This will mean that you theoretically get access to run Steam API v21 games
This will only work with the Extended Kernel installed, so keep that in mind
Step 1: Download the Steam client from https://mega.nz/folder/GRlSCZwY#0qCL7SJkYllwkSr8RAZMYg/file/TIknQQSJ
Step 2: Download steam.cfg and ntk32.dll from the attachments of this post
Step 3: Extract the client files
Step 4: Copy steam.cfg and ntk32.dll to the Steam folder
Step 5: Go into C:\Program Files (x86)\Common Files\Steam and copy ntk32.dll to there as well
Step 6: Open sdl3.dll with CFF Explorer, go to Import Table, kernel32.dll and change SetWaitableTimerEx to SetWaitableTimer
Step 7: Spoof the Steam client and Steam Web Helper to think they're on Windows 7 with osver.ini
Step 8: Replace bin\gldriverquery.exe with rundll32.exe or another EXE that does absolutely nothing to prevent a crash message on startup
Step 9: Start Steam with the following parameters: -cef-disable-sandbox
Step 10: Log in as usual
Some things i've noticed
Games may still crash, each game will have different fix steps that are out of scope for this guide
The Store, Workshop, etc will not load. The Library page works fine.
It does not work well without DWM.
