In earlier version of Windows NT, both DaylightName and StandardName values contained the actual strings relating to those items. In later versions, these values were changed to reference a string of text stored within a string table embedded within a DLL (see Figure 1).
For Windows 7, the string table is contained within a dynamic link library called ‘tzres.dll’. If this file is opened in a resource viewer, we can examine the string table values. Figure 2 shows a small part of the string table when viewed from Microsoft Visual Studio. In Figure 1, DaylightName is stored as string 1501, with StandardName stored as string 1502. The corresponding values in the string table show ‘Turkey Daylight Time’ and ‘Turkey Standard Time’ (see Turkey Standard Time Sub-Key).
