Many Windows users access their emails from web browsers - Internet Explorer, Firefox, Google Chrome, Safari etc etc. This means your emails are in the “cloud” and are not necessarily under your direct control.
If you have multiple email addresses then you will need to log into each email provider’s mail site. I-Pad users can register their various email addresses into a single email app, which then provides them with a list of all their emails no matter where they came from - very tidy!.
Some Windows users will have had Microsoft Office installed, which has a product called Outlook. This has a similar function to the I-Pad app. Microsoft Office costs over £100 to buy, which if you want a Word Processor, Spreadsheet, Presentation, Email and other software then it may be worthwhile paying this price.
