“and if Microsoft knows that this new OS performs better on a 64 bit, they should not have promoted the 32 bit or at lease tell everyone if you do not have modern processors, expect poor performance…”
I have quoted from a post in the MS Community, but I will not disclose the original author because he is wrong..
Question.. My Toshiba Netbook is fitted with a 64-bit compatible CPU, so why don’t I run Windows 10 in 64-bit form?
Answer.. The Toshiba Netbook’s motherboard had total RAM limitations of 2Gb which is NOT ENOUGH to maintain a 64-bit OS AND run other stuff on it. So Toshiba pre-installed 32-bit Windows 7 Starter and only supplied 32-bit drivers.
Running a 64-bit OS that has little or no driver support is NOT fun, so I never did it, and the upgrade to Windows 10 is also 32-bit, and the poor little netbook does well to run it as well as it does. I am pleased with it anyway..
To be honest, 4Gb RAM is cutting it fine for 64-bit too. While it can move larger chunks about, it does require more RAM to do it, even when its shifting 32-bit sizes around. It doesn’t come into its own until these 1, 2 and 4 RAM totals are passed by.
Question.. Why are there 32-bit programs in a 64-bit OS?
Answer.. Because for the amount of data which needs moving in most programs, 64-bit would be a complete and utter waste. For programs that have to move large graphics and data, 64-bit comes into it own. For the record, converting a program from 32 to 64-bit takes a lot more work than you think..
Utilities are slightly different. System utilities have to be 64-bit if they are to work within the 64-bit environment, but utilities like Java which run inside a 32-bit browser don’t have to be 64-bit.
As per the OS, 64-bit stuff uses more resource than its 32-bit counterparts, so unless there is a good amount of free resource, ‘all’ 64-bit would not work for you even if you could get it.. 🙂
