I have just bough a second hand Windows Vista laptop,and I have exactly the same problem.
The laptop has Windows Vista Home Premium but it does not have any service packs installed. And it took me 3 hours to download and install 100 updates. And after the computer restarts to configure the updates, this also is slow and takes longer than this
does on my Windows 7 laptops.
So it seems that I am not the only one who has found Windows Vista to be slower than Windows 7 and Windows XP. I have several other laptops both Windows 7 and Windows XP. And on Windows XP it only takes about 30 minutes to install over 100 updates, you
have to install on first time set up. And on Windows 7 it takes 40 minutes or 1 hour if you are unlucky.
But on Windows Vista it has taken me twice as long to install all of the updates that I have had to. Because I only bought the laptop 2 days ago.So I am setting it up for the first time.
But it could be because the laptop is second hand and must be quite old. As it only has got Windows Vista home premium WITHOUT Service Pack 1 and Service Pack 2. So when I have finished updating. I will have to install both Service Pack 1 and Service Pack
2. As you have to have Service Pack 2 installed to get any further updates. And you cannot install Service Pack 2 without installing Service Pack 1 first. So in addition to the updates I will have to install 2 service packs.
But on Windows 7 I don't have this problem,as updates take a lot less time to install. And so did the service pack. But it seems on Windows Vista it is a different story.
But it could be the laptop that is the problem.Because it is second hand and an older model. Not the Windows Vista operating system it comes with. But I have all of the Windows Vista software on my Windows 7. That I have installed myself-Windows Mail,Windows
Movie Maker 6 and 2.6,Windows Calendar and Windows Sidebar are all running on Windows 7 without any problems.
But it does seems that Windows Vista is slower than Windows 7 and Windows XP. But as I mentioned it could just be the laptop I am running it on. But if I could run Windows Vista on a new laptop it may be different. Andrea Borman.
