ACTIVATION WINDOWS 7 ULTIMATE ON DELL LATITUDE D820 CAN BE DONE I came here to find out how to INSTALL WINDOWS ULTIMATE 32 BIT for my 3 YEARS OLD DELL LATITUDE D820. After so many activation attempts, I FINALLY GOT IT LICENSED AS IT SHOULD BE. ( very proud ) . I decided to write this article for DELL LATITUDE OWNERS out there who wants to upgrade to WINDOWS 7 ULTIMATE but do not want to do much digging around. PREPARATION: DOWNLOAD WINDOWS 7 ULTIMATE RTM BUILD 7600.16385.x86fre.win7_rtm.090713-1255 . This is the lastest and final from MICROSOFT TO THIS DATE. I do not know any other versions will work with this activation process. DOWNLOAD the modified version D820_A09_SLIC of the BIOS. This version will have SLIC 2.1 required for 7LOADER. Dell released SLIC 2.0 version on their web site, this will not allow you to active your WINDOWS 7. This is the file name which I found somewhere in this awesome forum "DELL_Latitude_D820-DELL-A09.rar" Search for it boys. I don't want to go back to get the link DOWNLOAD Windows 7Loader By Orbit30 & Hazar Build 1.4 (Released August 12, 2009). The file name is "7Loader 1.4.exe" I attached the screenshot of the software below. STEPS TO ACTIVATE: YOU need to flash your bios with the program D820_A09_SLIC.EXE. Dell DO NOT ALLOW to flash without BATTERY so go to find your battery and plug it in. After you run the flash program , the laptop will restart automatically. SIT AND WAIT FOR PC TO RESTART. You might see short time of BLACK OUT. THEN You can pop your WIN7 DVD in and happily install your WINDOWS 7 ULTIMATE. SKIP THE SERIAL KEY PART, JUST CARRY ON . YOU DON'T HAVE TO PUT ANYTHING THERE After complete installation. Run "7Loader 1.4.exe" and CLICK ON SLIC 2.1 IN BIOS. WAIT TO SELECT "DELL" CERTIFICATE. THE FIRST DELL. THERE ARE 2 DELL CERTIFICATE IN THERE. THEN CLICK ON "Install 7 Loader" and wait for a few minutes. YOU SHOULD BE ABLE TO SEE YOUR LICENSE KEY POP UP YOU CAN CHECK "ACTIVATION STATUS" AFTER ALL TO SEE YOUR RESULT FINALLY INSTALL YOUR VISTA DRIVERS. XP DRIVERS WON'T WORK ON WIN 7. YOU CAN DOWNLOAD FROM DELL WEBSITE. MOST DRIVERS WE NEED COME WITH WINDOWS 7 EXCEPT GRAPHIC DRIVER. COOL? ENJOY YOUR WINDOWS 7. MICROSOFT , I LIKE YOU SO MUCH. If you need any help, drop me a line.
