How to Reboot a Computer

How to Reboot a Computer


Did you know that there's a right way, and several wrong ways, to reboot (restart) a computer? It's not an ethical dilemma—one method ensures that problems don't happen and a myriad of others are risky, at best.
You certainly could reboot your computer by powering it off and on, swapping out the AC power or battery, or hitting the reset button, but each of those methods is a bit of a "surprise" to your computer's operating system.
The result of that surprise could be nothing if you're lucky, but more likely it could cause issues from file corruption up to the very serious problem of a computer that won't even start!
You might be restarting your computer to get to Safe Mode but a common reason is that you're probably restarting your computer to fix a problem, so be sure you're doing it the right way so you don't end up creating another one.

How to Reboot a Computer


To safely restart a Windows computer, you can usually tap or click on the Start button and then choose the Restart option.
As strange as it may sound, the exact method of restarting differs quite a bit between some versions of Windows. Below are detailed tutorials, plus tips on some alternative, but equally safe, ways of restarting.
Before you get started, remember that the power button in Windows typically looks like a vertical line extending out of a full or almost full circle.
Note: See What Version of Windows Do I Have? if you're not sure which of those several versions of Windows is installed on your computer.

How to Reboot a Windows 10 or Windows 8 Computer 
The "normal" way to reboot a computer running Windows 10/8 is through the Start menu:
1. Open the Start menu.
2. Click or tap the Power button (Windows 10) or Power Options button (Windows 8)
3. Choose Restart.

The second is a little faster and doesn't require the full Start menu:
1. Open the Power User Menu by pressing the WIN (Windows) key and X.
2. In the Shut down or sign out menu, choose Restart.

Tip: The Windows 8 Start screen functions a lot differently than the Start menus in other versions of Windows. You can install a Windows 8 Start menu replacement to return the Start screen to a traditional looking Start menu and have easier access to the restart option.

How to Reboot a Windows 7, Vista, or XP Computer 
The quickest way to reboot Windows 7, Windows Vista, or Windows XP is through the Start menu:
1. Click the Start button on the taskbar.
2. If you're using Windows 7 or Vista, click the small arrow next to the right of the "Shut down" button. (Windows XP users should click the Shut Down or Turn Off Computer button.
3. Choose Restart.

How to Restart a PC With Ctrl+Alt+Del 

You can also use the Ctrl+Alt+Del keyboard shortcut to open the shutdown dialog box in all versions of Windows. This is usually only useful if you can't open Explorer to get to the Start menu.
The screens look different depending on which version of Windows you're using but each of them gives the option to restart the computer:

  • Windows 10 and 8: Choose the power icon on the bottom right of the screen to find the Restart option.

  • Windows 7 and Vista: Select the arrow next to the red power button in the lower right-hand corner of the screen, and choose Restart.
  • Windows XP: Click the Shut Down... button and then Restart from the dropdown menu, followed by OK.

How to Use Command-line to Restart Windows 
You can also restart Windows through Command Prompt using the shutdown command.
1. Open Command Prompt.
2. Type this command and press Enter: shutdown /r
The "/r" parameter specifies that it should restart the computer instead of just shut it down.
The same command can be used in the Run dialog box, which you can open by pressing the WIN (Windows) key with the R key.
To restart a computer with a batch file, enter the same command. Something like this will restart the computer in 60 seconds:
shutdown /r -t 60
You can read more about the shutdown command here, which explains other parameters that specify things like forcing programs to shut down and canceling an automatic shutdown.

"Reboot" Doesn't Always Mean "Reset" 

Be very careful if you see the option to reset something. Restarting, also known as rebooting, is also sometimes called resetting. However, the term resetting is also often used synonymously with a factory reset, meaning a complete wipe-and-reinstall of a system, something very different than a restart and not something you want to take lightly.

How to do a hard reboot

To perform a hard reboot or cold reboot, press and hold down the power button on the computer. After 5-10 seconds, the computer should turn off. Once the computer is off, wait a few seconds and then turn the computer back on.

Reboot vs. Restart

The term restart refers to an operating system closing all programs before a soft reboot. The image shows the "Turn off computer" prompt in Windows XP, with the previously mentioned Restart option.

Hard reboot vs. soft reboot


A reboot may be a cold reboot or hard reboot, which means the power was physically shut off and then turned back on. It can also be a warm reboot or soft reboot, which means the system restarted without loss of power.

Difference between bandwidth and latency

Difference between bandwidth and latency Difference between bandwidth and latency is something that confuses a lot of people, but if you are an IT person it would be useful to know the difference between the two because sooner or later you will face a network problem related to it. Part of the confusion has been created by Internet providers by always recommending increase of bandwidth to Internet speed related problem, but as we will see, an Internet connection speed is not always dictated by bandwidth. This part is very important. What is difference between bandwidth and latency? I will give you an analogy to make it easier to understand it if you are still confused. Imagine a highway with 4 lanes where the speed limit is 70 mph. Now on the Internet, bandwidth is the highway, and latency is the 70 mph speed limit. Now if you want to increase the amount of cars that travels through the highway you can add more lanes, but because the highway has too many curves, and

10 things that android phones can do, apple iPhone can`t do

10 things that android phones can do, apple iPhone can`t do Android and iOS both operating systems offer a lot of features (most of them commonly found in both), there are always a few that are exclusively available on that OS.

What is DNS?

What is DNS? The Domain Name System (aka DNS) is used to resolve human-readable hostnames like www.notesshow.blogspot.in into machine-readable IP addresses like 204.13.248.115. DNS also provides other information about domain names, such as mail services. But why is DNS important? How does it work? What else should you know? History of the DNS When the Internet was still in its infancy when you wanted to visit a website you had to know the IP address of that site. That’s because computers are and were only able to communicate using numbers. It’s long, hard to remember, and we (humans, I presume) are not robots. We needed a way to translate computer-readable information into human-readable. And it had to be fast, lightweight. DNS In the early 1980’s, Paul Mockapetris came up with a system that automatically mapped IP addresses to domain names. And the DNS was born. This same system still serves as the backbone of the modern Internet, today. And yet, only a small subs
