elderly and your motivation is games, your system will generate more heat and power demand and your system may not be capable of that.

Interesting topic but the OP does now seem interested to get a Used Retail license.

My previews experience with  XP Pro 32bit, this was that with 4GB of ram I was unable to get in Safe Mode.

But it was ok in normal mode.

Therefore here is my question : Does Win7 32bit suffering from such a limitation?  

My joy with Win 7 Pro 64x regarding  memory & hardware compatibility, this is that now I am no more restricted due ancient OS 32bit limits.

Before you go and do what you were told to do, follow the information I gave you:
