what is the advantage of going to 64 bit.i have 32 bit win10 pro on my pc

All 32-bit client versions of Windows (not just XP/Vista/7/8/10) have a

4GB address space (64-bit versions can use much more). That's the

theoretical upper limit beyond which you can not go.

But you can't use the entire  address space. Even though you have a  4GB address space, most people can only use *around* 3.1GB of RAM. That's because some of that space is used by hardware and is not available to the operating system and applications. The amount you can

use varies, depending on what hardware you have installed, but can range from as little as 2GB to as much as 3.5GB. It's usually around 3.1GB.

Note that the hardware is using the address *space*, not the actual RAM itself. If you have a greater amount of RAM, the rest of the RAM goes unused because there is no address space to map it to.

The advantage of running a 64-bit version of Windows mostly exists only if you also run 64-bit applications under it. Bear in mind that there are very few such applications available yet. If you are presently running 32-bit Windows, you don't have any 64-bit applications, so to achieve any significant advantage, you not only have to replace Windows, but also your applications, *if* (and that's a big "if") 64-bit versions exist.

Also note that you will need 64-bit drivers for all your hardware.

Those drivers may not all be available, especially if some of your

hardware is a few years old. So it's possible that you might also have to replace things like your printer, scanner, etc.

So the answer to your question is that it may not be a great idea right now. That will undoubtedly change in the near future, as 64-bit applications become more available, but for now, 64-bit Windows often means some extra trouble and expense for little or no benefit.

On the other hand, installing 64-bit Windows instead of 32-bit Windows makes you able to buy 64-bit software as it becomes available, instead of the older 32-bit versions. That means that installing 64-bit Windows--even though it may do very little for you at present--puts you into a better position for the future.

One additional point: the 64-bit version lets you use more than the approximately 3.1GB of RAM that the 32-bit version can use. Very few people need or can make effective use of more than 3.1GB, but if you are one of those who can, that's something else to consider.

HI Bob. I'm Greg, an installation specialist, 10 year Windows MVP, and Volunteer Moderator here to help you.

32 bit can only address 3.7gb of RAM, so you're not using it all and can't expand it either.

To change to 64 bit requires a Clean Install so make the most of it by following the gold standard Clean Install in this link which compiles the best possible Install of Windows which will stay that way as long as you stick with the tools and methods given, has zero reported problems, and is better than any amount of money could buy: http://answers.microsoft.com/en-us/windows/wiki...

To create bootable Windows 10 Installation Media (on another PC if necessary) install Media Creation Tool and follow the directions in the middle of the download page here: http://windows.microsoft.com/en-us/windows-10/m...

Insert media, boot it by powering up PC while pressing the BIOS Boot Menu Key for your PC maker given in this chart: https://www.sysnative.com/forums/hardware-tutor...

If the media won't boot you may need to enter BIOS/UEFI Setup (pressing key given in chart in link above) to turn off Fast Boot or Fast Startup first.

Choose the boot device as a UEFI device if offered, then on second screen choose Install Now, then Custom Install, then at the drive selection screen delete all partitions down to Unallocated Space to get it cleanest, select the Unallocated Space, click Next to let it create and format the needed partitions and start install - this makes it foolproof.

Skip the Product Key if you have a Digital LIcense and it will reactivate when you connect to the internet.

Then run the Crucial System Scanner to check the RAM is properly spec'd and configured, what upgrade options exist for first quality RAM: https://www.crucial.com/usa/en/systemscanner?cm...

You will get and keep the best possible install to the exact extent you stick with the steps, tools and methods in the linked tutorial. It's a better install than any amount of money could buy and a great learning experience that will make you the master of your PC because you will learn everything that works best and how to apply it with your own hands.

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
