Windows 7 Highly Compressed

[torrentg]

Haha. That reminds me of a theoretical math example. How long will it take if you walk a mile at a constant 5 mph, only stopping for a minute every time you get half way there?

Hi all.

Getting away from Quantum physics etc etc there are some very good compression algorithms out there.

Now the first thing before using any compression algorithm is to ensure the data is in it's original state (i.e uncompressed). If you are starting with a compressed file then your compression algorithm won't be 100% effective -- for example say we have a simple one that merely counts spaces - the compressed file won't have any (probably) so your compression file won't be any smaller.

The next thing is to look for words and phrases which are very common per language. You can then devise some method for encoding these.
Then there's a whole slew of stuff you can do but you do need the original data BEFORE compression.

So for windows expand the CD say on to a spare directory . Now as a first pass just try running your archiver against these files.

The CAB files could be extracted and then try again.

I don't knw what the theoretical limit would be but given enough time and sophistication there could be some pretty good compression algorithms out there.

NASA probably would be a good possible public source for this type of info -- after all sending commands to its Pluto mission spacecraft which take maybe hours to reach the vehicle and hours to get a response would ensure that the barest minimum of data required to get the job done would be sent.

As for versions of Office -- there's a version of 2003 Office Lite (but Has the same contents essentially as the Student and Teacher edition of 2003) is out "in the usual places" highly compressed at 73MB (MSOFFICE2003LITE_Pronto) around 12:1 compression.

Windows 7 X-86 using the same algorithm at 12:1 could probably be squeezed down to 200 - 300 MB assuming original size is around 2.2GB (hope my maths is OK).

Of course you'd have to expand and convert back to its original format before installing but should be "do-able".

Cheers

Ok so I used to have the windows 7 setup but I accidently deleted it and it took me a while to download windows 7... it was build 7048 or 7057 I don't remember but I need help! I really want it againg and I need it to be highly compressed (compressed should be around 300-200mb) and that's a huge difference.... If someone can help me I would thank you a lot!

Search the warez sites, i have a copy of build 7000 compressed to just over 300mb.

@everyone saying its impossible, its not.

 

[Mercurial]

the people saying its not possible prolly didnt download enough warez... LMFAO. I downloaded God Father the game 430mb and extracted its setup to 6GB+ with winrar. and 280mb for NBA 2008 , how? who knows.... impossible? neh

As I pointed out - Commercial or public domain compression programs can achieve (in optimum situations) on average around 10 - 12:1 LOSSLESS compression. So your 300 MB could expand to around 3.5 - 4GB ( or more) depending on the quality of the original compression algorithms. A text or word type document might give you as much as 90% compression.

Why this stuff is causing so much mis-understanding I really don't understand.

I'd imagine a load of people on this board are of an age where an Ipod is an every day acessory. Typically you are listening to highly compressed AUDIO music encoded at say 128 kbs mp3. This type of stuff is much more compressed becuase it is "LOSSY" compression -- it doesn't have to be expanded to the original format again. So the compressed files can be very much smaller than the original files as you can throw huge chunks of the original source file away.

FLAC on the other hand is a LOSSLESS comprestion which is why the file size is much larger (can be up to 50% of the original so compression ration is only 1 : 2)

Same for Video -- the human eye can tolerate quite a large degradation in original quality from the original especially if its watched on a small screen so of course you can have much higher compression with smaller files.

Now for DATA such as Windows - you need the original Windows files to be re-creatable from the compressed file. This means that the compressed file can't be a LOSSY compressed file. - You need to be able to create an EXACT replica of the original data.

A much harder task altogether.

You can't compare compression of Video / Audio files with that needed by DATA files. (That includes programs, operating systems etc etc).

Putting maths etc. aside - I have tried a heap of these (because my bandwidth is precious), and not a single one of them worked, no matter what i did. On further inspection with a hex editor, the reason why these compress so small and become large when uncompressed is because the files are filled with blank bytes (00).

Ok then I really thank for your help... weird thing is that I downloaded windows seven for the first time a month ago and it was 340mb compressed and then when I uncompressed it, it was huge like 2.4gb ,,,,,,,,

So go to where you got it from in the first place cos I'm sure IF it was available in the first place then it will be highly sought after so still there.


I will never believe office was compressed to 13 kb:roflmao: And also you will never get a full working copy of seven at 2-3 hundred meg regardless of how you think compression works.

the people saying its not possible prolly didnt download enough warez... LMFAO. I downloaded God Father the game 430mb and extracted its setup to 6GB+ with winrar. and 280mb for NBA 2008 , how? who knows.... impossible? neh

Yeah but you should take into account half of the guts have been ripped out also, thats why they are called rips. I use warez more than most and the people who compress best are skullptura, shroo, toed and I can tell you a 2-3 hundred meg working copy of seven is not feasable. 13 kb office:roflmao:

I am talking about software used to compress the giant 2 gig setup and then uncompressed it

normal should be around 2.4 gig
and compressed should be around 230- 240 mb

get it?

