Introduction

After a number of hints in my direction on when regcheck will support the newer OS's from Microsoft that have implemented SMB2 (think about Vista / Windows 7 / Windows Server 2008 (R2) / Windows Server 2012 ) it might just be time for implementing this part.

background

Please be aware that you need to switch off opportunistic locking -oplocks- when using the embedded database for reliable sharing of database access when multiple users are accessing the database simultaneously.
The recommended solution for this is to use an SQL database, but sometimes that simply is not an option.
This is where regcheck comes in and assists the developer in that:

a) the oplock settings are set correctly
b) the settings stay correct when using the application by verifying the settings on each start of your application.
c) workstations and servers are both set.

Complications

There are a number of new reasons on why Regcheck was never updated to support the new (/) operating systems.

1. We didn't have an urgent need for this ourselves.
2. The recommended ways for reliably detecting the operating system have changed.
3. Microsoft has implemented a new SMB protocol with new oplock settings (SMB2)
4. The changes that are required are very poorly documented by Microsoft.
5. In order to make the required changes on Vista+ the user needs to have sufficient user credentials. Having the user disable User Account Control (UAC) for committing the required registry changes was not an option. This means that the actual change has to be moved to an external application.
6. As opportunistic locking settings depend on a negotiation between the server and client OS, there is a vast array of combinations in operating systems that needs to be supported.
