If you want to share files, you don't have a mobile device in your hand, and the network transmission is too slow. At this time, you can try LAN sharing transmission. LAN sharing requires both parties to be in the same LAN environment. So, how to set up LAN sharing?
1. Open "Network and Sharing Center" and select "Change advanced sharing settings".
2. Check "Enable network discovery" and "Enable file and printer sharing", and then save the changes.
3. Then we open the "Computer" right-click menu and select "Manage".
4. In "Computer Management", we click: Local Users and Groups - User - Guest, double-click Guest.
5. In "Guest Properties", uncheck "Account Disabled", and then OK.
6. Then we open the start menu, enter secpol.msc and press Enter.
7. After opening the "Local Installation Policy", we click: Local Policy - User Rights Assignment - Deny access to this computer from the network, and double-click "Deny access to this computer from the network".
8. Then in "Deny access to this computer from the network properties", select "Guest", delete it, and then confirm.
9. Then we click: Local Policy - Security Options - Network Access: Sharing and Security Model for Local Accounts, and double-click "Network Access: Sharing and Security Model for Local Accounts".
10. In "Network Access: Sharing and Security Model Properties of Local Accounts", select "Guest Only - Authenticate local users as guests", and confirm to exit.
11. Then, find the file or folder that we need to share on the local area network, open the right-click menu and select: Sharing - specific user.
12. Then select "Guest" from the drop-down list, and then click "Share".
13. Here, the Win7 LAN sharing settings are completed.
If you feel that the above settings are troublesome, you can also use local area network sharing software, such as local area network messenger, etc.
