wvxwxvw No, installed fullver doesn't work on win7 x64 anyway.
But
bbearren's trick seems work.

For those who do use a pagefile, there is a fairly simple means of preventing pagefile fragmentation. First, in "System Properties" "Advanced" tab, click on the "Settings" button under the "Performance" header. Click on the "Advanced" tab in "Performance Options". Under the "Virtual memory" header, click the "Change" button.
In the virtual memory dialog box, highlight each of your listed drive letters, click the "No paging file" radio button, and click the "Set" button. After all listed drives have been set for no paging file, OK your way back out. Windows will advise a reboot before the settings take effect. OK and reboot.
Next, defrag the drive where you want your paging file. Having no pagefile will not be a handicap for this procedure. When the defrag is finished, go back through the above steps, except now highlight the drive of choice, click the "Custom size" radio button. In the "Initial size (MB)" and "Maximum size (MB)" fields, use the same value. I suggest 4096 (4GB). OK your way back out, and again Windows will advise a reboot. OK and reboot.
Having defragged your drive of choice, and making the pagefile 4GB, it will be written as a single contiguous file on the drive. Having set the custom initial size and maximum size to be the same, Windows will never try to resize the pagefile, and it will stay in its contiguous state henceforth.
This is the procedure I used back when I still used a pagefile, and it worked very well indeed. The pagefile never fragmented.[/more]
