Protect your data
BitLocker encrypts your whole drive, so a lost or stolen laptop does not expose your documents, passwords or client files.
Work from anywhere
Remote Desktop lets you sign in to your home or office PC from another computer, tablet or phone and use it as if you were sitting in front of it.
Take control of your PC
Group Policy gives you settings that Windows 10 Home hides, from update behaviour to privacy and security rules. Hyper-V and Windows Sandbox let you test software and other operating systems safely.
Why Upgrade Instead of Reinstalling?
-
Nothing to back up or restore: your programs, files and personal settings are untouched.
-
No installation media: the upgrade happens inside Windows Settings.
-
Fast: most PCs finish in under 15 minutes.
-
Same PC, more capability: ideal when a new job, course or client requires Pro features.
