These include issues with Explorer using large amounts of memory, crashes, and reduced performance.

But that’s far from the only fix to be found in the cumulative update.
In a Windows Insider blog post, Microsoft reveals a number of important bug fixes, including those affecting Explorer and general performance:
- Fixed an issue that displayed nothing or indefinitely displayed “Computing Filters” when filtering File Explorer search results.
- Fixed an issue with a heap leak that could cause explorer.exe to consume large amounts of memory.
- Fixed an issue that caused multiple instances of explorer.exe to run on a system when AppLocker is enabled and the system is not on the Internet.
- Fixed an issue that could cause File Explorer and other apps to stop responding for several minutes. This problem occurs after a client reconnects to the corporate network and tries to use mapped drives to access file shares on the corporate network.
And there is, of course, the most important printer solution:
- Fixed an issue that could cause a blue screen when attempting to print to certain printers using certain applications and could result in the APC_INDEX_MISMATCH error.
The full list of improvements can be seen in the blog post.
