Assessing Performance and Disk Space Issues

  • Article

Applies To: Windows 7, Windows Vista

The Update Compatibility Evaluator (UCE) can experience performance and disk-space issues. If you notice either of the following symptoms, the UCE has been deployed on too many computers.

Symptoms

  • Performance and connection issues. Too many connections made to your file share can reduce your computers' performance or prevent your computers from connecting and uploading to the file share.

  • Lack of free disk space. Your log files might use all of the free disk space on the computer containing the file share.

The following three options are available for fixing this issue:

  • Create and deploy a new data-collection package that generates log files locally to the client computer. After generating the log files locally, use server-management software such as System Center Configuration Manager 2007, formerly known as Microsoft® Systems Management Server (SMS), to pick up the log files and transfer the information to your file share.

  • Uninstall the UCE and the Microsoft Application Compatibility Toolkit Data Collector (ACT-DC) from some or all of the computers to which they were deployed.

  • Disable the file share to ease network traffic. The file share increases the use of disk space on the computer to which the UCE is deployed (up to 60 MB of .xml files per day until you uninstall the UCE).

Important

When the file share becomes available after being offline, the ACT-DC will try to upload all of the log files that failed while the share was down. This could potentially result in a large network load.

Manually Uninstalling the UCE

You can manually uninstall the UCE before it finishes and then uninstalls automatically. This might be necessary if the compatibility evaluator was deployed to too many computers, or if the computer to which it is deployed is experiencing performance issues.

To manually uninstall the UCE

  1. Open a Command Prompt window on the computer from which you will uninstall the UCE.

  2. At a command prompt, type MsiExec.exe /qn /X{DC93B45B-D4F5-4FFE-9B47-042BD6FA8CC5}.

Note

Repeat these steps manually on each computer or through server-management software, such as Configuration Manager 2007.
