Due to a bug in the installer, uninstalling System Shock 2 will wipe user-specific compatibility settings for all applications on your system.
In addition, if you're running 32-bit Windows, system-wide compatibility settings will be wiped as well.
Affected registry keys:
All versions:
HKCU\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers
x86 only:
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers
x64 only:
HKLM\SOFTWARE\Microsoft\Wow6432Node\Windows NT\CurrentVersion\AppCompatFlags\Layers (unused key, deleting it is harmless)
