Consumers can download the Release Candidate build of Microsoft's slick new OS, Windows 7, and try it out for themselves. Both 32- and 64-bit versions are available for download.
Consumers can finally get their hands on a near-release copy of the latest version of Windows

Windows 7 has the tech community and the consumer world buzzing.  For consumers, it has been a long four months since the release of the Windows 7 beta which saw hundreds of thousands of downloads.  Some turned to torrents to try to swipe the newer beta builds or the recent Release Candidate, but for most it was a matter of waiting.

The waiting is over at last as Microsoft has officially released the Release Candidate 1 build of Windows 7 to the general public.  The build is available directly from Microsoft for download.

Microsoft is suggesting that novice users not download the build as no tech support will be provided.  Customers who download the build will have to burn the ISO onto a disk.  Unlike the more recent beta candidate builds, the RC1 build requires a complete reinstall, even on machines with a working build of Windows 7.

Both 32- and 64-bit versions of the build are available.  Microsoft recommends users' computers have at least 1GHz processor, 1GB of RAM and 16GB of free disk space.

Microsoft is promising not to limit the number of downloads of the new release, like it initially did for the beta release (before later relenting and allowing unlimited downloads).  The beta release proved a headache for some, as the large demand crashed some of Microsoft's servers at the time, rendering many eager users unable to download the beta from Microsoft.  Microsoft is hoping that this time around things go more smoothly.

The test builds of Windows 7 will work until June 2010, but starting in March 2010 they will shut down every two hours.

Microsoft has publicly stated that Windows 7 will launch "no later than January 2010."  However, it now appears that the new OS will land in time for the holiday season, as Acer has leaked its release date as October 23.

Hello,
I installed the RC release on my dv9207us HP laptop. It was error-free. It is definately the way Vista was supposed to be. The new task-bar is good.
It allowed me to install and run MusicMatch Jukebox that Vista did not allow.
WMP12 plays divX, DVD and VOB files. It still takes around 7GB of HDD.

Ravindra.

Also remember that this is the 'Ultimate' edition... This is theoretically the 'big boy' of the line.

For reference, check the DailyTech article on Windows 7 editions (http://www.dailytech.com/Updated+Windows+7+Edition... ).

The footprint should be much smaller for the OEM Starter edition ... which should make Netbook owners pleased. The lowest retail edition, Home Premium, will probably still require the lion's share of Ultimate's footprint... however any computer modern enough to be loading Windows 7 on should have sufficient HDD space.

I believe the way Microsoft was going to do it was to ship all the Windows 7 discs will all the versions on it and what features you get are dependent on the lisence key you enter. I had read that they wanted seamless upgrading from one version to another and this would enable that.

Yes, all disks will have all versions, it doesn't mean that all installs will be the same. Win7 x64 is a 3+ gig download whereas Win7 32bit was less than 3gb. The more goods you want means larger footprint. Take features away and you hd has more empty space.

Haha, I was thinking the same thing since Microsoft's download page gives the following requirements...

1 GHz or faster 32-bit (x86) or 64-bit (x64) processor
1 GB RAM (32-bit) / 2 GB RAM (64-bit)
16 GB available disk space (32-bit) / 20 GB (64-bit)
DirectX 9 graphics processor with WDDM 1.0 or higher driver

7 is much better than 16 even though space is a non-issue for the general public.

Makes sense, around a 3GB initial footprint with another 3-4 gigs reserved for paging and hibernate files.

Personally I disable paging completely, the average user will probably never need it with 4GB, and personally I have 8GB of RAM, and I have never even come close to the limit, even with some intense video editing. ok.. intense amature video editing ;)

Turning off your pagefile is a bad idea regardless of how much RAM you have. Saying you'll "never need it" shows a lack of understanding of how windows memory management works.

You are essentially forcing your computer to consume usable RAM for memory allocations that are never actually used.

Foolishness.

Ok, I don't actually totally disable it (I find you need 512M, mainly because some older programs require a page file, and for a few reasons I will mention below), but its damn close. Unlike XP which indiscriminately used whatever memory was available, whether it be paged or not (resulting in thrashing) Vista/7 specifically tries to load as much into the system memory as possible in the first place. The only reason Microsoft recommends to at least match the amount of physical RAM is because it is required to do a full memory dump. I've never done this in a home environment in my life, and I still have enough virtual mem to perform a mini dump, or capture blue screen errors.

I've also heard claims that it helps with managing the loading and unloading of applications, but I have yet to see a negative impact with only 512M RAM.(as I will mention below it is quite the opposite). That being said, your most commonly used programs are already in system memory because of superfetch, pretty much rendering your point about 'forcing your to consume usable RAM for memory allocations' moot as this is already default behavior.

By definition paged memory cannot be as fast as system memory, there will be a negative impact on your system anytime virtual mem is used as a subsitute for system memory. There is no getting around this, and while Vista/7 tries its best not to do so, I found that it would do so anyways on a regular basis. Although not nearly as bad as XP.

There is no doubt in my mind that going to the minimum page definitely speeds up my system, and while I would never attempt this at work, there is no reason to have a full fledged page file with 8GB of RAM at home.

P.S In the unlikely event Windows somehow does run out of memory with 4GB+ of RAM, Vista+ has a feature (which interesting enough is called RADAR or Resource Exhaustion Detector and Resolution) which will shut down the program using the most resources, so the days of XP where your system would become completely unresponsive are gone.

All your memory in any modern operating system is using "virtual memory". Virtual memory is NOT the same thing as the page file.

They are directly tied to one another, using virtual memory implies that the page file is being used. Notice how they say increase the virtual memory and not the page file size in the text below.
quote:
If your computer lacks the random access memory (RAM) needed to run a program or operation, Windows uses virtual memory to compensate. Virtual memory combines your computer’s RAM with temporary space on your hard disk. When RAM runs low, virtual memory moves data from RAM to a space called a paging file. Moving data to and from the paging file frees up RAM to complete its work. The more RAM your computer has, the faster your programs will generally run. If a lack of RAM is slowing your computer, you might be tempted to increase virtual memory to compensate . However, your computer can read data from RAM much more quickly than from a hard disk, so adding RAM is a better solution.

Not necessarily. You could have a virtual memory system that doesn't use a disk page file. I would guess that this is exactly how Windows operates when you completely disable the page file.

Also, the OP is right - Windows always uses virtual memory. For example, as an application increases its memory requirements, Windows will map more and more memory into that process' memory space.

The quote you gave is really for non-tech end users; it is a simplified and not totally accurate description.

Not really. You will only run into problems if your current memory usage requirements exceed your available physical memory. If you have, e.g., 4GB of RAM and just run a handful of non-memory-intensive apps, you'll be just fine.

I've run machines for long periods of time like that and didn't run into any problems. But on the other hand, I never noticed any performance difference, so when I reloaded the OS again, I never bothered with that.
quote:

What does that even mean? Memory is only allocated in the first place when a program requests it. So, by definition, if the memory is being used, then it is needed!

If that was the way it worked in practice that would be great, but in XP there is a lot of hard drive activity (thrashing) with the page file on as opposed to off even before it's used all your available physical memory.

I'll agree that the 32-bit base install (I'm another TechNet subscriber) on my 2500+ Barton test system clocked in at 7 GB of system HDD space. Note that this includes the 'system controlled' swap file probably based on my 1GB of RAM ... and possibly a hibernation file (don't remember if I hibernated once before checking the disk usage ... and if it keeps the hibernation file on the drive).

It was a nice clean install. My AGP nVidia 6600GT is running Aero fine. GUI is pretty responsive. Boots were pretty quick for a system that isn't that far beyond the minimum specs. On a non-technical side ... Microsoft included some *stunning* American landscape photos. Ultra-crisp even on my older 1440x900 panel. I haven't done much testing beyond that...

My I ask how much RAM you have? I've noticed RAM use differs from machine to machine. Makes me think there is some kind of formula to figure out how much RAM superfetch is to use. (which would be very smart).

P.S throw out everything you knew about 'RAM usage', as with Vista it is not the same as in XP. Superfetch will load your most used programs into memory so they will start almost instantly should you choose to use them.

If you have the RAM why not use it? Its not clear cut like 10 years ago, if you were to disable superfetch completely on a Vista system and a 7 system, you would surely see less resources being used in 7, and nowhere near the 700M you have described. (I've tested this myself)

In Vista I disabled prefetch entirely (via Regedit) and I was quite pleased with the results.

I'm running a gaming rig with 4GB of ram and vista would eat up 30% on boot (over 1GB), then each day it would ramp up until 90% was being used. That may be great if i could control what was fetched, but i cant...ideally I'd like to see it fetch my web browser (currently Chrome), my video player (VLC) and the last game i played (drakensang).

Instead it was out there gobbling up all sorts of ram for MS apps and other junk, then as soon as I'd start a game it would take massive swapping before it could actually cache my game...this was a real performance killer, so it's disabled.

When will smartfetching arrive on windows?

