Using IObit Driver Booster for more than 5 years. Quit depandable and useful application. No problems at all if it is used properly with common sense. With time new versions not only improved in features and larger database but also faster in speed. Highly recommended for updating and keeping a backup of drivers at best. If added the boot restore function this program would become certainly a industry leader in its category. Please consider it for future versions as millions of fans would be added to IObit portfolio. Thanks IObit and sharewareonsale for this this offer, its great. Thanks Ashraf, keep up the good work.
