UltraVNC v1.0.2


UltraVNC v1.0.2 is a program developed by UltraVNC. Upon installation and setup, it defines an auto-start registry entry which makes this program run on each Windows boot for all user logins. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The software is designed to connect to the Internet and adds a Windows Firewall exception in order to do so without being interfered with. The software installer includes 29 files and is usually about 3.68 MB (3,857,971 bytes). In comparison to the total number of users, most PCs are running the OS Windows XP as well as Windows 7 (SP1). While about 38% of users of UltraVNC come from the United States, it is also popular in Italy and Germany.
