so i have windows vista and lately its been crapping out on me when i try and log on it says it cant log me on to my profile and puts me on a temp and also has gotten rid of alot of my stuff i have saved on the desktop. so i decided that i was gonna upgrade to windows 7 but the uprade advisor said i have to download sp1 for vista but it doesnt work even when i dl it from the microsoft network it just comes up with errors. does anyone know if i really need to download it or if i can just upgrade. and will upgrading get rid of my log on problems.

There's a strong possibility that your current problems with Vista come from the fact that you don't have Service Pack 1. Strange that your OS refuses to install the SP1. What kind of errors are you getting exactly?

it says error: 0X800F0900 and then tells me to go to go.microsoft.com/fwlink/?linkid=101139 and that didnt really help. should i just try and install the windows 7 or would it not work.

That error indicates that your Windows update manager doesn't work any longer. You have to get a patch from the Microsoft website... If you're unable to download and install whatever patch/update, maybe try to repair your OS with the original Vista installation disk... You also might want tot check this topic which handles the same problem you seem to have...

do you happen to know where i can find that patch or the name of it.

so it wont even let me reinstall my current OS so i dont know what to do anymore.

Most computers can be reset to factory settings during boot up.Check manual for something like pressing the f10 key while the makers logo comes up while booting.Save everything beforehand,of course.

Try In-place upgrade first. If it still does not work, as H2o_Guy said, restore the computer to factory settings and then upgrade to Windows 7: In-Place upgrade (Repair install) =========== 1. Start the computer by using the current Operating System. 2. Insert the Windows Vista DVD in the computer's DVD drive. 3. Use one of the following procedures, as appropriate: If Windows automatically detects the DVD, the Install now screen appears. Click Install now. If Windows does not automatically detect the DVD, follow these steps: a. Click the Start Button, type Drive:\setup.exe in the start search box and then click OK. Note: Drive is the drive letter of the computer's DVD drive. b. Click Install now. 4. When you reach the "Which type of installation do you want?" screen, click Upgrade to upgrade the current operating system to Windows Vista.Vivian Xing - MSFT
