windows8appstore.com = Where you download Apps for Windows 8?
Filehippo.com
Majorgeeks.com
Download.cnet.com
Softpedia.com
Softonic.com
The software official sites
or Others (write it down in your reply)

Sorry the first option should be windows8appstore.com. I can't edit it anymore now.

Most time, I download software from their official sites. Then are windows8appstore.com, Filehippo.com, Majorgeeks.com, and Download.cnet.com.
