Often, an operating system will become corrupted, slow or unstable over time. Sometimes, the best thing to do is to reinstall the OS completely. Here’s a quick guide to help you reinstall Windows 7. Have your Product Key handy. It’ll often be written on your PC’s case, or be included inside the box that Windows 7 came in.
All your important documents should be backed up using an appropriate method. While Windows tries to save your old operating system in the Windows.Old folder, it doesn’t always succeed. Plus, you may not have the space to save an entire backup and may only want to back up critical files.
Put your Windows 7 disc in the drive, but close the window that pops up. We’re going to boot from it instead.
Hit Control-Alt-Del and choose to restart. If the PC is frozen, turn it off and back on. Before the Windows logo appears again, hit DEL or F2 to enter the BIOS (depending on your PC). Under Advanced Boot Options, choose the CD or DVD drive as the first boot option. Save and quit. Your PC will boot from the Windows disc.
After you reinstall Windows 7 , you can restore your important files from your backup. You may need to install licensed applications again, such as Microsoft Office. Also, be sure and run Windows Update until your copy of Windows 7 is fully updated. You should experience fewer errors with a fresh install. Good luck!
