I said that installing Windows 7 Service Pack 1 would be absolutely smooth and hassle free. I do then a "mea culpa" because I have not considered that with Windows and Microsoft you can never be too calm and that the SP1 can give errors during the update .
Let's start by saying that computers, in some ways, are like people: nobody is the same as another. Even taking two absolutely identical PCs, assembled with the same pieces and with the same programs inside, they can react in different ways to the same operation. Despite the sure efforts of Microsoft, therefore, it can happen that for 90% of the computers in the world, the installation of a Windows update is successful while the others receive errors and the installation fails .
For example, on three computers where I installed Windows 7 Service Pack 1, one of them failed giving me an 80072EFE code. Searching the internet for 80072EFE, you can see numerous reports from the forums, where experts recommend a thousand different solutions.
In the end I relied on the tools I knew and I solved the problem.
If the Windows 7 Service Pack 1 update fails, the problem depends on the error code that you see directly on the screen or in the Windows event log. Regardless of this code which can be the 80072EFE or 800F0A12 or other, in general it definitely resolves (here I play the career of blogger) by following the following steps.
1) First, it is imperative to be sure that you don't have viruses and malware on your computer .
Even small, non-operating malware can compromise the installation of the Windows update in general. On the forums all the advice is about malware but wrong. If, by scanning with antivirus, no viruses are found or if you do not have any symptoms of infection, 99% of the error of Windows Update does not depend on this. Before wasting a lot of time doing long, deep virus scans, it is worth checking that the internal functionality of Windows 7, Windows Update, has no errors .
2) A possible cause of the error can derive from your internet connection which, for some reason, is unable to carry out the download of the Service Pack. This diagnosis is very likely if all the other updates work well and only the Service Pack goes into error. In particular, the problem may be in the connection to the Wifi router, therefore, I recommend trying to update by connecting the computer to the internet via Ethernet cable .
3) If the error recurs, the first thing to do is to use the Windows problem detection tool, accessible from the Control Panel.
Under the " System and Security " section, you can click on " Troubleshoot Windows Update ". Proceeding with the automatic resolution tool, Windows does everything by itself and allows you to restore its correct functioning. A click on Next starts a scan which should take less than 30 seconds.
4) If the update fails again, download and install the Microsoft Fix IT tool.
This automatic tool I mentioned in the article on how to fix Windows Update errors, requires restarting the computer and completely clears the history of the Windows Update, resetting it. Restarting the computer, you will notice, starting Windows Update from the Windows Start menu, that you have to perform a new search for updates and that the computer sees written " 0 updates installed " and " Last check: Never ". In my experience, everything went well at this point.
5) If an error still occurs, there is another Microsoft tool. You need to download the system update compliance analysis program for Windows 7 . Make sure to download the tool compatible with the 32 or 64 bit operating system. This tool checks if there is an inconsistency in Windows services that could prevent the correct installation of future updates, Service Packs and software.
The repair tool has a size of approximately 100 Megabytes for 32-bit systems and 300 Megabytes for 64-bit systems. This also does a computer scan which typically takes 15 minutes. If it takes you longer and seems to be stuck, still let go without canceling the operation.
6) If the Windows SP1 update still does not work, there is probably a virus that is hidden in memory, which the antivirus does not see.
In this case, arm yourself with holy patience and follow the guide to remove malware and viruses from your computer. In summary, you must first download Malware Bytes and do the complete scan.
If the update still does not work, download ComboFix which eliminates viruses when the PC starts, from the live CD, therefore with Windows not running.
After all this, I have no doubt that the Service Pack 1 update issue is resolved.
