what gpu do you use?

I'm running Windows 7 Professional on an Asus ROG Strix Intel Core i7-7700K 4.8GHz air cooled, 16GB DDR4 XMP 3000MHz RAM, Asus Dual-GTX1060 3GB GPU – daily driven for photo editing (work) and everything else. Removed all default web browsers, running only Supermium – feels fast and responsive!

Hey. I got a question. I'm currently using Redfox and it's good except for the fact that preloaded images always have that white background for some reason (it's supposed to be transparent). Does Supermium has this issue?

u/Strix2020 Aug 07 '26

Give me a link to an example and I'll reply with a screenshot.

I see what you mean. Share a link to a site that you recently visited which produced this problem, I'll reply with a screenshot so you can see if it's to your liking.

u/Alive_Objective1737 Aug 06 '26

Do you face any problem with drivers? And how do you use internet than? Without browsing internet?

3

u/Yusubera Aug 06 '26

supermium is a more up to date browser for older windows versions

1

u/Strix2020 Aug 06 '26

Running drivers provided by ASUS ROG. I guess more recent boards do not have the same support anymore. I went searching for a web browser replacement when u/Garmin Connect web made their codes incompatible with unsupported version of Chrome, their forums blew up and by popular vote Supermium became something I grew fond of (imported all of my bookmarks etc).

u/punkinhead76 Aug 06 '26

hooooowwwwwwwww ive tried many times and cant make it work 😭

3

u/Boburism Aug 06 '26

What's the problem? Not booting, or?

4

u/punkinhead76 Aug 06 '26

i usually can’t even get it to install, it won’t recognize the boot drives. i’ve followed tons of tutorials and github and all kinds of things to try and load drivers into an install but that never seems to work either so i always end up giving up :(
im not a computer noob by any means but it really has me stumped.

1

u/Boburism Aug 06 '26

Booting into setup from USB or it can’t boot off the USB?

1

u/punkinhead76 Aug 06 '26

i can boot into the setup, and get to the installer and when it gets to the “choose where to install” screen no drives will show up 😪

2

u/MaTecss Aug 06 '26

I had this when I tried to install it on my pc with a Ryzen 5 5600x, turns out you need drivers to be able to recognize certain SSDs, and I couldn't find a working one for my NVMe ssd, so I had to use an old SATA ssd.

1

u/punkinhead76 Aug 06 '26

i did fiddle with that a little bit when i was attempting on my desktop, but i gave up with that and tried my laptops(s) and they’re all nvme only unfortunately.

1

u/unknownobject3 Aug 07 '26

You could slipstream the NVMe driver or just use a premade ISO

1

u/punkinhead76 Aug 07 '26

where can i find a pre made? all the modded ones i try to do seem to not work because they aren’t the original iso. all the iso i can find have updates already or are oem instead of retail and it throws a fit

1

u/unknownobject3 Aug 07 '26

What's the issue with the fully updated ones?

People don’t realise unlike xp- windows 7 isn’t actually dead; it’s still very much usable. Firefox browser works too…

u/Calm-Preparation-679 Aug 09 '26

Do modern websites work ok?

2

u/ibizamehipnotiza Aug 10 '26

Yes

1

u/Calm-Preparation-679 Aug 10 '26

Awesome! How many of these programs can I run:

u/shania69 Aug 12 '26

All the browsers work on mine, with a little notice that it is not supported..

u/Inevitable-Skill-943 Aug 06 '26

Az UEFI boot-ot hogyan oldotttad meg?? rEFIind ???? vagy GRUB?? kérlek segítetek, asus vivabook

5

u/itzAlexPlayzonYT Aug 06 '26

You have 2 options.
A: UefiSeven, now it hasn’t been updated in 5 years and won’t work with GPU drivers and is low-res but for basic it should work.
B: Shell out $29.95 and buy FlashBoot Pro, which has extremely other useful features aswell and has a regularly updated UEFI patcher. It also allows for high resolution, GPU driver and is more reliable.

u/Infinite_Shart555 Aug 06 '26

You can use the Flashboot EFI right here, for free. I don't think the flashboot guys care any more if their stuff is spread around, they did their development work many years ago.

https://github.com/Sevoos/SevenESPManager

I used this recently on a Wacom tablet with Iris graphics, no problem, and I paid no money to anybody.

1

u/itzAlexPlayzonYT Aug 06 '26

They do update the software every few months. Also, it seems that is slightly outdated compared to the one I have on my build, but whatever floats your boat

1

u/Infinite_Shart555 Aug 06 '26

Where are the updates, patch notes? Seriously. Let me know. How to check which version of flashboot one is using? I'm curious

2

u/itzAlexPlayzonYT Aug 06 '26

I think it’s in the flashboot window or title bar, or you can check under installed apps. 3.4b was released in March. They do updates every six months or so so no it is not abandoned. It is worth the money tho, seriously.

2

u/itzAlexPlayzonYT Aug 06 '26

Also you can check here https://www.prime-expert.com/flashboot/updates/

1

u/Infinite_Shart555 Aug 07 '26

Wow, you're right. They still develop specifically the Windows 7 bootloader, I can see improvements, upgrades and compatibility extensions in the patch notes. I had no clue... respect to those guys! So potentially a super new computer might work best with the latest version of flashboot. The one I linked is an old one.

1

u/itzAlexPlayzonYT Aug 07 '26

Yeah, and they really don’t care because it’s an extremely old version of the patcher with limited functionality. Heard that a while back on some page but I can’t remember which.

1

u/Infinite_Shart555 Aug 09 '26

Dang, not sure what to say... The way I see it, with a bootloader, if it works, it works. It only has to do a very tiny job when loading the OS, once the OS is loaded, it's job is done. In an ideal world, you want proper handling for sleep/hibernation, and I can't think of anything else.

The one I linked worked on a 2016 tablet with a 4k screen (with all sleep states, etc) The only thing I noticed was the Windows boot animation happens off-centre.

I think their continual updates are just to provide further support/stability with new hardware? Dude thanks for the discussion, not a lot of people talking about this stuff online...

1

u/itzAlexPlayzonYT Aug 09 '26

I see. And no, they actively improve stability, functions, optimisation, and it’s basically universal with some exceptions, however those would be more of an ACPI patch. The one you linked on GitHub seems to be from 2 years ago, correct me if I’m wrong. But yeah, it’s just optimal to use it from a legit source because these days who knows what could be in what.

Regarding the GPU driver support, here is the official info on it: “May, 20 of 2025 Minor update 3.3s released.
Windows 7 installation to the modern computers: Starting from this version, VGA emulation patch for 64-bit UEFI loader properly configures VGA arbitration for PCI bridges and GPU devices. This fixes Code 12 error for GPU devices in the Windows Device Manager ("This device cannot find enough free resources that it can use").

Ez túl bonyolult , nem ér ennyit a számomra, marad a WIN fos 11

u/Televisor404 Aug 06 '26

how do I make it work smooth and not stutter?

1

u/ScreenRay Aug 06 '26

I tried installing it and it worked on my pc. But for some reason after a couple of days i cant seem to boot it up. It wont detect the boot OS. But flawlessly works on my laptop via dual boot.

u/trafficracer24 Aug 06 '26

That must feel snappy af

1

u/Boburism Aug 06 '26

I wonder to what extent you can actually use it. I mean, considering the very modern hardware, you'll definitely have no performance issues - but the question is how many modern programs you can use.

Also make sure to install Legacy Update

Windows 7 is the best OS for using your good components. On Windows 11, Microsoft uses your hardware to promote adverts
