********DISCLAIMER******** This is not pirated, pre-activated, or patched in any way!!!! you still need your windows home premium Key to activate the software. I made a lite version of Windows 7 Home premium x86 to install on our Viewpads, it is around 6Gb installed (4GB after applying the tips below), I took out a lot of useless crap but still left the necessary drivers and software for it to function correctly including windows updates. before you begin, I recommend downloading the drivers or copying them from the cd to an sd card, or you can get a driver backup program, here are some good free choices. Option #1: you can write it to your thumb drive using your favorite ISO writing software. Option #2 format your thumb drive to NTFS, copy all the files from inside the ISO onto the thumb drive, open the boot folder, hold shift and right click somewhere in the empty space and select open command window here, then type this, bootsect /nt60 drive letter: and hit enter, say your thumb drive letter is L then this is what it looks like (without quotes) "bootsect /nt60 L:" it will probably say it may not have worked because access denied, just ignore it, close the window and boot from the usb. if it doesnt let you boot from the usb something about boot MBR missing, change your user account control setting to never notify me, reboot and type the command again. you can input your cd key during or after the install, the benefit for doing it after is you have 30 days to activate it and you won't have a black screen popping up telling you that you need to activate windows now. if automatic activation fails, (it is a little touchy in the activation area because of the programs removed) just do the phone activation and it will be fine. Again, this is in no way to be used for pirating, cracking, or patching, it is just the windows that came with the device and you still need a cd key to get any use out of it. Download Windows 7 home Prem TIPS to reclaim even more space turn off hibernate (google on how to do it) it saves almost 1Gb, turn off or clear all but the most recent restore points by going to computer> right click C: drive and select properties> select disk cleanup> select more options> you will see the option, (space saved varies) turn off or reduce paging size, go to start> right click computer and select properties> on the right hand side select advanced system settings> go to advance tab and under performance select settings>advanced>under virtual memory select change, now here you can either turn it off completely (recommended if you upgraded to 2Gb of RAM) or reduce the total size, if you still have only 1Gb of RAM I recommend reducing it to 1Gb then restart the tablet, the computer will only use the space that is allocated here if you are trying to install or open a program that is bigger than the amount of RAM your computer has, i have it turned off and haven't had one problem so far.
