It comes with Drag 'n' Drop CD, it causes cpu spikes, uses up ram, and is useless, definatly remove! also i get adaware notifying me of registrychanges constanty, and to remove: open cmd , change directory by typing "chdir %systemroot%\system32\" press enter, now type "ezsp_px /forceuninstall". done :). beware it is easily infected
Installed by Sony Sonic Stage, file is self-perpetuating. If it is running as an active process it will re-seed HKLM\SW\Easy Systems Japan Ltd.\Setting\ezsppe_enabled =1 and HKLM\SW\MS\WIN\CV\Run. To remove: 1. use task manager to stop service. 2. run reg_edit and delete the key in HKLM\SW\MS\Win\CV\Run\ezsp_px.exe. 3. Again, in regedit, find HKLM\SW\SW\Easy Systems Japan Ltd.\Setting there's a setting called "ezsppe_enable" set this to 0 (hex). Reboot and it will not show up again.
It causes McAfee to not function. I can not get rid of it.
As above, Sony DVD burning process. Uninstall the program - it is junk and can cause all sorts of other problems!

To truly remove it: 1)Boot into Safe Mode (F8). 2)Navigate to the file C:\Windows\System32\EzSP_Px.exe 3)Rename it EzSP_Px.bak. 4)Reboot. It re-occurs due to a registry key that loads the file each time you reboot or start. Doing this creates a brief error msg when Windows attempts to load the (now missing) file and fails. Once you are convinced no true harm is done use cCleaner or Glary Utilities (or other valid registry cleaning tool) to clean your registry. Problem gone. br br Bill Trail br President Penny Computer Systems, Inc. br Macon, GA 31211 478.787.4532 (7/19/2009)

pretty sure it's from sony pc's easy drag and drop maybe sonicstage too. run msconfig to enable or disable start up items. pc runs fine without it, if an app nedds it it will run it by itself :)

Best practices for resolving ezSP_Px issues

A clean and tidy computer is the key requirement for avoiding problems with ezSP_Px. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the ezSP_Px.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
