When you install Adobe Reader XI in your computer two processes related to it AdobeARM.exe and reader_sl.exe are automatically set to run at startup, you can notice them running under the Processes tab in Task Manager. Let us see more details about these two processes before knowing how to disable or delete them.
AdobeARM.exe is Adobe Reader and Acrobat Manager that checks for Reader updates and installs them when found without requiring intervention of the user. Adobe Reader is configured to automatically install updates to keep you always on a secured version.
On the other hand, reader_sl.exe is another process that has the description Adobe Acrobat SpeedLauncher and it runs from the path ‘ C:\Program Files\Adobe\Reader 11.0\Reader’ and this process shortens the time needed to start reader by preloading its components.
You can’t disable or delete this file, if you delete it, Windows configures Adobe Reader and that file gets added to the Reader folder mentioned above when you launch the Reader. So forget about disabling reader_sl.exe, it also doesn’t hog system resources.
Without AdobeARM.exe process Adobe Reader can function, if you think this process is consuming your valuable system resources, then here is how you can disable it.
1. Open Adobe Reader and from Edit menu, select ‘Preferences’ (Ctrl +K)
2. Once the Preferences panel opens, select ‘Updater’ tab and select ‘Do not download or install updates automatically’, which by default set to ‘automatically install updates’.
3. Click ‘OK’ to apply the changes.
