As we cannot reproduce this problem on our XP/Vista systems, here are some tips:
1) Just click on desktop icon of UltraISO, normal speed as expected?
2) If the answer is YES, choose 'Options'->'Configuration' from main menu, swicth to 'Integration' page, uncheck 'Integrate UltraISO into shell', click 'OK' and try again
1. by clicking on ultraiso icon, the program loads fast into the taskbar but the interface shows up after about 6 seconds.
Perhaps the 1st boot after the installation is instant.
2. not applied since the answer is NO.
