It has come to our attention that recent Microsoft updates have impacted a number of users’ Epicor environments in terms of performance. These Epicor Client performance problems manifest most often in significantly decreased speeds and hang time when carrying out processes within the Epicor system. The updates causing the issues were released by Microsoft in both February and April of 2021. Sr Principal Engineer, Epicor ERP Technical Support, Nathan Anderson, has identified one potential resolution in the form of an Epicor Preview Microsoft Fix.

Keep in mind, his article is not a formal recommendation for any one business in particular. This potential fix may be able to alleviate a system’s poor performance as a result of those afore mentioned Microsoft updates. Each customer will need to determine whether or not this fix is appropriate for their system after due consideration of the variables as summarized in KB0108621 and elsewhere. This fix is only meant to remedy system performance issues until an official solution is provided by Microsoft through their official update channel.

A Statement From Nathan Anderson

The steps to apply the preview Microsoft fix below are provided to try to help our customers that have been negatively impacted by these Microsoft updates until the official fix can be delivered by Microsoft through their normal update channel. Epicor ERP Support has made every effort to document this process in a way that would lead to the greatest chance of success while working with the conflicting interest of doing so as quickly as possible.

The steps that follow are technical in nature, and may be beyond what a specific user can successfully execute despite ERP Support’s efforts to streamline the steps to apply a fix to a product we don’t support using a process the author of this knowledge article was first exposed to applying the preview fix being discussed in this article. If there are challenges that prevent the successful application of this Microsoft preview fix, and while ERP Support would not be able to assist there are resources available that would be able to assist further including Epicor Professional Services and Epicor’s Partner network.

  2. The preview fix will not need to be uninstalled for the official Windows patch to be applied when it is released through regular Microsoft update channels.
  3. The preview fix will lead to the same performance behavior outcome as the official fix. This is the final production quality fix.
  4. There is a Local Group Policy adjustment to apply the preview fix (this step will not be required with the official fix from Microsoft). The only difference between the official Windows update and this preview fix is this adjustment required for the preview fix.
