How to delete very large System queued Windows Error Reporting files

Windows features a feedback mechanism where it generates error reports from Software and Hardware problems. These reports are stored temporarily in the system and send back to Microsoft so it can find a solution to those problems, and fix it in future updates. As time passes, these reports may take a lot of space on the system. End users are free to delete them using the brand new Free Up Space feature. However, sometimes you won’t be able to do that. In this post, we are sharing how to delete very large System queued Windows Error Reporting files that may run in Gigabytes.

When WER sends out an error file and looks for a solution, the WER server at Microsoft instantly sends out a solution if there is one available.  In case the solution is under investigation or is unknown, the end user gets notified about it and may ask for additional information.
