Starting with Vista, manufacturers started making much or all of their profit margin on sponsor's bloatware, so gradually they have started enforcing it. Gateway and Dell stopped always providing a clean copy OS DVD + drivers/apps CD, forcing users to buy/make Recovery disks which will only install with bloatware. Some tech support won't even support clean reinstalls and require factory condition restore to service hardware warranty.
The solution to this is to find a clean copy of the 7600 RTM and unlock all versions http://www.windowsvalley.com/blog/un...e-x86-and-x64/
By leaving the key blank during install and unchecking box it will auto-activate afterwards using the key embedded in the mobo whose batch key is stickered on your computer. If a robocall to MS is required it will sort out the specific key (available by running Belarc Advisor) from the batch key and activate every time. You own that version license for that computer, period.
Now you need to find the apps you still want from the manufacturer's Support download page for your model. The Windows 7 installer is already driver-complete for the most part, followed up by WIndows Updates. Then get Adobe Reader/flash and Java runtime and maybe free Ofc. from their websites.
