Route.exe error on shutdown.

When I shutdown I frequently see an error flash quickly on the shutdown screen telling me (I think) that route.exe cannot start. What causes this and how can I fix it?

Thanks Ken. Yes, I had done searches here and elsewhere and found references but nothing definitive.

It has been happening for a while and has been more of an annoyance than something that is having an effect on the sysytem and just today I thought I would try to do something about it. That being the case using restore points is unlikely to be effective.

I do use a registry cleaner from time to time. It has always been the same one and there hasn't been a recent update that could have changed things.

Thanks for the clean boot link, I'll se if that can help.

Skip the registry cleaner.
Cleaning is for dirty carpets, and dirty clothing.
Registries do not need cleaning.

Ask yourself how many of the billion Windows users have a registry cleaner. (Approx. 0%, rounded to three decimals.)
Ask yourself why those billion non-users of registry cleaners don't have problems.
Then ask yourself why you'd need one.

Thanks both. I've used a RC for more than 20 years but I will cease that now. The repair sounds a way forward Ken, thanks for the link.

I have done an 'in place upgrade'. It has not only fixed that problem but solved a couple of other oddities that I had noticed recently. Quite painless and everything that should be still seems to be in place.

Thanks Ken and also my thanks to the team who put together the tutorial. I don't know what I would do without you all!
