thank you from down under.
I ran the tasks you had asked and not sure what I am doing wrong. But I took a screen snip to show the different ways I tried to run the command, get-computer....
Some pertinent facts. this is my son's laptop. The embarrassing fact is the last successful update was 7/26/14 Microsoft Silverlight. The time and date of the computer was not correct when I first tried to update recently. I corrected it.... We are using windows defender, and Ccleaner. we do have backups to the registry.
Thank you again for your efforts, Sorry I didn't post more quickly but we are vacationing in Maine. Lobster feast tonight!!!
