If you receive errors when using Windows Update (see the errors in the table below), the System Update Readiness Tool will check for inconsistencies and fix them so you can continue to update your computer through Windows Update. The System Update Readiness Tool is used for:
- Windows Vista-based computers
- Windows Server 2008-based computers
- Windows Server 2008 R2-based computers
- Windows 7-based computers
This update should download automatically; however, if you are still receiving errors, you should download and run the System Update Readiness Tool manually. Learn, in this guide, more about the tool, where to get it, and how to run it.
Please note: Just to reiterate the above, you should only manually download and install this update if you are experiencing unresolved errors (listed below) with Windows Update.
