Hello again, Sorry didnt't have time to write a documentation. so when you run the executable file: 1. it will extract its contens ( which are a batch script, wihu.exe and other usefull batch commands) to the temp directory. you can extract the contens anywhere with WinRAR or so and see the complete source 2. It will begin downloading all category folders (eg. 0_System, 1_ Graphics,..) found in the "installers" folder on the server and all batch files (with extensions cmd) within these categories. so it is NOT installing anything yet !! This is the way how i kept it easy to update, just by uploading the new application batch file for in the right category folder 3. Now the program will begin to check if these programs are installed already on your computer. for example if "Firefox.cmd" has been downloded, then TGUP checks if "Firefox" is installed on your System. if it is not installed then it will be set to selected=1 for WIHU. The "installer.ini" of WIHU is now completely built. 4. Now WIHU starts with an autoinstall counter (30 sec.) you still have the option to select or deselect manually the applications. as soon as u interact with changing selections the counter stops. otherwise it will begin running the applications batches one by one. 5. The Application batches are set to download the program from the server and install it silently to a Submenu named as the category in the startmenu folder. for example "Firefox" will be found under the Submenu "Internet" in the Startmenu. PS: CleanUp is not a program, it will just empty yout temp again after the installation is finished.
