My desktop icons won't open because the drop-down-menu headed with the word "OPEN" has vanished.

Can you help please because I have been trying in vain for hours to solve the problem.

Thank you in advance.

I don't know, but it would be worth periodically running clean-up applications if you have them. First and mostly recommended utility is the free version of CCleaner to run perhaps monthly or every second month (ignore the buy version, that's a type of donation & also for specialist purposes.) Once in a while, select the Registry section to do a scan & fix issues, but do the recommended backup just in case something misbehaves as a result of cleaning up your registry.

And perhaps Defraggler for defragmenting your drives.
