Note: Make sure to read the updates at the end of the post, with some clarifications and findings.
I use Windows since 3.11, with all its problems but also all its advantages.
I have a desktop PC specifically built, configured and fine-tuned for gaming and movies with Windows 7 (fully updated).
Here is a screenshot of how it consumes resources just after booting:
I killed the ATI Catalyst Control Panel to have almost only basic system processes, and also anybody can see that I have Aero disabled (and the associated service stopped). No Windows Defender nor any antivirus (only Windows Firewall).
This said, can you please explain to me how did you manage to get this Windows 7 screenshot and numbers?
Because it looks you are using almost half the memory I use, and this is a tunned Windows, clean as very few real PCs will be. For example, my development PC uses around 900MB just after booting. Probably any commercial one, which comes bloated with crapware and a antivirus will eat at least 500MB more.
So please, don't treat us like fools, because I can either laught or get angry at that dirty attempt to impress with "really low" numbers.
Ok, is about 30% less memory consumed, so leave it like that.
And if you include numbers, include real world ones, not utopic scenarios that nobody will ever see in the real world. Lying is bad, as we are all told when we are young.
Either that, or please explain to me how I manage to reduce by half my memory usage. Easy level, only on my gaming PC, no need to get into harder scenarios like my laptop, with SQL Server, Visual Studio and other typical tools that most developers will have installed ;)
Update #1: Just a small note. Both of my Windows 7 are 64 bits (gaming one is a Ultimate with mediacenter and other similar services disabled, laptop a Professional).
Update #2: x64 versions add significant overhead to each spawned thread, and can eat up to twice memory for each, so seems they used a 32 bits version to compare. Counting that <=3GB systems are dissapearing except for netbooks...
Update #3: Confirmed my multiple sources that Windows 7 scales memory consuption to a % of your available memory. In a 32 bits 1GB RAM machine seems that is easy to reproduce the slide values.
So then I was wrong in saying this is fake data, it is real data. But it is misleading, cheating and unrealistic data.
Excepting netbooks and maybe TabletPCs, most if not all recent laptops and desktop computers have at minimum 4GB of RAM, with quite some installed programs and services, so the scenario presented is not going to be the common case.And AFAIK I cannot disable this behaviour of adaptative RAM eating.
For me doesn't changes much because the only way I can get those really small amounts of occupied RAM is by actually removing RAM modules XD
But at least I've learned a few things, like the overhead that 64 bit threads have or this adaptative memory consumption pattern (which I would really like to disable or modify, I hate not being able to control this OS settings).
