This is a very interesting software package to emulate Vista : http://www.softpedia...formation-Pack.shtml
Many of the components are separate apps. and can be used without the hole package. The package has improved a lot since I last tried it ( V.4) but still needs to polish some. I installed it and then removed it but you can keep some of the functions. Here is a little doodle that goes in circle when the OS is working which I find a plus, that lets me know that something is happening.
The sidebar is well done and after some install problems, seems to work fine. I use it to open Firefox ( with the search gadget), it seems to me that Firefox opens so much faster!!
I emailed the author of the sidebar about some bugs? (decimal weather was a click away) and had an immediate response.
