The specified network provider name is invalid

My internet connection is working, everything is OK, but...
I cannot share any folder on my PC. I haven't used sharing several months now, It was working perfect back then.

The problem:


Some screens of current network settings:

C:\Users\andre>ipconfig /all

Fixes tried to apply:

Run the built-in Troubleshooter

NIC driver uninstall, update

Kapersky Internet Security uninstall

Windows firewall turned off

Reinstalled in adapter properties

• Client for Microsoft Networks
• File and Printer Sharing for Microsoft Networks

sfc /scannow

• netsh winsock reset
• netsh int ip reset
• netsh int ipv4 reset
• netsh int ipv6 reset
• ipconfig /release
• ipconfig /flushdns
• ipconfig /renew
• ipconfig /registerdns

Winsock keys fix

Code:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock2

The services that need to be turned on are listed below:

• DNS Client
• Function Discovery Provider Host
• Function Discovery Resource Publication
• Peer Networking Grouping
• HomeGroup Provider
• HomeGroup Listener
• SSDP Discovery
• UPnP Device Host

1. Open your Registry Editor (Start -> Run -> regedit.exe)
2. Navigate to Computer:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\NetworkProvider\HwOrder
3. Backup the string ProviderOrder (copy what you have into Notepad or something)
4. Alter the string ProviderOrder to "RDPNP,LanmanWorkstation,webclient"

No luck
