@pinkadmin : We did not have to uninstall KB2976897, only KB2993651. @StefanSch :  We do not have KB2970228 installed  (I'm pretty sure we either uninstalled or stopped roll out of MS14-045 when Microsoft recommended that customers uninstall around Aug 18 ( see Microsoft pulls MS14-045 and recommends uninstall if you have already deployed | Shavlik BlogShavlik Blog).  You are probably correct in that its a combination of the two that causes the issue, ...

It appears to vary from PDF to PDF ... I do see the A*.tmp files created along with the Z@*.temp files when printing some PDFs.

Uninstalling KB2993651 and rebooting the Citrix server did fix the issue for us The process I used to verify this was: 1. Cleaned up profiles 2. Uninstalled KB2993651 3. Rebooted server 4. Logged in and opened C:\Users\<Username>\Appdata\Local\Temp\<number>\ 5. Opened a PDF and printed it - watched the Z@*.tmp files be created in temp folder 6. Closed Adobe Reader - watched Z@*.tmp files be deleted.   (Historically, the files were not deleted upon closing Adobe Reader) 7. Logged off - confirmed that the profile was indeed deleted. On Citrix servers that still have KB2993651, I can repeat these steps but the Z@*.tmp files are not deleted upon closing Adobe Reader. On a different server, I tried installing Adobe Reader 11.0.09 without removing KB2993651 and the issue was still present so .09 did not resolve the issue. ... View more

However, Adobe Reader s leaving a number of Z@R****.tmp files in Appdata\Local\Temp\<number>\ that are locked and cannot be deleted until the server is rebooted. This is preventing profiles from being deleted properly upon logoff. ... View more
