Issues updating xp service pack 3
Microsoft wonders why developers and users don’t trust them, then they pull arrogant and easily avoided stunts like this.
We’ve been filling the pages of Office Watch with Office update woes for years and Microsoft persists in making them a painful experience for their customers.
Because of these problems we cannot recommend anyone install Office XP SP3 at this stage.
Microsoft is being typically silent on the matter, and none of the common compatibility problems are even hinted at as ‘Known Issues’ with the update.
Visit Stack Exchange I am going through an agonizing re-install, on day three now of Windows Updates, VS Service Packs, etc.
It's been tough having to download all this again on a 384kbps ADSL line.
ADDENDUM: Many people are giving answers that involved downloading.
Step 2 - Fetch the latest security updates (released after SP3) Take a look at the Microsoft Security Bulletin Search tool to determine which updates you'll need to download.
Here are the settings I recommend to get all of the relevant updates after post-SP3 Then it's just a matter of downloading the relevant install executables for offline use.
Please keep in mind, however, that for most users the easiest way to install the latest Microsoft Office service pack is to run Windows Update.
In fact, this is the only way to receive cumulative updates to Microsoft Office 2016, which, like Windows 10, no longer receives service packs in the traditional sense.
 Microsoft Office 365, the subscription-based version of Office 2013, automatically includes the SP1 updates found in Office 2013. Microsoft Office 20 are the only versions of Office available in a 64-bit version.
