Restarting a computer is a common troubleshooting step that many of us have been advised to take at some point. Whether it’s to resolve a software issue, update the operating system, or simply to give our computer a fresh start, rebooting can often seem like a magical solution to our technical woes. However, the question of what happens to our data and settings when we restart our computer is a valid one, and it’s essential to understand the implications of this action to avoid any potential losses. In this article, we’ll delve into the world of computer restarts, exploring what happens when you reboot, what gets deleted, and what remains intact.
What Happens When You Restart Your Computer?
When you restart your computer, you’re essentially shutting it down and then immediately turning it back on. This process involves several stages, including the shutdown of all running applications, the termination of system services, and the reset of hardware components. The reboot process can be initiated manually by the user or automatically by the system in response to a software update, a system crash, or other events.
During a restart, the computer’s operating system (OS) goes through a series of steps to ensure a clean shutdown and startup. This includes:
The Shutdown Process
The shutdown process involves the OS notifying all running applications and system services that it’s time to close. This allows them to save any unsaved data, release system resources, and perform any necessary cleanup tasks. Once all applications and services have been terminated, the OS shuts down its own components, and the computer’s power is turned off.
The Boot Process
When the computer is turned back on, the boot process begins. This involves the BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) firmware initializing the hardware components, loading the OS into memory, and starting the system services. The OS then takes over, loading device drivers, starting applications, and restoring the system to its previous state.
What Gets Deleted When You Restart Your Computer?
Now, let’s address the question of what gets deleted when you restart your computer. The answer is not a simple one, as it depends on various factors, including the type of data, the operating system, and the specific configuration of your computer.
In general, temporary files and data stored in the computer’s RAM (Random Access Memory) are deleted during a restart. This includes:
Temporary Files
Temporary files are created by applications and the OS to store data temporarily while it’s being processed. These files are usually deleted when the application is closed or when the computer is restarted. Examples of temporary files include cache files, log files, and temporary documents.
Ram Data
Data stored in the computer’s RAM is volatile, meaning it’s lost when the power is turned off. This includes any unsaved data in applications, such as unsaved documents or unfinished tasks.
On the other hand, data stored on the computer’s hard drive or solid-state drive (SSD) is not deleted during a restart. This includes:
Permanent Files
Permanent files are stored on the computer’s hard drive or SSD and remain intact even after a restart. Examples of permanent files include documents, images, videos, and installed applications.
System Settings
System settings, such as user accounts, network configurations, and display settings, are also preserved during a restart. These settings are stored in the OS’s registry or configuration files and are loaded when the system starts up.
What Remains Intact After a Restart?
As mentioned earlier, data stored on the computer’s hard drive or SSD remains intact after a restart. This includes:
Installed Applications
Installed applications, including their settings and data, are preserved during a restart. This means you won’t have to reinstall your favorite software or reconfigure its settings every time you restart your computer.
User Data
User data, such as documents, images, and videos, is also preserved. This means you can rest assured that your important files will still be there after a restart.
System Configurations
System configurations, including network settings, display settings, and user accounts, are preserved during a restart. This ensures that your computer is configured correctly and ready to use when you start it up again.
In summary, restarting a computer does not delete everything. While temporary files and data stored in RAM are lost, permanent files, system settings, and installed applications remain intact.
Best Practices for Restarting Your Computer
To minimize the risk of data loss and ensure a smooth restart, follow these best practices:
Save Your Work
Always save your work before restarting your computer. This includes saving any open documents, spreadsheets, or other files.
Close Unnecessary Applications
Close any unnecessary applications before restarting your computer. This helps prevent data loss and ensures a clean shutdown.
Use the Proper Shutdown Procedure
Use the proper shutdown procedure to restart your computer. This involves clicking on the Start menu, selecting the Power option, and choosing Restart.
By following these best practices and understanding what happens when you restart your computer, you can ensure a safe and successful reboot every time.

| System Settings | No |
In conclusion, restarting a computer is a common and necessary task that can help resolve software issues, update the operating system, and improve overall system performance. While it’s true that some data is deleted during a restart, such as temporary files and RAM data, permanent files, system settings, and installed applications remain intact. By understanding what happens when you restart your computer and following best practices, you can ensure a safe and successful reboot every time.
What happens to my files when I restart my computer?
When you restart your computer, your files and documents remain intact. The operating system and applications may close, but the data you have saved on your hard drive or solid-state drive is preserved. This is because the files are stored on the computer’s storage device, which is not affected by the reboot process. The operating system, on the other hand, is loaded into the computer’s memory (RAM) when you start up, and it is cleared when you shut down or restart.
However, it’s essential to note that any unsaved work or data in applications that are not properly closed may be lost during a restart. This is why it’s crucial to save your work regularly, especially when working on important documents or projects. Additionally, if you have any external devices connected to your computer, such as USB drives or network shares, they may be disconnected during a restart, and you may need to reconnect them when the computer starts up again. To avoid any potential data loss, it’s always a good idea to save your work and close any open applications before restarting your computer.
Will restarting my computer delete my installed programs and applications?
Restarting your computer will not delete your installed programs and applications. The installation files and data for these programs are stored on your computer’s hard drive or solid-state drive, and they remain intact even after a reboot. When you restart your computer, the operating system loads the necessary files and configurations for each installed program, allowing you to use them again as usual. This means that you can restart your computer without worrying about losing your installed software or having to reinstall them.
However, it’s possible that some programs may not retain their settings or configuration after a restart, especially if they are not properly closed or if there are issues with the program’s installation. In some cases, a restart may also cause issues with certain programs, such as those that require a constant internet connection or those that are running in the background. To minimize any potential issues, it’s a good idea to close any open programs and save any work before restarting your computer. This ensures that all programs are properly shut down and can start up again without any problems when the computer restarts.
Can restarting my computer remove viruses and malware?
Restarting your computer may temporarily remove some types of malware, such as those that are loaded into memory (RAM) when the computer starts up. However, this is not a reliable method for removing viruses and malware, as many types of malicious software can survive a reboot and continue to cause problems. In fact, some malware is designed to restart itself after a reboot, allowing it to continue running and causing harm to your computer. To effectively remove viruses and malware, you need to use specialized software, such as antivirus programs, which can scan your computer and remove any malicious files and configurations.
It’s also important to note that restarting your computer in safe mode may help to remove some types of malware, as this mode loads a minimal set of drivers and services, making it more difficult for malicious software to run. However, even in safe mode, some malware may still be able to operate, and you may need to use additional tools and techniques to completely remove it. To protect your computer from viruses and malware, it’s essential to use a combination of antivirus software, firewalls, and safe computing practices, such as avoiding suspicious emails and downloads, and keeping your operating system and software up to date.
