Windows 7: Which windows uses the most RAM?

The title says it all.



Which windows uses the most RAM and CPU?

Windows XP or Windows 7? Which one of those uses more RAM?

Discuss.

vista uses the most.

win 7 uses more because of superfetch, so all unused ram it utilized to speed up the system whereever it can. But dont worry, when you need the ram, it will free some up for you

unused ram = pointless. So win 7 takes advantage of it

Basically Windows 7 uses more RAM?

I checked out the usuage and its pretty high. Maybe Windows XP is good in RAM after all?

Yes, the Windows 7 kernel uses more RAM by default than all other Windows OSes.
Windows XP is probably the best performing operating system.

Question should be "Which Windows makes the most use of RAM?".

The thing is Windows XP can be customized like Windows 7 and uses lesser RAM.

Windows 7 decides for you

winxp lets you decide

Windows 7 more efficiently makes use of RAM...that's an accurate way of stating it.

With Windows XP, the machine didn't cache things into RAM, it just left it wide open and it showed as free. And people were aware of how much free RAM they had and made efforts to try to maximize the amount of free RAM to ensure that apps ran the best they could and had the ram when they needed it.

Modern operating systems like Linux and Windows Vista/7 don't just leave RAM lying around unused. Instead, they keep as much in RAM as possible since RAM is the fastest way to get data. It's always faster to pull from RAM then your hard drive....even if you have an SSD drive.

Why have 8GB of RAM and ensure that 6GB of RAM is free? That doesn't make any sense. If you have 8GB, why not use 8GB.

And when an application needs to have RAM to run properly, Windows just writes over anything that was cached in RAM.....this isn't a performance hit to your user experience.

And Windows XP is now 8 years old, has fewer features, has less eye candy options, etc. I mean, Windows 3.1 took even less RAM then Windows XP....but people aren't still using it.

At the end of the day, RAM is plentiful and cheap. It's one thing that people generally tend to simply overbuy simply for the sake of having extra because it is cheap.

Windows XP isnt really old. Many companies and etc still use it. Even vista

Everything what gets released windows XP is supported.

The OP did not ask about Vista so no idea why you said that.

XP wastes Memory, it sits and does nothing.

Vista and Win 7 cache unused Memory (not the same as the Actual Memory usage you will see in a Gadget Meter or Task Manager), this preloads your most used Programs/Apps so they open faster.

If you start up a Game/App that need Memory they both let go of it immediately to run that Game/App.

Windows XP uses less Memory is stupid, it is a waste of time sitting there doing nothing when it can be used.

Also something above about XP and support, hate to tell you but as from April 2009 XP is no longer supported by MS its basically dead and will only get Critical Updates.
