What Should You Do Before Resetting the Laptop?

1. Backing up your important files on laptop

The first thing you should do is back up the files you want to save on your laptop. Nothing is more frustrating than deleting everything on your device with reckless abandon, only to recall those priceless photos or important documents you only had stored on its drive. There are three simple ways to ensure the security of your data.

Create a system image: A system image is a copy of all data on a drive volume that is ideal for recovering your system after a crash or transferring everything (including minor settings changes) to a new PC. This procedure may appear complicated, but it is quite simple. You only need an extra drive with enough space to save the system image.

Use OneDrive: Microsoft's cloud-based storage solution is ideal for backing up photos, documents, and other files to a secure location before erasing your laptop. All Microsoft users get a free 5GB of storage, and paid plans are available if you require more space. You can easily configure favorite folders to sync automatically to the cloud.

Use an external hard drive: If you’d rather have your files on a physical hard drive (or don’t want to pay for cloud storage), you can save them on an external hard drive. This will take a little longer because you’ll have to manually select the files you want to save and move them to your storage device.

2. Deauthorize accounts and services on your laptop

Even if you find the best price for your old laptop and want to sell it quickly, don't give it away until all services have been deauthorized. Each online service has its procedure for deauthorizing devices, so check with each one before proceeding. This will not affect the number of devices you can use in the future to access personalized content, but it will ensure that no one else can access any of your data stored within those programs on the laptop you intend to sell.

Here are some pointers on how to deauthorize your laptop:

• Take the hard drive out and keep it with you.
• Before selling your laptop, reset or reinstall your operating system to its factory default settings. Ensure that all user accounts have been deleted!
• Check the documentation for each cloud service to learn how to deauthorize devices from their online services. OneDrive, Google Drive, Box, Dropbox, and Facebook are among these services. Ensure that everyone has been successfully deauthorized. The last thing you want is for someone to gain access to any of these programs, steal your data, and use it against you for malicious purposes.
• Before selling laptops, uninstall any unnecessary software.

It may appear that selling old laptops as part of your business improvement processes while keeping some software installed is a good idea. However, doing so may expose your data to unwelcome vulnerabilities.

Uninstalling them is the safest option because it protects your data. If you're not sure which programs to uninstall, remove them all! Removing software may affect the laptop's functionality, but this inconvenience is far preferable to having a stranger gain access to private information.
