iSeePassword Windows Password Recovery is one of the best among them.
Password recovery technology has made a huge breakthrough in recent two years due to the high demands of end users. The truth is that you can reset Windows password of any Acer computer without losing a single piece of information unless it was powered by Windows. Two of them tried to reinstall the OS but all the precious data on system disk were removed permanently. One problem that they came across often is how to recover the admin password of their laptop when password was forgotten. Some of my friends and family members use Acer laptop as their main working machine.
Acer is one of the most renowned manufactures for laptops.
