Microsoft has made available for download the Windows Vista Service Pack 1 update which is designed to fix some of the bugs in the operating system and make it more compatible with the myriad range of hardware devices on the market.
But hang on just a second, it seems the update is "wreaking havoc" on some users' computers, according to reports from the US.
If your machine is working fine as it is, you may want to hold off until some of the glitches are identified and fixed.
Vista SP1 isn't like the second service pack Microsoft released for Windows XP, which had heaps of new improvements, particularly when it came to plugging holes in the operating system's security.
It became clear soon after Vista's release, that there were serious problems when it came to finding compatible software drivers to allow everything to work properly with Vista. For that, Microsoft and its industry partners have a lot to answer for.
