Hi,
Try cellulose thinners,it can be picked up in your local hardware store and it wont damage the windows so long as they are not self cleaning,apply it to a dry cloth and wipe over the masking tape residue repeatedly until it dissappears,clean of with damp cloth and soapy water.
hope this helps
Try furniture polish! Yep, I know it sounds crazy but it works! It's a simple remedy and will probably cost you nothing as most people have it! Spray it on liberally, leave it a while and then clean it off with a duster.
I discovered this trick when I was getting frustrated with trying to remove sticky labels from a guitar we bought 2nd hand for our daughter. After searching the internet we discovered that furniture polish was the answer. I was amazed to find out that it actually worked! All I used was the cheapo shops own brand. Since then I have used it on glass jars to remove labels etc and it has worked every time. Good luck!
