Inadvertently I hit something that brought up a Uniblue program that altered my registry I believe. I can't eliminate it unless I pay their subscription, cannot delete program. Ever since then I am denied access to a wide range of programs. Just tried to get into System to make sure system restore is on, because it's not working, and am "denied access from several other key programs. Last message on screen read "Error loading C:\WINDOWS\system32\shell.32.dll Acess is denied This happens to several other sites as well. Desperate to sort system out, have no end of recovery programs but don't know which to use if any. Thank you all in advance Muergo, I am rcovering from a hospital stay but now need help for PC, apologise for not replying to earlier topics but haven't been here.
