Hello everyone, I might sound like an idiot to you, but I've searched/read info about the difference between 32 and 64 bit OS-s and haven't really understood it. The only thing I've understood is that you can use more than 4GB RAM on 64bit. I will not ask you to enlight me their differences but I want to ask if there is any reason NOT to install Windows 7 Ultimate 64bit on my PC. Also, I would like to have the dll files I need to replace so I can install custom/unsigned themes (uxtheme.dll, etc.), and please don't send me the uxtheme patcher, I prefer to do it manually.
Even if you don't have 4 GB RAM, if your CPU supports it, you should install Windows 7 64-Bit. Any application that is not compatible with the 64-bit architecture will automatically be installed in the C:\Program File (x86) folder so you will never get compatbility issues. The only thing you *might* face is some drivers do not work unless you get the respective 64-bit version, but that is a very rare case as Windows 7 usually picks up all the drivers automatically.
If you don't know how to take ownership of the files as mentioned above. Lemme know and I'll post another guide for ya.
I know that one ;p Actually I found that one too on google, but it was posted when the beta was out and I was worried that it may not support build 7600. Also does it work with both 32/64 bit versions? And can you also answer my first question. Thanks for your help so far.
The difference in OS 32bit and 64bit are the calculations they can handle, more calculation more speed. A 32bit system can handle only till 4GB a 64bit system can handle up to 16GB. If you install more RAM than 32 bit system can handle you will not see any improvement. You will see something like this in properties: Installed memory RAM: 8GB (3.75 Usable) or less and maybe the PC will not boot at all. The calculation is simple: 2 ^ 32 = 4,294,967,296 bytes = 4,194,304 Kb = 4096 Mb = 4 gigabytes 2^64 = resulting in 16 exabytes = or to we understand, 16,000 million gigabytes! (this is nonsense lol) the majority of processors support 64 bits instructions... hope you understand
Correction, a 32-Bit OS can only handle 3.2 GB effectively. Even if it may show 4 GB. It can only utilize 3.2 GB
Thanks and yes I know, if you look at it again you will see i make and example (I was editing post wile you where making yours) lol but thanks anyways and for the record Although it is best to have the more RAM the better, can not install all you want. There are several limitations. The processor, motherboard and your computer's operating system can only support a limited number (and a specific type) of memory. 32-bit processors can only handle 4 GB of RAM, regardless of operating system installed. This is a physical limitation: the number of bytes that can be addressed (ie, assign each one a particular position). Although if processor support 64-bit (if 32, there is no doubt possible), the operating system can be 32 or 64 bits. In the first case, if the hardware allowed to install more memory, the system will be limited to 4 GB The board may limit in two different ways the amount of memory that can be installed. The first is through its chipset, which also affects the kinds of processors you can use. The second is by the number of free sockets on-board. To be sure, both of how much RAM you installed as the best way to do this, consult the manual for the motherboard or branded PC/Laptop.
