Add your code in the section for "U" below. // If you put the code in the section which is NOT "U" then your // code is executed at GUI setup and any changes you make to HKCU // go into the default user (template). Be careful when putting // things here as winlogon.exe (or some other process) may put // your changes into a user profile unconditionally. // 3. HIVEUSD.INX // Checks NT build numbers and does command based on the previous build // number and the current build number only executing the changes between // the builds. If you wish to add something using this method, currently // you have to enlist in the setup project on \\rastaman\ntwin using // "enlist -fgs \\rastaman\ntwin -p setup". To find hiveusd.inx go to // nt\private\setup\inf\win4\inf. Add the build number which the delta // is required and a command to launch %SystemRoot%\System32\shmgrate.exe // with one or two parameters. The first parameter tells what command to // execute. The second parameter is optional. shmgrate.exe then finds // shell32.dll and calls shell32!FirstUserLogon. Code here is for upgrading // HKCU user profiles from one NT build to another NT build. // Code is executed in the process context shmgrate.exe and is executed // at a time where no UI is possible. Always use HKLM\Software\Microsoft // \Windows NT\CurrentVersion\Image File Execution Options\Debugger with // "-d". // Schemes 1 and 2 work on either Win9x or WinNT but have the sometimes // unwanted side effect of ALWAYS getting executed on version upgrades. // Scheme 3 only gets executed on build number deltas. Because schemes 1 // and 2 are always executed, if a user changes (or deletes) that setting // it will always get put back. Not so with scheme 3. // Ideally, the best solution is have an internal shell32 build number // delta scheme which determines the from build and the to build and does // a similar mechanism to what hiveusd.inx and shmgrate.exe do. This // would probably involve either a common installation function (such as // FirstUserLogon()) which is called differently from Win9x and WinNT or // common functions to do the upgrade and two entry points (such as // FirstUserLogonNT() and FirstUserLogonWin9X(). if (bInstall) { NT_PRODUCT_TYPE type = NtProductWinNt; RtlGetNtProductType(&type); // "U" means it's the per user install call BOOL fPerUser = pszCmdLine && (StrCmpIW(pszCmdLine, L"U") == 0); // "SA" means it's ths ServerAdmin install call fServerAdmin = pszCmdLine && (StrCmpIW(pszCmdLine, L"SA") == 0); if (fPerUser) { // NOTE: Code in this segment get run during first login.
