I remember the first time I saw single click option in Windows.It was in the days of good old Windows 98 where making “web” like desktop was cool,you simply clicked on icons and they opened as if they were web links.
Fast forward to Windows Vista.The way to turn on single click on icons here is by changing the default setting in Folder options.
Launch explorer in Vista (not the internet explorer but the Windows explorer).This can be done by going to Start > Run > explorer.exe The quickest way is to simply double click My Computer or any other folder.
Select Organize > Folder and Search Options.
Over there enable the option Single click to open an item feature.
And so you get a one click Vista which can be quite useful for those who are not exactly fond of double clicking.
Peace and happy single clicking.
