Yes, you can start a new thread here in the Microsoft Operating Systems forum here and people will help you.
You should post what kind of help with security you need. As for file sharing, you can read something like this:
http://www.addictivetips.com/window...haring-share-users-system-folders-on-network/
Or if you want us to help you step by step, we can do that too:
Right click on Folder you want to share > Properties > Sharing TAB > Share... >
From drop down Menu select: Everyone >
Add > Everyone > [Next to Everyone] > Read/Write > Share > Done > Close
Control Panel > Network and Sharing Center > Change advanced sharing settings > [scroll down] All Networks [scroll down] >
SELECT: Turn off password protected sharing > Save changes
If asked for a Network password even though one was not setup,
Control Panel > Network and Sharing Center > Change advanced sharing settings > All Networks > Turn off password protected sharing > Save changes > Reboot
The fist part of your post unclear:
"the second time I open it id does not work" What does not work? When you say "disperses your desktop icons" - right click on Desktop > Sort by.
If you want to save Desktop icon placement, use this program:
