Recently I’ve needed to connect to a virtual desktop using VMware Horizon Client. Immediately after connecting, I received the error message:
ERROR (1FD0-19D0) <6608> [vmware-remotemks] HccChannelPlugin::ChannelAddRef: No shared memory channel. Horizon client service may be down.
FATAL (1FD0-1E14) <vmware-usbd> [vmware-remotemks] GOT DEP ACCESS VIOLATION
After much research and try & error, I was able to determine that VMWare Horizon Client requires up to 4GB of RAM for physical machines and 5GB of RAM for virtualized Windows 7, 8.1, 10 systems (VirtualBox, VMWare Workstation).
If you receive the error message 0xC004c780 when activating a Microsoft product, just wait a few hours. The error message typically means the activation servers at Microsoft are temporarily overloaded. This occurred most recently during the Windows 10 Anniversary Update weekend (8/14/2016)
I have a Toshiba laptop running Microsoft Windows 10. I’ve recently reinstalled the operating system and noticed that the touch screen stopped working. I searched high and low looking for an answer but didn’t find one that would work.
Microsoft recommends the following but it didn’t help me:
- Re-start your PC.
- Wipe it off. Use a microfiber cloth if possible.
- Search Calibrate the screen for pen or touch input from the task bar and select the top result. Hit the Setup button and follow the prompts.
- Search Device manager from the task bar and select the top result. Select Monitors and right click on the name of your monitor. If one of the menu items is enable, choose that.
- Repeat process number four above, but this time choose Update driver software from the right-click menu.
It was, however, quite close to what I discovered was the problem. If I went into Device Manager (Windows Key + X and choose Device Manager) and Disabled/Enabled the HID-compliant touch screen device the touch screen would work for a few minutes and then suddenly stop working again.
After scratching my thinning hair on top of my head, it dawned on me that it was probably power management related. I looked in the Power Management tab for the device but the option was disabled.
So what to look at next? All of the Human Interface Devices run as USB devices.
Looking at the Universal Serial Bus Controllers I saw that several of the USB Hubs and such did have the Allow the computer to turn off this device to save power option set.
I unchecked the option and disabled/enabled the HID-compliant touch screen device and Voila! the touch screen worked! It’s been several hours now and the touch screen is still working fine.
