Can someone please tell me how to repair BITS on my W7 SP1 system?
 My symptom for needing to do so:
 When trying to run Windows update, assume I have 21 to install.
 I run WU on 1 selected update, and it runs successfully.
 If I go back to try 1 more, the update gets in what seems to be an infinite loop.
 One of the svchost.exe's (the host process for windows services) uses up to 99% of my cpu.
 With taskmgr, if I kill that process I get an 800706BE error.
 I have run the M'soft fixit to fix WU and Bits. No joy.
 I have run the tweaking.com tool to fix windows, including the step to fix wu.
 When I reboot, I can do 1 install, and then the same thing happens as described above when I try to do another update.
 Any help would be much appreciated.
