Most of you might be using Virtual Private Network (VPN) client on your Windows. There are many VPN clients available in the market and you can choose one as per your requirement. VPN clients helps you to make more secure connection to the Internet and your company’s network. But in case if you’ve never used any VPN client previously and while installing or modifying it for the first time, if you’re receiving error 27850, this post is for you.
Here is the complete error message you may got in this case:
Page Contents
Error 27850. Unable to manage networking component. Operating system corruption may be preventing installation.
You might face this problem for either of these situations:
- Windows limits the number of network filter drivers to default value i.e 8 and the VPN client can’t installed with this restriction.
- You have VPN client installed and you upgraded to Windows 10 from Windows 8.1/8/7 and then you can’t uninstall the VPN client.
Here is how you can fix this problem by increasing network filter drivers to maximum value i.e. 14, in the registry configuration.
FIX : “Error 27850. Unable To Manage Networking Component. Operating System Corruption May Be Preventing Installation.” In Windows 10/8/7
Registry Disclaimer: The further steps will involve registry manipulation. Making mistakes while manipulating registry could affect your system adversely. So be careful while editing registry entries and create a System Restore point first.
1. Press 
+ R and put regedit in Run dialog box to open Registry Editor (if you’re not familiar with Registry Editor, then click here). Click OK.
2. In the Registry Editor window, navigate to following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network
3. In the right pane corresponding to Network registry key, look for the MaxNumFilters registry DWORD (REG_DWORD). It must be having its Data set to default value 8. Double click on the DWORD to modify its Value data:
4. Finally, type 14 as the Value data and then select Base Decimal which should change your typed value to 20. Click OK. Close the Registry Editor and reboot.
After restarting the machine, you can re-try modifying the VPN client configuration and it should work fine this time.
Hope this helps!

This does not resolve the issue
Hi, i was following the steps but in the step 3 i don’t have the MaxNumFilters registry DWORD (REG_DWORD), should i create it?
^^ Yep, you need to create it and set its value as mentioned in step 4.
This did not work for me. Did not find MaxNumFilters, created it and rebooted my computer. I am trying to install Sonicwall. Any other ideas?
This is so frustrating.
@Grace – Did you ever find a solution? I am also trying to install Sonicwall.
Muchas gracias x la ayuda, me es de gran utilidad.
