eg.
PC - A  = Its your Own Computer
PC - B  = RDP  PC - 1
PC - C =  RDP PC - 2 (Inside RDP PC1)

Here's the scenario: I Remote Desktop from Computer A to Computer B and from Computer B to Computer C.

(1) I want to send Ctrl+Alt+Del to Computer A, I type Ctrl+Alt+Del from Computer A

(2)  want to send Ctrl+Alt+Del to Computer B, I type Ctrl+Alt+End  inside Computer B

(3) If I want to send Ctrl+Alt+Del to Computer C, I open the On-Screen Keyboard on Computer C and use it to type Ctrl+Alt+End, which sends Ctrl+Alt+Del to Computer C

OR  

If I want to send Ctrl+Alt+Del to Computer C, I type Shift+Ctrl+Alt+End  inside Computer C.

How to Block Websites without using any Software

1.) Open “Run” from the start menu (or press WinKey + r). Just copy paste the following path and hit ENTER.

notepad %windir%\system32\drivers\etc\hosts

Alternately, go to C:\Windows\System32\Drivers\Etc and find the file “hosts”. Open that file in Notepad.

2.) When this hosts file is opened in Notepad, at the end of the file you will see something like “127.0.0.1 localhost”.

3.) Under “127.0.0.1 localhost” just add another website URL that you want to block.

For Example:-

127.0.0.1 localhost
127.0.0.2 www.kalpesh.biz
127.0.0.3 www.consumer-complaints.in

4.) Make sure every time you add another website, the last digit of the address 127.0.0.x should not be the same.

5.) Save the file and exit.

So, here you go. Restart your browser if it is opened and changes will take place immediately.

The good thing is that no message, no pop ups nothing will be displayed when someone tries to open a blocked website. Your browser will just fail to open those websites without any error messages.
