As for your updated Windows 10 operating system from 8 (or 7) since, Microsoft stores your CPU data in their database you don't need the license key anymore. You can download CCleaner, install it and open it.Ĭlick to Registry then Scan for Issues and Fix Selected Issues This should fix your problem but if you want to take more additional step to make sure you are free from other registries as well. Then, download device cleanup tool to remove non-present drivers from your system. It also helps you to remove registry of related application. I suggest you to download trial license of Revo Uninstaller Pro and install it.Īfter the installation open the application and click on Force Uninstall type the name of the program/registry or leftover application name to force uninstall it. The last thing I can think of right now that I didn't try is "format C:" but before nuking my system drive I'd like to be sure there's really no other option, especially since I'm not sure how I'll be able to reinstall windows after that given my copy is an update from 8 that was updated from pre-installed 7 so I don't have any license key anywhere. BTW it's wasn't the only driver left-over after the procedure. Use Windows 10 Fresh Start function! wacompen.sys and the registry keys are still there after my system was supposedly reset to factory default, and no the Bamboo didn't come with my computer.Try again after restarting in Diagnostic Mode, still no success.Manually delete the registry keys without any success (I get error messages).Manually remove wacompen.sys using explorer and administrative PowerShell without any success (I get an error message telling me I need authorization from TrustedInstaller to proceed).


Uninstall the device in device manager.The uninstaller exited with an error telling me the applications was already uninstalled which I knew was wrong. Run uninstall from the applications settings page of course.I've already searched the net for possible solutions and tried the following : I've read having multiple tablet drivers can cause issues so I tried removing the Wacom drivers but so far I've been unable to completely remove the stubborn thing no matter what I tried. I recently bought a pen tablet to replace an old Wacom Bamboo that wasn't working correctly anymore.
