    RAM usage W8.1 versus W10

    I have compared the RAM usage of 8.1 and 10 in exactly the same (virtual) system. They are quasi identical.

    You must not be using ie11
    Otherwise it would be reading about 1300mb

    I use IE11 but I may not have used it before those screenshots were taken. I only wanted to compare a basic vanilla RAM usage. If you run other programs, it will be different again.

    I was using win-7 and had one ie10 window open and was soaking up 1300+mb
    Of course I'm sure mbam pro was really soaking up the ram :)
    Good comparison you made though but not allot difference between 8.1 and 10.

    Yes, there's not much RAM hunger difference between them. Though, there are some new services that I still don't know if they're important or not, but I'm trying to optimize the memory usage killing some useless things.

    I'm running Windows 10 Enterprise TP in real hardware, dual booting with Windows 8.1 Pro, on my wife's computer. All her data is backed up in my two external drives, so no fear about trying. I'm doing all daily tasks on it and except by the impossibility of syncing my two Windows Phones I feel comfortable and quite safe. I use Office, AutoCAD, CorelDRAW, some scientific software and all goes fine... by now !

    What I'm gonna say may be garbage, but playing COD-MW3 on my wife's rig I noticed that the OS keeps the game using less memory than when I play it on Windows 8.1 Pro. My current wife's rig is an old Phenom Triple-Core 2400 MHz with just 4GB of 800 MHz RAM coupled with a 128-Bit 2GB VGA, but the game keeps consistent performance using less resources.... I don't know if I'm right, but it looks like that Windows 10 has a better memory control.

    ~edit: off topic~

    After 1 day with Office 2016 Preview I went back to 2013 ! Except for the new color theme I didn't see much difference, and it doesn't activate with any 2013 legit key.

    I would expect that the memory usage of Windows 8 and Windows 10 would be quite close. But measuring this is in a modern OS is very difficult. There are many possibilities for factors other than those being measured influencing the results. The very different values for free memory leads me to believe that Superfetch is influencing the results, most likely due to different application usage patterns. There are other possible factors as well.

    Memory usage of an OS is influenced by many factors. Including how much RAM is in the system, what processes are running and what they are doing, what processes were doing earlier in the session, and more.

    One would imagine RAM usage would be trimmed down.

    I would expect more RAM usage, newer computers tend to have more RAM and it's usage (up to a point) is preferable over using disks for normal tasks. Part of W8/8.1 speed is due to using RAM to cache files needed for system operation insted of reading them from disks every time they are needed. Programs on the other hand, use as much RAM as they want and need, system is not too influential there.

    The system memory manager maintains control over application RAM usage. Applications allocate virtual address space, not RAM. The memory manager then allocates RAM to the application according to it's discretion, always with the goal of maximizing overall system performance. Applications can exercise limited control over this but it is rarely done and generally discouraged.

    Yea I don't believe whs is using a Microsoft account so many internet hungry services are null
    He does use some gadgets for monitoring goodies though and no telling what else ?

Hi everyone, I don't know if this is the right place to put this but it's been a while since this is happening: This PC currently have 8 GB of RAM after playing/watching a few videos/browising the ram suddenly goes up to 85-95+% (70-75% the lowest)...

Windows 10 resource usage in Installation and Upgrade
One of the good things is the small footprint of Windows 10. In my installation it uses only 8.5GB on the C partition and less than 500MB of RAM. I am sure that willl grow somewhat with the RTM edition, but it is a good start. 72517252
