#1 is also available for Windows file shares since Windows 2003 SP1. Microsoft calls this feature "Access based enumeration".

I also hate it when Settings are moved around in the Control Panel and Administrative Tools. If you often have to access several specific settings, it might be worth to learn the filename of the MMC-SnapIn or Control Panel applet you want to use. For example: Device Manager is "devmgmt.msc", Computer Management is "compmgmt.msc", Network Connections is "ncpa.cpl" - which I find way more convenient if you have to configre network settings in a corporate Environment with different Windows versions.
I don't know about the US, but in Europe PayPal's User Agreement says that it is "licensed as a Luxembourg credit institution". Also I don't really get where all the hate for PayPal comes from.
Yes I read a dozen times that they froze the account of SomethingAwful or some loud-mouthed bloggers under dubious circumstances, but for me it always worked just fine. Actually I really like PayPal because it allows me to send a seller money that is instantly credited to his account, without trust issues on either side or credit card processing for the seller.
I also like the security of going to PayPal's site so I can verify the payment, which is why I am quite sceptical of this API change. But apart from that I really don't see how PayPal is bad in any way for me as an ordinary customer.
