The VPN, or the Virtual Private Network, is a network that connects multiple users located at different locations using a public network, most often, the Internet. The users of the private network can send and receive information using the Internet, but such data are encrypted in order to ensure their integrity and safety. The Virtual Private Networks are excellent alternative to the leased lines that were used in the past. Namely, telecommunication companies leased lines to companies which were used as private lines in order to exchange information among employees of the same company located at different geographical locations. Having into consideration that leased lines posed enormous financial burden on companies, especially to big companies, the concept of Virtual Private Network was immediately accepted as sure and reliable manner to connect multiple users. There are different types of VPNs, such as remote-access VPN and site-to-site Virtual Private Networks. After we have explained what is VPN, we will go on to explaining you the benefits of using VPNs.

Reliability of a VPN service

When VPN is used in a private network then the network owner can be sure that there will not be any unauthorized users intruding into the network. For this unique feature VPNs are really reliable. VPN uses authenticated links to block any unauthorized access. It uses high levels of encryption to secure your connections. Whatever data travels in your network will be safe and encrypted eliminating all your fears of data leakage. Various tunneling protocols are used to ensure such high levels of security. PPTP and L2TP are such two protocols. L2TP stands for Layer Two Tunneling Protocol while PPTP stands for Point-to-Point Tunneling Protocol. The concept of tunneling protocol originated with the idea to make online data transmission safer and secure.

When Microsoft launched Windows 10, everyone was excited about the new features, including Siri Killer Cortana. But Cortana did not turn out to be what people expected from all this hype. It uses too much CPU power and interferes with the daily activities of the user. Even when you disable Cortana in the configuration, it continues to run “SearchUI.exe” in the background, further reducing the available RAM in the system. And they designed the process so that it never stops and automatically restarts, even when trying to remove it using the Windows Task Manager or Process Explorer.

But there is a way to stop and prevent SearchUI.exe from running on Windows 10. If you do not really need Cortana and the various processes running on your system all the time, you can use this method to disable SearchUI. . .exe also:

Methods to stop searchui.exe

Method 1:

Start the command prompt. To do this, press the Win + X key combination, then choose Command Prompt (Admin) from the on-screen menu.

taskkill / f / im SearchUI.exe
move% windir% \ systemApps \ Microsoft.Windows.Cortana_cw5n1h2txyewy% windir% \ systemApps \ Microsoft.Windows.Cortana_cw5n1h2txyewy.000
If the commands fail simultaneously, repeat them until the directory is moved correctly.

Method 2:

1.Open the Windows Registry Editor. You can get there by typing “reged” into the search box. Keep in mind that editing the registry can be risky so we recommend making sure that you back up your system

2. Navigate to the Registry key Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows

3. Create a new key named “Windows Search”  Right-click and select New->Key then renaming the folder it creates to “Windows Search.” If Windows Search already exists, navigate to it
