Hello I recently after a windows update I noticed a error in the event viewer 4107 CAPI2 failed extract of third party root list from auto update cab at <http//www. download windows update .com/MS download/update/v3/static/trusted/en/authrootsti. cab>with error : A required certificate is not within its validity period when verifying against the current system clock or time stamp in the signed file. I haven't been able to find much on this issue but I tried running the link in the error log but didn't fix. Anyway does anyone have a solution or even some info also my laptop has same error wierd. I think win update caused issue but I also did a restore back about a week ago maybe this is problem. One more thing is there somewhere I need to place the file that is linked in the error somewhere after install?THANKS FOR ANY HELP!
