I’m reposting this from a thread buried in a forum that solved my problem with Steam being unable to launch in case the forum goes link dead.
The error from Steam is:
Running Steam in Windows compatibility mode is not recommended. Please remove any Windows compatibility settings for all users under file properties for Steam.exe and restart Steam. Press 'Cancel' to permanently ignore this warning and continue.
This has happened to me personally twice. I believe the most recent is due to having a game running (downloading the Rift client) and then the machine reboots (due to a Windows Update at 3 AM) and Windows thinks its doing you a favor by marking the program that it needs to be run in compatibility mode since the app either won’t respond to a shutdown request or doesn’t shutdown properly.
Here’s the fix:
- Hit start->run->regedit
- Go to key: HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers
- Look for a entry with your path to steam.exe
- Delete that entry
- If you don't find it there try HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers
