Hi, I am deploying Win 7 operating system, customized with Drivers and Softwares, The installation is going fine, the size of the Image is close to 15GB and i am using a 32 GB USB pendrive for installation. Everytime i have to modify anything on the Task sequence i will have to recreate the image and again copy it from the servers in DC, this takes almost a day. Is there any way i can edit the Task sequence within the Media created earlier so that it can save a lot of time. Thanks for response.
