I have a legit 32 bit windows 7. I like to upgrade it 64 bit.

What is the cleanest way of doing?

it is not advisable to upgrade to 64-bit
becos a lot of software or applications cannot run in 64-bit browsers like Shockwave Player

is there like a 32 and 64bit version of Office?

Can I run 32-bit programs on a 64-bit computer?
Most programs designed for the 32-bit version of Windows will work on the 64-bit version of Windows. Notable exceptions are many antivirus programs.

Device drivers designed for the 32-bit version of Windows don't work on computers running a 64-bit version of Windows. If you're trying to install a printer or other device that only has 32-bit drivers available, it won't work correctly on a 64-bit version of Windows.

So, it is safe to run 64-bit Windows and still be able to run older 32-bit applications with no problem. But you'll need 64-bit software drivers for your hardware. Again, most hardware manufacturers provide 64-bit drivers for their hardware in the past 10 years.

Windows 64 bit provides transparent backward compatibility with 32-bit applications through its WoW64 subsystem. See: WoW64 - Wikipedia, the free encyclopedia

Yes, there is.

Source:

• Choose the 32-bit or 64-bit version of Office - support
• 64-bit editions of Office 2013

By default, the 32 bit version is installed for compatibility with third-party add-ins. However, if you don't use third party add-ins at all, it's fine for you to install the 64-bit version instead.

why do u need to run 64bit browser when a 32bit browser can work as it is?

so if i have 16gb ram? i will be using only 3.25gb?

good question, I am also keen in the answer

Generally speaking, "a 64-bit processor performs best with 64-bit software" according to Wikipedia. The WoW64 subsystem and backward compatibility may impose a certain level of overhead. Software compiled and optimized for 64 bit processor can run natively at full speed as it is with no backward compatibility translations involved, and to use the full size of the registers. As a grossly simplified example, a 64-bit processor can process (e.g. XOR) a 64-bit data block in a single instruction. When implemented as 32-bit program, the 32-bit program thinks the registers are still 32-bit, and thus has to break a 64-bit data block into 2 sub-blocks and perform the processing twice. I must declare that I'm no optimizing compiler or Intel x86-64 machine language expert, just stating a possible example scenario to illustrate my point.

Performance

For most users of desktop applications, the benefits are not so obvious. The power and flexibility of 64-bit computing are more apparent in supercomputing or large scale computing where large datasets are processed, aided by the larger memory address space and registers afforded by x64.

Security

Windows 64-bit is also more secure with hardware Data Execution Protection (DEP), Address Space Layout Randomization (ASLR), Kernel Patch Protection (KPP) and mandatory signed drivers turned on by default for 64-bit software. See: Why the 64-bit Version of Windows is More Secure

To help answer one aspect not covered. Running 32bits application within a 64bits system that have access to more than 4GB of memory is limited to that application only. That means if you have more than one 32bits applications running, the full 16GB of memory can still be accessed.

For most consumers, I don't think we have come to the point of utilising 4GB of memory for most of the applications. There are some niche applications largely of scientific or media content management such as Photoshop or Premier for example that uses beyond 4GB for its data.

Came across this by accident. Just sharing.

Dude, it just plain surfing internet. As long as u don't visit websites that u are unsure of. You are pretty safe.

For best compatibility, 32bit browsers works fine.

However, of course if u are using Adobe suite of products that optimized for 64bit. Its highly recommended that u use the 64bit instead of 32bit. If not, you might bump into those "low on memory" or "out of memory" issues.
