System resources, such as file data, registry data, and even in-memory data, can develop inconsistencies during the lifetime of the operating system. These inconsistencies may be caused by various hardware failures or by software issues. In some cases, these inconsistencies can affect the Windows Servicing Store, and they can cause a Windows update to fail. When the update fails, it blocks the user from installing updates and service packs.
System Update Readiness Tool
System Update Readiness Tool or CheckSUR addresses this issue. These updates contain the Check for System Update Readiness (CheckSUR) tool. The CheckSUR tool will scan for inconsistencies on your computer and fix them as it’s being installed. Please note that the scan may take up to 15 minutes or longer to run on certain computers. Even if the progress bar seems to stop, the scan continues to run, so do not cancel the process.
