Microsoft .NET Framework 1.1 Service Pack 1 Update for using SendKeys under Microsoft Windows Vista

This download applies to users of the Microsoft .NET Framework 1.1 Service Pack 1 that need to use the SendKeys functionality while running under Microsoft Windows Vista.

I would recommend using Windows Update. It is the fastest and easiest way to get the Service Pack for one computer.
Check goto Start->All Programs->Windows Update and check for updates. Windows Vista Service Pack 1 should appear in the list.

Hi whs, I checked my updates and i found KB937287-KB938371 were installed. I did not find KB935509 probally not for vista premium.

I found an installation c.d for microsoft service pack 1 for windows vista 32/64-bit-oem on newegg.com. I think i'm just gonna buy and install it i can't seem to find the right sp1 on microsoft website.

@ulyy1: You don't need to buy the Service Pack.
One reason Service Pack 1 won't show up in Windows Update is due to driver problems.
You may need to update some drivers if list to install it.
If that doesn't work you can use the link Lighthouse listed but it's best to use Windows Update as it's a smaller download and it's appearance there means you have the needed Microsoft updates installed that are needed for it to work correctly.

O.k heres what i did i manualy checked for updates in the device manager and sure enough some needed updating. That was a long process glad it's over. I then scanned for updates in windows update and guess what popped up SP1 update WOW. So i'm downloading it now it's much shorter than the one posted in microsoft thats a good thing. Thanks all of you for the help and intresting articles on this subject. Peace and Love.
