Windows 7 Super-Nano Lite
Created by blzos and Modified by AThePetrov.
This Windows 7 ISO has been reduced to a mere 321 MB!
Build Year: 2019-2021
Version: 6.1 7601
Developer: Microsoft
Build author: blzos
Platform: x86
During setup, choose English US for language, keyboard and region. No activation is required.
Note: you may need to have additional drivers for your specific computer (Windows 7 Build 7601, 32-Bit) because many drivers were removed to create this smaller iso.
Minimum requirements to run the OS:
Processor: 400MHz.
RAM: 256MB.
Hard drive: 1GB.
Video card: any built into the motherboard or processor.
Once installed on a hard disk, the operating system takes up 785MB of disk space, a very small footprint. When disk space is compressed for saving space, it will only take up 555MB of disk space. Installation time on a regular PC takes only several minutes or seconds.
Introducing a super-lightweight build of Windows 7 designed to run on ancient netbooks and computers from the last decade of the Windows XP era.

Thanks it works on my friend’s computer but not on my computer, why?

I followed these steps on Mac using Hex Fiend and DAEMON Tools, and I burned the iso using Bootcamp. When I tried to install on an IBM R51, Thinkpad, it didn’t work. It said 512mb ram not installed. I was using 256mb. Can you please tell me how to fix the error or send me a pre modified iso to my email?

I could not find the string you mentioned in windsetup.dll in Windows 7 Ultimate 32 bit, what to do? Please guide me

I tried it and it did not work, wasted a DVD 
I had to download the RTM release to find the string specified, the newer versions don’t have it, but it still didn’t work
By the way, to edit the ISO don’t use the suggested programs, they charge money. Download a program called Anyburn, the hex editor used in pictures is the one you want
But like I said, it still didn’t work If anyone figures out how to make it work email me morejiggawatts at gmail com

Not always cheap — — or simple
I have an old computer that I am running Windows 2000 on that doesn’t run it too well with 256 memory. It uses PC133 memory, but according to Memory Giant, the maximum memory for this particular motherboard is two 128 memory sticks (two slots). Memory price is not the issue here. I haven’t used this computer for some time now. Maybe I will attempt to install W7 just for kicks and report back here. Windows 7 on a Celeron processor and 256 MB memory?????? Well, at least the original 10 GB harddrive has been upgraded with an 80 GB.
To increase memory, I would have to replace motherboard, processor, processor fan, memory, power supply (120 Watt), and case because an adequate power supply would not fit this case, couple of case fans, and then my recently installed second hand 80 GB harddrive would want to be replaced with at least twice that. At least I could salvage my 3.5 floppy drive and the recently upgraded DVD-RW — but the beige would not match the gray or black case that I would have to buy…………… NAH, I don’t want a memory upgrade on that box.

Not this time
I attempted to install Windows 7 build 7260 on a 12 to 15 year old computer with a Celeron processor and 256 MB ram. This computer has been upgraded to an 80 GB harddrive (from a 10 MB) and a recently installed DVD-RW drive. The computer proved unable to even read the Windows 7 install DVD. (this same disc worked on another computer, so it is known to be a good DVD). I just placed the DVD in the drive and rebooted and even with a functioning Windows 2000 installation, the computer would not even recognize the DVD. (Would not get past the «Boot from CD/DVD prompt». Pressing the «anykey» proved fruitless.) The DVD drive does function normally with other DVDs. After about three tries I gave up. That’s MY experience at attempting to install Windows 7 on below spec. equipment. Others may have a more satisfactory experience, but that’s mine.