Thats not normal behavior in my books. Sounds like a memory leak to me, and chances are it is one of the programs you are running, and not Windows. And just so you know, Chrome has been known for its mem leaks in many situations. Especially if you leave the chrome windows open, while their cleanup efforts when you close a tab are amazing when compared to IE and FF, they have a long way to go with leaving windows open.

P.S on your 'smartfetching' comment, that is exactly what it does. Its not going to load a program into memory that you use once a year. If you use Chrome and VLC on a daily basis, these are surely the programs that are getting priority. Prefetch was XP, Superfetch is essentially a 'smart' approeach to Prefetch

It may be a memory leak, in windows, because it behaved that way since i installed Vista Business 64 (and on Vista RC2, and on Vista Beta). I haven't tried re-enabling superfetch since the service pack got installed.

Also Chrome was not installed when I disabled this feature. At the time I was using IE7.

What I meant by "smart" fetching, was the ability to designate which apps got fetched instead of Windows arbitrarily deciding for me. Like a memory manager.

//i'd like to think i know what I want a little better than windows does...

for example, fetching web browsers that load in less than a second anyway doesn't make a difference that's distinguishable to the naked eye.. fetching a huge ass game on the other hand can be very useful (and noticeable)

for another example. say I play fallout3 every day for a month. Windows says hey, the user has run this game 30 times, lets fetch this game. but on day 31 I install a crysis and stop playing fallout. it'll take weeks before windows realizes that i no longer play fallout and move on to crysis, when I knew it on day 1. hell, it owuld be nice if "smart" fetch even had an option in installer to make the new game your default fetched game.

really i see it needing default browser, default player, default game, and maybe default word processor...
of course every user wont need every category, and some may want two options for one category, but let the educated user choose if they want to.

I doubt there's a serious memory leak in Windows itself. Much more likely to be in one of the loaded apps, services, or drivers. Can't you see the leak when you look at the memory allocated to each process in the Task Manager or Resource Monitor?

NO, you couldnt see the leak (no apps were using more than 100MB in taskman). But disabling super fetch immedieatly solved the problem.

Who knows, it could ahve been fixed in SP1, but i'm happy without superfetch.

I don't really get the downside with Superfetch, since it is just using unused RAM anyway. If applications need the RAM, then Superfetch doesn't use it, and the application uses it instead. I'd rather have at least some marginal benefit from unused RAM, rather than no benefit at all.

To add on. On the 64-bit version of Windows 7, Chrome with default settings is broken.

You need to add some instructions. Copy/paste from Google.

The fix for launching Chrome from its icon:
1. Right click the icon and select Properties
2. Select the Shortcut tab
3. Add a space and --in-process-plugins to the Target field, after …\chrome.exe"
4. Click OK

Note that this fixes Chrome to work with x64, however I get periodic faults with pages not loading and have to refresh to fix the problem. x32 works flawlessly.

Superfetch works by using "unused" ram for apps that u used the most, its not stupid, but of course it wont know exactly what u want it for. But in the case of loading a game, no memory is "swapped", its directly overridden as soon as the app needs it. There are no performance hits to having it enabled.

No.. it bypasses the Windows Mixer allowing for bit for bit reproduction of the audio in question. i.e if you are listening to a 44khz/16bit MP3, it uncompresses the file to PCM and outputs that PCM audio bit for bit. By doing so, it locks out all other apps from playing sound (including windows sound).

The problems lies with the fact that you can have multiple programs outputting sounds in multiple formats, and Windows needs a way to join the all together. Previously in Windows XP all sound was resampled(and even Vista in non exclusive mode) to 48KHZ regardless of what is being played. So if you have ever wondered why your CD sounds different on XP (and most other OS's for that matter, as most follow a similar approach) than on your CD player, this is why. Your 44.1Khz CD audio is being converted to 48KHZ before output. To make matters worse (in XP) sound volume was tied to the bitrate, the lower you go, the lower the bitrate. This had the potention to vastly decrease sound quality.

Even Vista has many of these problems, although audio is dealt with in a totally different way (which I am not going to discuss right now)

In comes Exclusive mode in Vista, which completely bypasses the Windows Mixer and passes the sound untouched for output..
The only problem is it must be specifically coded into the application (Foobar has an WASAPI output plugin available for download from their site to take advantage of this).

It is essentially the same concept as kernel streaming in XP, although this feature is native to windows. Many soundcards also have special ASIO drivers too which do the same thing, although exclusive mode is a lot less buggy then both. I have had many system crashes in XP due to kernel streaming in particular.
