Solution:Windows Asks For Password On Shared Folders On The Network

I have found a way to disable the nagging password box in Windows 7 (probably Vista too).
1. Click Start
2. Under you user picture, right click Network
3. Choose Properties (this opens Control Panel\Network and Internet\Network and Sharing Center)
4. Click Choose homegroup and sharing options in the lower list (this opens Control Panel\Network and Internet\Network and Sharing Center\Homegroup)
5. Click Change advanced sharing settings… (this opens Control Panel\Network and Internet\Network and Sharing Center\Advanced sharing settings)
6. The setting right before the last one is: Password protected sharing!
7. Choose Turn off password protected sharing and you are good to go without any restarts and stuff.
