I was aghast for reinstallations of Windows 8 because of reasons unknown which ran operating system into trouble.
Now I know why this happened, because I selected maximum number of processors shown in 'Msconfig', which really doesn't exists ('Msconfig' showed 4 processors for Intel Core i3210).
From next start Windows 8 ran into trouble and within a day or two of using this desktop stopped responding, happened for all operating systems where I selected maximum number of processors shown in 'Msconfig'.
Therefore do not select maximum number of processors from 'Msconfig'.
