Windows EC2 instances load too slow

Testing customizations to the default windows 64bit image ( ami-976edafe ) shows that it is taking about 5 minutes for the agent to boot up; plus the time to boot up the instance makes loading Windows agents to take 8-10 minutes.

A linux agent is generally available in ~1min. Please improve the loading process for Windows instances.

By the way, trying to fasten the process by using this script (c:\opt\bamboo-elastic-agent\bin\prepareInstanceForSaving.bat), as it is described here, doesn't make any difference.
