Grits if it was my computer I wouldn't be messing with the registry for such a problem.
My suggestion is; if you are not having problems just keep Windows 7 updated as recommend by Microsoft.
The only updates I research before installing are drivers
and anything to do with Bing.
I install all important and recommended Windows 7 Updates.
I check for Windows 7 Updates a couple times a day. If Microsoft has made a mistake with a previous Update they will correct it and recommend a new Update.
Today I took all Updates, 24 of them and things are working well.
If for any reason you decide to change anything in the registry please ask for help here. A very small mistake can cause huge problems.
