What uses this driver?

I was wondering what uses the driver called epm-shd.sys?
I thought it would be the empowering management stuff, but after I removed the program the driver is still there.
I'm asking because windows 64-bit doesnt seem to like it since everytime I start the computer in the system logs is says:

"C:\WINDOWS\SysWow64\drivers\epm-shd.sys has been blocked from loading due to incompatibility with this system."

than the next thing in the log says:

"Acer EPM System Hardware Driver service failed to start"

Thanks in advance

Do you know how I remove it or turn it off? I uninstalled everything in add/remove, but it still tries to start everytime to computer boots up and it causes it to take a long time to start windows, because it tries to start it everytime.

Thanks

Reboot in safe mode and delete the file or move it out of the location it's currently in.

I did that but it still trys to start the service because in the system log it still says:

"Acer EPM System Hardware Driver service failed to start"

this time though it says it can't find the file instead of before where it said the driver failed to start.

Any ideas?

When I installed the program again, it puts the file back in there, but when I uninstall it, it leaves the file in the drivers directory.

Also, when it installs it says that it cannot start the system hardware driver. Which makes sense, but doesnt explain why it still leaves the file there.

Thanks though, any other ideas?

After you uninstalled Acer EPM.

First method.

Right-click on "My Computer" on desktop or in Windows Explorer and select "Manage..." Select "Device Manager" in the tree. In menu click "View"->"Show hidden devices" Expand "Non-Plug and Play Drivers" and select "Acer EPM System Hardware Driver" From menu select "Action"->"Uninstall" (or Disable - that might work too).
You may need to reboot.


Second method.

After you uninstalled it and removed file as recommended in earlier post, reboot as normal, run regedit.exe, navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\
find EpmShd subkey and delete it. If you have problems deleting it, right-click on it, choose Permissions and check Full Control permission for,say, Users, then click OK and you'll be able to delete it this time around.

Thank You, Thank You, Thank You

It was in both those locations and I got rid of both of them and now the system log looks good and my computer starts up a little faster.

Thanks you

It won't prolong any battery life if it does not work (under 64-bit OS), would it? Acer does not have 64-bit versions of its e* utilities. But my guess is they soon will.

Besides, EPM itself did not prolong battery life, it's just a fancy interface to the functions already supported by OS and drivers and a way to manage profiles with a finer degree (like turning off PCCard controller in profile, while you can always do it through the icon "Safely Remove Hardware" in system tray). Use RMClock for real battery life improvement

Duh, I would have thought that something with Enhanced in the name should have better driver, or at least customized to the specific machine.
If all it did was to have some fancier interface for windows' own power mgmt, then ofcoz - get rid of it