No I don't get it and never will, your living in the land of make believe. It does not matter what you were talking about, compression at that rate of a full working copy of seven will not happen.

Get it? No did not think so!

And you don't understand warez. You just download it. They steal where you can't tell the difference. They take the uncompressed audios/pictures/video/textures (which are what make up the majority of the size in a game) and compress them. Then when they are "installing" the game, they reconvert those things back into the uncompressed form, with a loss of data, but you generally can't catch the differences (think about bmp to jpg, uncompressed avi compressed with xvid, wav to mp3). The problem is the majority of Windows or office isn't audio/pictures/video/textures/text. You aren't going to recompress their already compressed files to something crazy small.

And the mention of the 73 mb office 2003 install. That's a lite install, they ripped out all of the user content and created their own installation for it. It was different.

Stop trying to create the perpetual motion machine.

its real....

hey..dudes......its real oly.....i downloaded nfs most wanted from net which was oly 7mb....just google it....if you dont get i may post a torrent....and of course it is working....and there is another compressed file with me......windows xp 64 bit all versions.....compressed to 9mb....which when extracted ..came to a whopping 3.5gb.....i can post tat torrent too if anyone needed...i dunno the ABC of compressing....lol...

I still maintain it can be done, not really sure how i could prove it without linking to a warez site but i have tried a 300mb compressed version of build 7000 and it DID work. I didn't test it long term but it seemed fine. It just takes ages to extract.

I have also tried a <10mb copy of office 2003 that also worked fine.

It can and has been done.

 

[Sherifftruman]

I will never believe office was compressed to 13 kb:roflmao:

Maybe it was an Office 2007 Document. :sarc:

 

[win7]

Its on mini nova for all the doubters... 277.36 MB (not the 7000 i tried but 6801).

 

[fakeasdf]

I just downloaded the super compressed. Not only does it not pass the CRC, but stuff is totally pulled out of the iso So, if we consider pulling stuff out of the ISO a new method of compression, then I guess yall are right

 

[Ehoa]

I guess you're right but i know whatever the size (tiny) was , it took ages and ages to decompress , it wasnt connected to the net , and its working in full this very moment on a mates laptop ... but it all doesnt really matter now does it , like some have said , it cant be fully functioning , it must have integral parts missing and its probably a virus ...

Yes you are right there fakeasdf we must now consider taking things out of the original to be a form of compression.:sarc:

It worked and it being a *fully installed and validated* version of Windows 7 and / or office are 2 *entirely* different animals.

With vLite, for example, there were folks ripping out oodles of things from the Vista installer CD, and one guy had it down to 500 MB as a standard installer. As jimbo mentioned earlier the Office 'lite' version was the same thing.

But, with Student / Teacher, IIRC, you either don't get Powerpoint or Access, not all the other stuff like Infopath, all the templates and fonts and such - it is a *shaved* down version.

I just downloaded the super compressed. Not only does it not pass the CRC, but stuff is totally pulled out of the iso So, if we consider pulling stuff out of the ISO a new method of compression, then I guess yall are right

Exactly - anyone can claim til they are blue in the face that "I have one that works" _ but let's compare it next to the real thing and see what has been ripped out of it and how everything works or doesn't work - I've been at this for a long time, and unless you have a reason to use a cut down version (and in that case you're not really helping in the Beta test process - you start yanking things out you can rarely be 100% sure that any problems you encounter are not due to that missing stuff) there is simply no point.

If you have bandwidth problems, you can ask someone you know to DL the ISO. If you have no DVD writer, you can use alternate methods (boot from USB, mount ISO in VCD and perform an upgrade or a new install using the installer to partition your HD)....

Also, how many of you are security experts and can *guarantee* that the stuff that has been removed is not integral to having a safe and secured Win7 install? For example, if UAC has been completely ripped out, then you're just getting a faster XP box that needs 5 layers of security to work reasonably safely....

Yes you are right there fakeasdf we must now consider taking things out of the original to be a form of compression.:sarc:

Yeah, something the script kiddies seem to not notice or care for. "Wow, I got it down to 200 MB" = yeah, well, with the full 2.x GB install it installs in all of 10 minutes. And with my connection, 2.2 GB takes me under 30 minutes to DL....even with the speed of my processor, why would I even bother with a 300 MB unverified image?

Post it, I'll download right away.

Sounds to me like the uncompressed files are reporting the wrong size. There is NO way that 9MB will extract to 3.5GB, that's nearly 389/1 compression ratio & it's just not physically possible. I'm no expert on compression but i've been using compression programs since PKZIP was used in MSDOS.

Take the installation of Windows 7 for example. A 2.35GB DVD once installed will take up nearly 8GB, that's a 3.4/1 commpression ratio.

Ehoa just PM'd me a 2007 office file.. It's 1.5mb in compressed form and this program says it will be 440mb when completed. Not a believer?
