Made My System Stable I've used it on my Acer desktop which had become very unstable. I was seriously thinking a clean install. No other amount of cleaning and repairing helped. I came across a number of articles about updating drivers to fix problems, something I hardly ever do. So i saw this program mentioned in a newsletter (sorry can't remember which one). Decide to give it a try (SlimDrivers). So far no regrets. If you don't want the cleaner instaalled as well just pay attention to the install screens. Accept the first license don't accept the second)

Drivers updated some many years old. First go this seemed to work through a replacement of an assembly of old drivers carefully and without issue after many separate reboots. I certainly have gained confidence in this program to look after me. I am not schooled in this stuff but I note midway through the update speed was enhanced, particularly printing. Yet to experiment to fully test other probable changes.

Fantastic I took fear when I updated drivers in 2 laptops with the tool iobit updating drivers, and had to restore one with a point of restoration and other one with initial instalación of factory. The laptops are Compaq presario cq60, HP Pavilion dv7 and Asus Eee PC 1005PXD. Many thanks
