Vista's user account protection caused problems with Visual Studio 2005, and Microsoft addressed this with the Visual Studio 2005 Service Pack 1 Update for Windows Vista. I'm having similiar problems running VS2005 on Windows 7, but I can't find any info from Microsoft directly addressing this. Should I just install the Vista service pack onto Windows 7?
But what are the chances of reverting back? How many times have you uninstalled a Windows update, let alone a complete service pack update? If your answer is never or hardly ever, you might want to consider removing the backup files. All in all this can free up over half of gigabyte of hard disk space.
Running with Vista Service Pack 1
Since Vista Service Pack 2, the vsp1cln.exe program has been replaced by compcln.exe, which can be used to make the service pack changes final. The command can be run from the command prompt or directly from the Start menu, in which case you will need to click Continue in the UAC window.
Please keep in mind that after running the compcln.exe command you will no longer to be able to revert back to SP1 or even Vista without a service pack level. So only run the command if you need the disk space, and have been running Vista with SP2 for some time without problems.
There were two Vista service packs. Support for the first ended Tuesday, while Service Pack 2 will continue to receive mainstream support until April 10, 2012, and the more limited "extended support" until April 11, 2017. Once support for a service pack ends, that software no longer receives security updates.
In the Windows Team Blog, Microsoft said: "We recommend folks look at upgrading to Windows 7, which is the fastest selling operating system in history, selling over 400 million licenses to-date. Windows Vista users can also use Windows Update to update their PC to the latest service pack available which is Service Pack 2 (SP2)."
Since Vista was never that popular, the bigger issue applies to users of Windows XP, still the most widely used version of Windows. All support of Windows XP Service Pack 2 ended last year, but XP's third service pack is on extended support until April 8, 2014. According to Microsoft, sales of PCs with XP pre-installed ended last year and sales of PCs with Vista pre-installed will end in October of this year.
Note: Machines running Windows XP and Vista are seriously old hardware that may not be up to the task of running Zoom. Windows XP came out in 2001 and ceased to be sold in 2007 with Windows Vista coming out in 2007 and being replaced by Windows 7 in 2009.
