A solution would obviously be to disable automatic updates but that’s probably not a preferred solution by many as well. The easiest way to block the automatic download and installation of both Windows XP Service Pack 3 and Windows Vista Service Pack 1 is a Registry key that has to be added to the Registry that prevents the installation for twelve months.

The update problems should be sorted out by that time and if they have not been it is still possible to disable automatic updates. To add the entry to the Registry do the following. Press Windows R, type regedit, hit enter.

The Registry opens and we need to navigate to the key HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate and create a new DWORD named DoNotAllowSP there. The value of the DWORD has to be set to 1.

An alternative would be to create a new text document, paste the following three lines into it and rename the document to block.reg afterwards.

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate]
"DoNotAllowSP"=dword:00000001

A double-click creates the new Registry key automatically. The block can be removed by either deleting the Registry key again or by setting the dword value to 0 instead.
