pdf - Memory not Unloading

One of our PC's is not unloading it's memory during certain tasks. The main one is when they choose to print a file to PDF.

• Select File


• Open in Adobe Acrobat


• Print to PDF


• Save and Close

This is what happens with the memory during this process:

This Memory usage goes from Startup > Print one file to PDF (First blue box) > Idle > Print one file to PDF (Second blue box)

• A similar occurrence happened while attempting to resize a file in Paint (reduce it to half size).


• The files that are generally dealt with are .tiff files.


• Each .tiff file is ~500 KB, some might be larger, some smaller, but within ~200 KB of each other. Very rarely there might be a file that is ~1 MB.

I have re-installed Adobe Acrobat in an attempt to fix this, but it has had no effect on the processes.

EDIT: I should note the this is causing severe performance problems. After the second Print to PDF, the PC slows right down, simple tasks (opening a program like paint or word) takes minutes, and if they wanted to Print to PDF again, what might normally take 2-3 minutes, now takes 30 minutes for a single file.

This process (as stated above) would normally take a few minutes to complete multiple Print to PDF's at once, but now, after completing 2 or 3, takes half an hour to print one file to PDF. Sometimes, if a file preview becomes unavailable (taking too long to load the preview in Folder Explorer), it will simply print an empty/blank PDF.

How can I get the memory to unload, or even stop building, so I can print multiple PDF's like I used to?
