This build utilizes a valid SHA-1 production-signing certificate (signed by the Microsoft Windows Verification PCA certificate chain, associated with Windows Hardware Quality Labs (WHQL)) and can be booted and installed on the current date. | '''Windows 8 build 7850''' is the official Milestone 1 build of [[Windows 8]], which was originally uploaded to [[BetaArchive]] as an x86 Enterprise SKU version on 12 April 2011,<ref>https://www.betaarchive.com/forum/viewtopic.php?f=2&t=17784&p=207081</ref> then on 17 January 2015, an x64 version of this build was uploaded to the aforementioned website along with additional SKUs for both the x86 and x64 architectures and its [[Windows Server 2012 Build 7850.0.winmain_win8m1.100922-1508|server counterpart]].<ref>https://www.betaarchive.com/forum/viewtopic.php?f=2&t=33441</ref> A screenshot of the Simplified Chinese language pack for this build was uploaded onto the Chinese forum Baidu Tieba on 12 June 2020.<ref>ziyiyu123. [https://web.archive.org/web/20221105104350/https://tieba.baidu.com/p/6743796365 谁有win8 7850测试版的中文包？有一个1G运行内存的W], ''Baidu Tieba''. 12 June 2020.</ref> Being very early in development, many areas still include the [[Windows 7]] branding and the operating system still uses the version number of 6.1. Files from the ARM32 compile of this build were discovered on the Microsoft Symbol Server on 24 May 2022. | ||

shell32.dll has code to print the hash ID in the about box and desktop watermark, which appears to fail in this build (hash ID is only printed if the function to obtain it succeeded). The public symbols for this build give a mangled name for this function as bool GetEulaHash(wchar_t*, size_t), although compiler or link-time optimizations removed and inlined the second argument (length of output string buffer in characters). The function retrieves the default value in the registry key HKLM\SYSTEM\WPA\478C035F-04BC-48C7-B324-2462D786DAD7-5P-9. This value must be REG_BINARY of size 128 bytes; this data is split into eight 16-byte buffers, Hash[n] is equal to the nth byte of each of the buffers XORed together. | <code>shell32.dll</code> has code to print the hash ID in the about box and desktop watermark, which appears to fail in this build (hash ID is only printed if the function to obtain it succeeded).

This build re-introduces support for 32-bit UEFI boot, which was absent since [[Windows Vista]] post-reset development. | |||
Also integrated support for booting from an exFAT partition, along with 4K Native logical sector and Hybrid boot. | |||
