StickyKeys can't be uninstalled just because of a system crash as the feature is embedded into the Accessibility options
. The worst case scenario is that the feature is disabled from Control panel
and bringing it back is very simple.
I suggest you go to Control Panel > Accessibility options
and check Sticky keys
.
If you don't find the Accessibility options in your Control Panel then open up Notepad and navigate to File > Open
and paste this line: c:\WINDOWS\inf\sysoc.inf
and scroll down under [Components]
and add a new line containing : AccessUtil=ocgen.dll,OcEntry,accessor.inf,,7
then restart your computer and in your Control Panel you'll see Accessibility options from where you can enable StickyKeys
back.
