Usage logs are not being deleted (SharePoint)

We've ran into an issue recently, where the *.usage logs were filling up the partitition and not being deleted. This usually happens when the SharePoint Timer Service locks up and is not freeing those logs. To fix this problem, stop the SharePoint Timer Service. Sharepoint will then delete the logs by itself (immediately).

If that does not happen, you can delete them yourself. The logs are located here:

Postfix drop a particular email

Prevent programs from starting automatically on boot

There are many instances when programs are starting when the computer boots, bring annoying pop-ups and consuming resources. Most of them have a way to disable that feature, some of the more poorly designed ones do not. There's a way to disable it, using an configuration application called msconfig. It exists in all modern Windows versions:

windows start msconfig

Go to Startup Tab and uncheck any application you don’t want to launch during boot time. Click Apply and then OK.
