I’ve read that theCortana.dlloverload issues are caused by the “memory limit” set and/or there is a bugwith the system caching theCortana.dllfilesin their disk image or perhaps there has been a change in your Windows 10 version of Windows. Any suggestions could help resolve the issues. Please keep following all of the new information provided here to keep up with all of the latest developments. Happy Windows 10 updates!
UPDATE: Slight CPU load still present for some users while the search UI and other UI files are being cached. This has been resolved in KB4512941 which has now been released.
I would like to inform all of you that the update that has been pushed or is supposed to be pushed to the consumer version of WP8.1 to address the CPU highload issues is now ready and will be rolled out in a matter of few minutes.
UPDATE 2: There has been a major change to the way that the memory pool handles the task queue size . The memory pool is now split in two smaller chunks of memory to avoid issues which may occur when there are large number of processes consuming the memory pool. The memory pool is being refactored and should be ready for roll out in a few minutes.
UPDATE 3: One important note: The cached version of the Cortana.dll is being released in a later version of KB4512941. I will recommend that users do not install or use the cached version of the Cortana.dll for the time being. The cached version was fixed with the Windows 10 v1903 Cumulative Update and should be fixed again with the Windows 10 v1903.1.6.2 cumulative update.
UPDATE 4: Ihave been told by members of theMicrosoftCommunity thatthe new update has been pushing the Windows 10 Memory Bar . I haveyet to investigate the specific issue and I’m not the developer of theWindowsSecurityBlog, so there may be other issues as well.
UPDATE 3: There are some known issues with the Windows 10 v1903.1.6.2 cumulative update - the Windows 10 Memory Bar issue is now resolved.
UPDATE 4: There has been a change to the Windows 10 v1903.1.6.2 cumulative update which may causememory cache entries to be cleared. However,the cache clearing will take a few seconds.. To see the cached state before the application is launched, you will need to close all open browser windows and relaunch the app.
UPDATE 5: There has been another change to the “SearchUser” cache file. The “SearchUser.dll” has been split in two large chunks . The “SearchUser.dll” will start being released this afternoon and will be removed from the cumulative update .
UPDATE 6: Some more memory capacity issues are found. The performance issue for “Cortana.dll” is resolved. There is also a changeto the “Memory Bar.dll” that causes it to be removed from the cumulative update.
