Many have already arrived in the Berkshire town, camping out be-decked in Union Flags, to secure a good vantage point.
There is also a heavy police presence, with armed officers stationed around town and other officers on top of buildings looking over the crowds.
Well wishers gathered in Windsor will be hoping to catch another glimpse of the bride or groom before the big day.
Harry accompanied his brother Prince William, now the Duke of Cambridge, on an impromptu walkabout outside Clarence House, in central London, the evening before his wedding to Kate Middleton.
Crowds in Windsor will be hoping to see the prince before he spends his final night of bachelorhood at the Dorchester Collection's Coworth Park in Ascot.
The bride will stay at the Cliveden House Hotel, set in a National Trust estate in Taplow, Berkshire, with her mother.
Those hoping to travel today and catch a glimpse of Harry and Ms Markle's carriage procession through the Union flag-lined streets have been advised to catch trains as early as 4am.
Millions more will choose to avoid the hassle, instead watching the wedding on television from an armchair or sofa in the comfort of their own homes.
The BBC has waived the licence fee for communities wanting to watch the ceremony together, with hundreds of street parties and other events planned around the country.
In Norfolk, there will be big screens at Sandringham and Norwich Cathedral, while a number of pubs and other venues will be screening the wedding before the day's other big event - the FA Cup Final.
News organisations - including the EDP - will have live coverage online, meaning you can keep up to speed with events in Windsor on your mobile phone.
Those wanting to continue the celebrations into the night can enjoy an extra two hours in the pub thanks to extended licensing hours.
Pubs in England and Wales can stay open until 1am.
We'll have live coverage from Windsor on EDP24 from tomorrow morning.
