Issues with the Windows client's information and status window

Hi all,
I am looking for a little bit of help. I am in a school running about 10 displays via the 1.7.9 CMS on a windows server and the 1.7.9-win32-x86 windows client on Nooks with the following specs:
Processor: Intel core i3-3217U CPU @ 1.8GHz
Ram: 4GB
OS: Win 7 64 bit
My issue is that when I go to look at some of the machines download process (which can be very slow but im not sure if that is our network or not.) the client info and status window looks like this
If there is anything I can do could you please let me know.

Could you please open php.ini

make sure it’s set to -1 and that it’s not commented out (no ; before that line in php.ini)

Restart your web server

Cheers for your swift reply.
