Although we have tested Windows 10, and haven't seen any MAJOR problems with the operating system itself (from a clean installation)... we do have one machine in the shop now that has experienced major data loss due to the customer's attempt to upgrade from Windows 7 to Windows 10. So, before you attempt to do an 'in place upgrade'... if you have data you do not want to potentially lose (pictures, documents, email, etc.)... BACKUP-BACKUP-BACKUP before attempting the free upgrade!!! If you do not know how to backup all your data, or are unsure, we have backup and imaging services and/or can perform your upgrade for you to ensure you have no catastrophic data loss - and to ensure your computer is working smoothly with Windows 10! Call or contact us today for more information!
