bad buy purchase driver update $49.00. after filling form my credit card info slim driver pop up.I don't want anything else but one yr. driver update.they never gave me any comfirmation number or chance to use the special coupon @19.95 so please cancel everything but driver update for one year and its not working right right now

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.

Slim Drivers is very slim Beware Be careful they will try to get you to purchase Tech Support by running you around took THREE HOURS TO DOWNLOAD This company's offer of $29.95 turns into $49.95 as you start to order they fill two more charges no way to decline the program slowed my computer down to a crawl that's when another agent tell you that need add tect support this will never be post on there reviews that's how you can tell they are on the shady side they use three different companies I'M SORRY I FELL FOR THERE COME ON AD BLEW $49.95 FOR A VERY SORRY PROGRAM BEWARE

4 1/2 stars It does exactly what it says it will, but I suggest doing it before you load your computer with other software/hardware. I advise getting SlimDriver, after you get your new PC or when you recover from a computer crash and are forced to wipe your system clean, as was my case. Unfortunately SlimDriver could not find updates for all my drivers. So be prepared, it does it's job but some things the user still has to know how to do on your own.
