Windows 10 update addresses memory leak bug, Your Phone app issues

Windows 10 memory leak bug

In the Release Preview and Beta Channels, Microsoft has started
testing a new cumulative update that will address multiple
memory leak problems in Windows 10. In addition to performance
improvements, Microsoft is also fixing an issue that prevented
users from accessing Your Phone app-based Android apps.

In any operating system, apps occupy a block of RAM to manage
their processes, features, etc. Those apps typically release
their block of memory when it’s no longer needed. In some
cases, a memory leak could take place and only a portion of the
occupied memory will be released.

Windows 10 users recently discovered a bug where the ctfmon.exe
process won’t release the block of RAM occupied for its apps.
The ctfmon.exe process is typically used in apps with
“Alternative User Input” and it is required to control certain
apps using via pen, speech or keyboard inputs.

Build 19043.1023, a new update available for testing in the
preview channels addresses the memory leak bug in ctfmon.exe.
The memory leak was observed when users refreshed an app that
has an editable box. Another memory leak bug associated with
“PKU2U” (a security feature) has been addressed.

bridge the gap between Windows and Android world.

The Your Phone app was updated with support for “phone apps”
last year. This feature offers a way to seamlessly run Android
apps on your desktop and make them behave like Windows apps.

Android apps streaming on Windows have their own window, Start
Menu, notification center integration, and taskbar entry.
Microsoft even lets you pin apps on the taskbar, but there’s a
catch – some users observed that it’s no longer possible to
launch apps pinned to the taskbar when they installed Windows

In the latest update, Microsoft addressed an issue that
prevented some folks from opening apps that are pinned to the
taskbar. This issue was experienced after users upgraded to the
most recent version of Windows 10.

Another related bug has been fixed where the Progressive Web
App (PWA) icons appear as blank when you pin them to the

These fixes will be included in June’s Patch Tuesday release.
