Free Guide to Resetting Your Computer

Understanding What Resetting Your Computer Means

A computer reset is a process that returns your device to a state similar to when it first came out of the box. This guide explains what happens during a reset and why people choose to do one. Resetting is different from restarting—restarting simply turns your computer off and back on, while resetting wipes your files and settings.

When you reset a computer, the operating system gets reinstalled or restored to factory settings. This means personal files, photos, documents, programs you installed, and custom settings all get removed. According to Microsoft, over 40% of computer slowdowns are caused by accumulated software and files that build up over time. A reset can address this by clearing out years of digital clutter.

There are generally two types of resets available on most computers. A soft reset removes personal files and reinstalls Windows or macOS but keeps some system files intact. A hard reset, sometimes called a factory reset, removes nearly everything and restores the computer to its original state. The choice between these depends on your situation and what you want to preserve.

People reset computers for several reasons. Some want to fix persistent problems like constant freezing or crashing. Others are preparing to sell or give away a computer and want to erase personal information. Some simply want a fresh start after their device has accumulated problems over several years of use. Understanding your reason helps determine which type of reset makes sense for your situation.

Practical takeaway: Before doing anything else, think about why you want to reset. Write down your reason—this will help you decide which reset method is right for you and whether you need to back up any files first.

Backing Up Your Files Before Resetting

Before you reset your computer, you need to save any files you want to keep. A reset will delete most or all of your personal data, so backing up is a critical first step. There are several ways to back up your computer, ranging from simple to more thorough.

The most straightforward method is using an external hard drive. You can purchase external drives at most electronics stores for $50 to $200, depending on storage capacity. To back up using an external drive, you simply connect it to your computer and copy over the folders you want to save. Windows computers have a built-in backup tool called File History that can automate this process. For Apple computers, Time Machine serves the same purpose. These tools create backups of your files so you can restore them later if needed.

Cloud storage is another option for backing up important files. Services like Google Drive, Dropbox, and Microsoft OneDrive let you store files online. This method is particularly useful if you only need to save documents, photos, and small files. Many of these services offer free storage ranging from 5 to 15 gigabytes, which is enough for thousands of documents and photos. If you have large video files or want to back up hundreds of gigabytes, you may need to pay for additional storage, typically $10 to $20 per month.

A practical approach combines both methods. Use cloud storage for your most important files—documents, photos, financial records—and use an external hard drive for larger items like videos or music libraries. This way, your critical files are protected in multiple locations. According to data backup studies, people who maintain backups in two different locations recover their files successfully 95% of the time when problems occur, compared to just 40% for those with single backups.

Before backing up, take time to organize your files. Locate all the folders and files you want to keep. Common places to check include your Desktop, Documents folder, Pictures folder, Downloads folder, and any specialized folders where you save work. Make a list of programs you use regularly—while resetting won't preserve installed programs, knowing which ones you had helps you reinstall them afterward.

Practical takeaway: Spend 30 minutes identifying and copying your important files to either an external drive or cloud storage. Don't skip this step—once you reset, deleted files are extremely difficult or impossible to recover.

How to Reset a Windows Computer

Windows computers have a built-in reset feature called "Reset this PC" that makes the process straightforward. This feature is available on Windows 10 and Windows 11, which together run on over 1.4 billion computers worldwide. The reset process takes between 20 minutes to several hours, depending on your computer's speed and which reset option you choose.

To start a Windows reset, go to Settings, then find "System" or "Recovery" depending on your Windows version. Look for an option that says "Reset this PC" or "Reset your computer." Windows will present two choices: "Keep my files" or "Remove everything." The "Keep my files" option removes programs but preserves your personal documents and photos. The "Remove everything" option is a complete reset that deletes nearly all personal data.

Once you select which type of reset you want, Windows will ask if you want to remove files locally or reinstall from the cloud. Removing files locally takes longer but doesn't require a strong internet connection. Reinstalling from the cloud is faster if you have reliable, fast internet. Windows will then show you a list of programs that will be removed—review this list to make sure you're prepared to lose access to these applications.

During the reset, your computer will restart multiple times. This is normal and expected. You'll see a progress bar showing the reset's status. Don't unplug the computer or force it to shut down during this time, as this can cause serious problems. The reset process requires your computer to have enough battery power (if it's a laptop) or should be plugged in during the entire procedure. Budget at least two to four hours for a complete reset, and avoid using the computer during this time.

After the reset completes, your computer will restart and ask you to set it up like a new device. You'll enter your Microsoft account information, set your privacy preferences, and choose your language and keyboard settings. Once setup finishes, you can start installing programs again and restoring your backed-up files.

Practical takeaway: Before starting a Windows reset, write down which programs you use most frequently. After the reset completes, you can reinstall them in order of importance rather than trying to remember everything you had.

How to Reset a Mac Computer

Apple computers use a different reset process than Windows machines, but the concept is similar. Macs have several reset options depending on what you're trying to accomplish and which macOS version you have. The most common reset method is called "Erase and Reinstall," which removes everything and installs a fresh copy of macOS.

To reset a Mac, restart your computer and hold down Command + R during startup. This launches Recovery Mode, which is a special operating system that runs separately from your main system. In Recovery Mode, you can access tools for resetting or repairing your Mac. Look for the option called "Disk Utility" and select it. From there, you'll select your main hard drive and click "Erase," which will format the drive and prepare it for reinstallation.

After erasing the drive, exit Disk Utility and select "Reinstall macOS" from the Recovery Mode menu. Your Mac will download and install a fresh copy of the operating system. This process can take one to three hours depending on your internet speed and Mac model. You'll need a stable internet connection for this entire process, so consider using a wired connection if your Mac supports it, as this is more reliable than Wi-Fi.

For newer Macs with Apple Silicon chips (the M1, M2, and M3 processors), the reset process is similar but uses updated tools. These newer machines may offer additional options like starting fresh or keeping your files. Check Apple's official support documentation for your specific Mac model, as the exact steps vary depending on your hardware.

After the macOS reinstallation completes, your Mac will restart and ask you to set up your device. You can sign in with your Apple ID and restore your backed-up files using Time Machine if you created a backup before resetting. You'll need to reinstall programs like web browsers, email clients, and other applications you use regularly.

Practical takeaway: If you have a backup created with Time Machine before resetting, keep that backup drive nearby after your reset. You can restore files from it within the first few hours after setup, before you start installing new programs.
