Auto driver systems sometimes install incorrect or generic drivers, causing Blue Screens of Death (BSOD). Always have a backup driver before testing.
For users with slow or metered internet, downloading a 6–10GB ghost image once is easier than downloading drivers and software separately for each new PC.
PC repair shops love ghost images. They can restore a customer’s PC to a "like-new" state with all programs included in under 20 minutes, saving hours of manual work.
Many ghosts disable Windows Update via Group Policy or services. Re-enable it and install all security patches. Note: This may break custom themes or activation.
