Despite being very old (most recent version is circa Windows 7 RTM) it is still being bundled with modern programs (eg: TMPGenc products, as of 07/2021). It is incompatible with the Windows 10 Virtualisation-Based Security (VBS) feature. Removal instructions (use Administrator PowerShell v6 or higher, earlier versions will not work): 1. Remove-Service -Name "pxhlpa64" 2. sc.exe delete "pxhlpa64" 3. [reboot the machine] TMPGenc programs will still edit videos, but (probably) will no longer burn optical discs (use other programs for burning instead). But VBS can be engaged and other optical disc applications (such as AnyDVD) may be more stable.

This file was added to my windows 7 C:\Windows\SysWOW64\drivers directory and caused boot failure on restart. The Windows startup repair could not fix it, but I noticed it in the repair log. I mounted the drive in another system and renamed the file to pxhelp20.xxx. And, my Windows 7 64bit could boot up. I installed a few products before encountering the boot error: cyberlink power2go and sony picture motion browser. Not sure which created this bit of crap.

installed with Sony Picture Motion Browser V2.1.00. Killed my Windows 7 machine. I could not reboot nor was the auto fix able to fix anything. The auto fix told me that pxhelp20.sys was corrupt. I renamed the file through the command line and now I can reboot. Not sure yet if I lost any functionality. I tried Gateway technical support first since this was a new computer they told me I had to ship the computer back to a service center to have it fixed. The person or persons who wrote this software should be fired or be requred to pay restitution to all of us who have wasted our time debugging our systems.

Avast! popped up a warning at the end of installing Winamp 5.5.8.2985. I followed the Avast! instructions, rebooted with a full pre-boot virus scan, and came up clean. Started Winamp, it invited me to upgrade to 5.61. Installed 5.61, and I didn't get any warning. Maybe installing 5.61 in the first place would have avoided the problem. PxHelp20.sys still shows in my C:\WINDOWS\system32\drivers folder :(

It's not a virus etc., it's just a stupid problematic and uwanted driver. PxHelp20.sys (ver 3.00.93.0 no digital signature) appeared on my system most probably after installation of DivX Player Plus. At that moment, my DVD drive lost the ability to read/burn/recognize any Verbatim DVD media, TDK DVD+R, and some other. Even some discs burned+verified on my PC few weeks ago are inaccessible now! I canNOT read my own backup! Now, I am able tu burn only on old Sony DVD+/-R. On the other hand, it seems that problem with Kodak CD-R disappeared, not sure due to this driver. I'll uninstall DivXPlayer!

It's creation date and time is the same as most files in Winamp folder (Program Files). It bring "Lower Class Filter" to my DVD burner. Deducing, it supports Winamp burning capabilities. Drive filters change drive's behavior

Best practices for resolving PxHelp20 issues

A clean and tidy computer is the key requirement for avoiding problems with PxHelp20. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic 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 6resmon 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 executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To get your computer running as fast as it did on day one, you can 8reset your PC. Your personal files will remain intact, but any programs you installed will need to be reinstalled.
