Let me fix it myselfTo resolve this problem, adjust the value of the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network\ registry subkey. To do this, follow these steps:
1. Click Start , click Run , type regedit , and then click OK .
2. Locate and then click the following registry subkey:
3. In the right pane, right-click MaxNumFilters, and then click Modify.
4. Change the value to “14”, and click to select the Decimal option, and then click OK.
Note: Default value is 8, 14 is the maximum
5. Close the Registry Editor.
If more than 14 filter drivers are installed on your computer, the above registry key will not alleviate the issue. If you have more than 14 network filter drivers installed, remove a number of the installed filter drivers to allow the service pack installation to succeed. Network filter drivers can be removed from the properties of the network connection in Ncpa.cpl.
Note: Do not remove the default Microsoft network filter drivers, such as Client for Microsoft Networks, QoS Packet Scheduler, File and Printer Sharing for Microsoft Networks or any of the included Internet Protocol entries. Examples of third-party network filter drivers would be firewall, QoS software or network virtualization software.
