Part 1: Downloading McAfee Removal Tool and WSUS Offline Update on Another Computer
Theres a few recommended downloads which should ideally be ran from a patched computer…
Windows 7 and Windows 8.1
As you are likely following this guide after a restore from Dell Windows 7 or 8.1 Factory Settings, its a good idea to download the McAfee Removal Tool and WSUS Offline Updates (do not apply the WSUS Offline Updates until McAfee is removed) on another computer.
- McAfee Removal Tool
- Download WSUS Offline Update, including IE11, Silverlight, Microsoft Security Essentials (Windows 7), Microsoft.Net, Windows Live Essentials 2012
Special notes for Windows 8.0 Factory settings, these factory settings should be considered as a write off. Clean installation of Windows 8.1 is recommended due to the awkward deployment of Windows 8.1 via the Microsoft Store resulting in dreadful system performance. It'll actually be faster to clean install Windows 8.1 than download and apply all the updates via Windows Update and the Store.
Part 2: Uninstalling McAfee
To stay Offline via this procedure press [Fn] and [F2] to turn your wireless off (just [F2] in some systems depending how you've configured your function keys, other systems have a wireless switch on the side of the computer). Alternatively disconnect the ethernet cable.
Close down all programs and go to the Desktop (if you are on the Start Screen press [Windows] and [d]) and start Windows Explorer.
