I'm running Windows Vista Home Premium with Service Pack 2.
I have 15 "Important" Windows Updates that won't install: 9 security updates, 3 windows updates for Vista, etc. One dates back to 12/8/09 and the most recent 4/13/10. They're starting to add up.
When I try to install them, some will fail due to a 8007371C error and the rest will say pending (until restart), but then after the restart they fail to install (but no error code).
I've tried installing them with UAC, anti-virus, and firewall off, but the result is the same.
When I try to install any of them in safe mode, I get "Installer encountered an error: 0x8007043c. This service cannot be started in safe mode."
I scanned the hard disc for errors (i.e., check disc) and found none. I've scanned for viruses, trojans, and malware and have none.
I tried installing the System Update Readiness Tool for Windows Vista (KB947821) [January 2010] (with UAC, AV, etc. off) but the installation "failed" (no error code). Installing it in safe mode gives me the "... 0x8007043c. This service cannot be started in safe mode."
