Some additional notes on installing manually and Windows 10 stuff.
If you need to download SleepyHead from the web, at the time I wrote this, only the Singapore link was working. Please select that link to download Beta-2. The others should be fixed shortly.
UPDATE: The Sleepfiles link now works. Thanks SuperSleeper.
To install the Beta-2 SleepyHead update without using the Maintenance Tool, you have to uninstall Beta-1. Previous versions should be fine to keep if you installed them in a different directory than the directory you are trying to install Beta-2.
To uninstall Beta-1, go to Start and search for Add Remove Programs. Click on that. Find Sleepyhead and uninstall it.
If you don't uninstall Sleepyhead Beta-1 and you try to install Beta-2 into the same directory you will get this error:
On the lovely Windows 10...
After I downloaded the SleepyHead beta-2, Windows complained about the download being from an unknown publisher. We see this a lot. Even though I have Windows 10 in Developers mode, it feels I may be too stupid and threw up their Windows Protected your PC blue box.
