Microsoft are the creators of the Blue Screen of Death, but we ought to be able to expect basic keyboard functionality from their operating systems, shouldn't we? Modifier keys sticking in Windows 8 (and other maladies)

As a long-time user of Microsoft operating systems, I've done my fair share of troubleshooting. But a problem cropped up early last year in Windows 8 that's been impossible to solve (though it was quiet for much of 2013). Searches show that it's been plaguing users running other versions of Windows as far back as 2006. Even the new Surface tablets are not immune.

Without warning or any discernable trigger, one or more modifier keys stick virtually. They're not sticking physically; the keyboard is clean and the keys work fine normally. (And yes, Sticky Keys are disabled.)

Often only restarting Explorer, singing out, or restarting will correct the issue.

(I've also experienced certain keys not working -- usually C, V, and H -- unless Shift is held down. Normally when this occurs, they'll work in some programs (like Notepad) but not in others (Firefox, Chrome, or the Metro Start screen).)

I've tried a variety of suggestions. Nothing's worked, not even a Repair Install for the tyrannical and broken Update 1. And Microsoft's support is worthless. Last night, one tech never appeared before transferring me to someone else. That tech seemed unable or unwilling to address the issue. And when I finally found someone competent, the Send button in the chat window stopped working, so I couldn't communicate with him.

Microsoft are the creators of the Blue Screen of Death, but we ought to be able to expect basic keyboard functionality in their operating systems, shouldn't we?

(Perhaps someone can let Satya Nadella know so that he can put an engineer or two on fixing this. And the fact that Windows Updates sometimes refuse to install if you've modified your Start Menu folders. Yes, the Start Menu that doesn't officially exist in Windows 8.)

Below is a complete listing of every workaround I've attempted (with observations; failures are crossed out) for keys sticking virtually in Windows 8 and 8.1 over the last one and one-half years:
Clean install of Windows 8.1: System ran cleanly for a week. Installed Java (for LibreOffice) and PowerDVD, played some of a movie file, quit, and the Windows key locked (though it wasn't visible on either touch keyboard). Right Windows key?

Coming out of sleep, Windows key was stuck. Opened G700 Logitech Gaming Software to see if key assignments had disappeared again. Started recording a MultiKey Macro and found that the right Windows key was stuck. This keyboard has no right Windows key.

After a few Lock Screens, the right Windows key released.

Then, C, V, and H stopped working in Chrome without the Shift key, and unable to search in Start screen.

Someone suggested that Chrome waiting to install an update was the problem, but this install was up-to-date.

Checked Windows Update; several are waiting to be installed.

(Get keyboard with right Windows key?)

Used KeyTweak to remap RWin to RCtrl. Windows also updated.

So far, so good ....

Uninstalled iTunes, Bonjour, Apple Software ....

Uninstalled Unity Web Player ....

Remove SetPoint, use X-Mouse

Disabled T650's SetPoint Zoom in and out

Press the right Windows key (None on this keyboard, so I can't try it.)

The malfunctions seem to occur often with Windows and Flash updates and/or YouTube videos (whether Firefox or Chrome).

Disable Microsoft Input Configuration Device

Keep keyboard in front of receiver (not blocked by television

Disable "Turn on Toggle Keys" and "Turn on Toggle Keys by holding down the NUM LOCK key for 5 seconds."

Unplug USB mouse (Event Viewer reporting angle errors)

Remove all keyboards from Device Manager, reboot

Pressing Ctrl and +

Press any Function key

Uninstall Logitech drivers and software; use X-Mouse

End jusched.exe in Task Manager

Moved DiNovo Edge USB receiver from USB hub to motherboard USB port

Removed T650 USB receiver

Disabled Touch Keyboard and Handwriting Panel Service

Killed Origin

Tapped Shift and Alt

Update of English Input Personalization Dictionary causing sticking?

Don't use Windows Magnifier

Uninstalled Classic Shell, ModernMix, and SkyShellEx.

Okay, so that didn't work. Alarms is gone, and still the keys locked. It was after a long time, and I got a low memory warning. Chrome was running along with iTunes, Origin, and Magnifier.

Pressing keys on physical and virtual keyboards -- and switching virtual keyboards -- seems to have worked ... temporarily.

PowerDVD, USB device, Logitech or Touch processes

Killing BZTRANSMIT64.EXE or BONJOUR released Win key. (Then it reappeared stuck in Touch Keyboard -- but not physically -- until switching to another Touch Keyboard)

Killing Bonjour, some Logitech processes, and turning the keyboard on and off made a difference (this time).

A pointer device did not report a valid unit of angular measurement?

A pointer device has no information about the monitor it is attached to?

A multi-touch device reported inconsistent contact information?

USB issue failing to load drivers?

VLC? Windows Update? Bztransmit64.exe? (overloaded system?)

Disable Intel xHCI mode (?) Enabled USB Legacy Support. Disabling Fast Boot in BIOS not an option with current motherboard; perhaps powering off computer completely (in order to access BIOS; did it clear a conflict Windows 8.1 was saving from restart to restart?) and/or enabling USB Legacy Support might have solved (?) the problem.

Disabled Sleep

Removed unknown from Control Panel\All Control Panel Items\Language\Language options\Input Method

Uninstalled VirtualBox

Tap Win (Ctrl, Shift, Alt, hardware and virtual) several times

Detached G700 and T650 TouchPad

Removed Logitech extensions from Firefox, Chrome, and IE. Both browsers have been running for hours. The computer's entered and exited sleep several times.

Uninstalled Zune, iMon

After a Windows Update, no problems for a couple of days. (2/17/13)

https://support.mozilla.org/en-US/questions/948889

Uninstalled WizMouse

Uninstalled Firefox

Uninstalled and removed all traces of Logitech software (except Harmony); old versions conflicting? IE and Firefox extensions conflicting?
