Still unable to create a restore point. I contacted Microsoft Support and, after lengthy investigations, he decided to do a complete Windows re-install. That also failed so I was advised to get a new PC (mine is 7 years old). In summary I conclude the Kaspersky error was just a coincidence and the case may be closed. Thanks for trying to help.

Yes, but I got no further than step 2. When I clicked the "Create a restore point link" the error message that I posted popped up so I couldn't progress with it.

I searched for "Create a restore point" - clicked the link that it found but I immediately got a pop-up error message (attached file) and the create a restore window was stuck searching foe available devices

Thanks for replying. Here are my observations to the numbered points you raise: 3. I clicked "Scan for hardware changes" and the display was refreshed but in the same state. 5. I'm afraid I'm not sure how to access the list of "Network Connections" that you refer to. I can open the Control Panel (see attached image) but I cannot locate a list of connections, only a status page (see attached image). When I click on the status of the item with the yellow triangle I see the message "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)" As for the 'unable to sleep' problem I am still investigating (and trying to see other [people's solutions) but it is a bewildering task!

I am investigating why I am suddenly not able to put my PC (running Windows 10) into sleep mode. The sleep and power options seem OK. An Internet search suggested checking for problems via the Device Manager menu and look for devices showing a yellow 'alert triangle' The only one I can see is against "Kaspersky Security Data Escort Adaptor #2". Could this be the culprit? If so, how might I solve it?
