DISCLAIMER: THIS WORKED FOR ME BUT MIGHT NOT WORK FOR YOU. BACK UP YOUR DATA.
I run a Lenovo T400 ThinkPad with Windows 7 Professional. I have been using Acronis to perform image and file backups. Following a hard drive crash (of a 500 MB Western Digital drive), I put in a brand new 500 MB Western Digital drive and managed to do an image restore and file restore.
After slogging through various bugs (which I am too bleary-eyed to recall), I kept hitting two vexing problems:
1. Windows wouldn't update. I'd get an error message saying that "Windows Update cannot currently check for updates because the update service is not running," and
2. From time to time, Windows was convinced that somehow I wasn't running an authentic version of windows, even though the "it's authentic!" seal appeared in My Computer: Properties.
I followed the advice on this Microsoft forum http://answers.microsoft.com/en-us/windows/forum/windows_7-windows_update/error-code-0xc8000247-cant-install-updates/198166df-9549-e011-8dfc-68b599b31bf5?page=2
which suggested I go to this particular-language HP driver site to download something called "Intel Rapid Storage Technology" to fix an issue with users of Western Digital Drives: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c02219204&lc=en&cc=uk&destPage=document&dlc=en&product=
What didn't work (or, rather, what didn't seem to help)?
- Installing a ton of Lenovo ThinkVantage updates (actually this seemed only to cause a new problem related to an ATI video driver)
- Turning off the update service, deleting the contents of a particular Windows folder, and restarting the update service
- Generally freaking out at 11 pm
Anyway, I hope Google finds this post so that more Western Digital / Acronis customers find the solution.
