Introduction for Registry Keys

The Windows Registry is a hierarchical database that stores configuration settings and options on Microsoft Windows operating systems.

It contains settings for low-level operating system components as well as the applications running on the platform. The kernel, device drivers, services, SAM, user interface and third party applications all make use of the registry. The registry also provides a means to access counters for profiling system performance.

In Here I will be explaining how to edit the registry, view the Changing Keys And Values in Registry Editor (Regedit.exe).

Note that you should make a backup copy of the registry files (System.dat and User.dat) before you edit the registry.

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall Windows 95.

While I was installing "VPN Client install" I I got windows "Error 27850".

this error is caused by default value set by Windows 7 in the registry key at

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network\MaxNumFilters

By default, this value is set to 8 and apparently can be set to a maximum value of 14.

How to make it?

1. Click on the Start button.

2. In the search box, type 'regedit' and then press Enter. The Registry Editor program will open.

3. Using the > icon, navigate through the registry key branches until you reach the Sub Directory

at " HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network\"

4. Right Click on "MaxNumFilters" go to Modify

5. Add 14 by removing 8 and click on OK

Then you will see it like this

6. Reboot.

Work Done!!
