For Windows 10th anniversary this upcoming July, as well as end of support for Windows 10 in its entirety this October. I be going through the initial launch build that has retroactively been called 1507 by Microsoft on my blog.
Above is a image of the Windows 10 1507 desktop upon install. This install has been activated with the Pro edition that wont have the bloatware that is commonly pushed and installed with Windows 10/11 often. The first two feature updates for Windows 10 (1507 and 1511) both have a unique version of the start menu that will have been permanently changed with the following 1607 “Anniversary Update” released the following year.
I ended up first using 1607 when my secondary school upgraded to it back for the 2016/17 school year (grade 12 in my case). I commonly applied this theme back then that would have been lost upon reboot:
When Windows 10 was released, many store pages like on BestBuy used a different wallpaper for the laptop screen’s online. It turns out that it was for Windows 10 beta build 10041 that some how was being used instead of the officially released wallpaper for 1507. It would have looked exactly like this on the laptop store pages screen’s (plus likely some of the Windows 10 bloatware):
Mind you that the build 10041 had a completely different start menu and icon theme pack.
Microsoft Edge was released then as a successor to Internet Explore (ie) but it was built on its own browser engine called EdgeHTML. In 2019 Edge migrated to Google’s Chromium engine and had a brand + UI re brand at the same time. The edge logo/icon had an e to try to trick non-tech savvy users that where still using IE out of habit to use edge with out realizing. EdgeHTML files to render almost any page now even with late 2018/19 builds. Most practcal use is finding mid-2010s sites like cloned ones on the Internet Archive. Or run a basic Web server on your Windows 1507 machine to play downloaded adobe flash games in Edge (it had Flash player support back then).
The “About this PC” did still exist in the Control Panel on Windows 10 before 2021 feature updates removed it. It looked exactly like this in the original 1507 build:
The settings app was very different in the 2015 versions of Win 10 before the 2016 and latter versions:
This is the about PC section in 1507 new settings app:
In 1511 Microsoft added the Windows 10 logo to the top of About PC page. An OEM like NEC or Dell could add there logo instead of the Windows 10 logo. In this case I activated windows 10 with Education edition (a cheaper version of Enterprise given out to Post-Secondary students).
Unfortunately you cant do much in older builds of windows 10, especially this early of a build. Most apps installed can no longer connect to needed servers like the weather app, Microsoft store or news app. Likely due to compatibility issues with these old client apps and Microsoft back end. High chance encryption certificate issues as well.
The best use for such an old build is running Windows XP through to 8.1 software that does not need the internet, possibly late windows 7/8.1 software that needs internet access could also work short term. If your running the Enterprise/Education edition you can disable auto-updates permanently in group policy so you can have it online before system force itself to update to 22H2. The final Windows 10 build and released 7 years latter. Including after major redesigns in 2016 and 2019.
