Hello thx, this are new info for me, I will study them and give feedback, thx again.

Hi, we have 10 types of laptops (win7) + 10 types of desktops (xpsp3). I look for tool (process) how can I comfortly update each image. For example: Last month we buy new AV client ( I need reinstall antivirus client on all 20 images).
Now I must call 20 people (each with different HW - different FOG image) to deploy image - make changes on image and upload updated image again to FOG server. So I look for some tool or app to make me work easier.
