A lot of HTC phone green-hands have the same trouble, that is: they know backup their phone data is necessary, However, they didn't get the easy way to  transfer the data to computer, like contacts, text message, music or other,  so that waste a lot of time.
In fact, there is a very simple way to transfer contacts, SMS, photos, music, videos from phone like HTC to windows computer. To finish this task, I recommend a HTC Contact Transfer called Vibosoft Android Mobile Manager. With it you can get the transfer job done in just three steps.

How to copy htc contact to computer ?
Step 1  Connect HTC to Computer and Run transfer software
This program will detect your HTC phone immediately. Then your HTC phone shows up in the primary window. At this time, you need to enable USB debugging.

Step 2  Choose the contact which you want to backup
After finishing installing USB driver, this program will automatically scan your phone data, and soon you will get a menu as shown. You can see all the catalogs on the screen, like contact, SMS, Music etc. Press the "Contact" button, all the contact on your htc phone will be shown, choose all or some contact that you want to transfer.
