Hi all

Our remote apps are going slow after windows 1803 was pushed by Microsoft.

I see others with similar issues recommending rolling back or replacing mstsc .exe with an old version.

 

Is this the only option or is there some possible fix in wse remote app?

 

Server version 2012r2

Alas, I’m afraid that Windows 10 1803 is an absolute mess at the moment (as you’re finding). Personally, I’d roll back to using 1709 (or earlier) if you can. Other than that, you’ll just need to wait it out while Microsoft resolves all of the bugs in it that are affecting RemoteApp programs.

Personally, I’m not experiencing any real slow downs with the RemoteApps per se, but the z-order/window focus issues are completely out of control! Drop-down lists, context menus, etc. don’t display at all when running RemoteApps from a Windows 10 1803 client right now. Again, it’s a real mess!

BTW, I most certainly wouldn’t replace mstsc.exe/mstscax.dll on your client computers with an older (or newer) version (not even as a temporary stop gap measure). I can see nothing but headaches arising from doing that. You’d be much better off just rolling the update back to whatever version of Windows 10 you had previously. You have 10 days to perform a roll-back after installing a newer version of Windows 10. Other than that, just hang tight until Microsoft sends out some Windows Updates that fix the bugs (and keep your fingers crossed that they don’t make things even worse!).

UPDATE #3: KB4284848 has now been released and it addresses the following issue on Windows 10 1803 clients:

Addresses issues with the Remote Desktop client in which pop-up windows and drop-down menus don’t appear and right-clicking doesn’t work properly. These issues occur when using remote applications.

 

Therefore, please make sure that all of your Windows 10 1803 clients have the latest set of Windows Updates installed (including KB4284848) in order to successfully use WHS / WSE RemoteApp from them.

UPDATE #2: According to the following post from Ron Stock (a Microsoft “Sr. Escalation Engineer” in the Support Engineering group), the fix that addresses the “right-click context menu (e.g. pop-up windows)” issue with RemoteApps in Windows 10 1803 will be included in KB4284848 that is (still) scheduled for release in the last week of June:

UPDATE #1: According to the following post from Ron Stock (a Microsoft “Sr. Escalation Engineer” in the Support Engineering group), Microsoft has resolved the RemoteApp window z-order and focus bugs in Windows 10 1803, but won’t be releasing the fix until the last week of June:

Also, here’s a link to a page showing Ron Stock’s other posts (on this subject and others) if you’re interested in reading them (and if you find Microsoft’s lackadaisical response to this issue just as sad and pathetic as the hundreds of others posting in that original thread do):
