JSI Tip 7548. How do I enable case sensitive behavior with Windows XP when using Interix 2.2 or Windows Services for Unix 3.0?

To allow Windows XP be use xyz.txt, Xyz.txt, and XYZ.TXT in the same folder when using Interix 2.2 or SFU 3.0:

1. Copy / Paste the following to a ObCaseInsensitve.reg file:

REGEDIT4

[HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession Managerkernel]
"obcaseinsensitive"=dword:00000000

2. Merge the ObCaseInsensitve.reg file with your registry, or run regedit /s ObCaseInsensitve.reg.

3. Shutdown and restart your computer.

NOTE: Normally, SFU 3.0 Setup will allow you to configure this setting.
