windows failed updates with Error Codes 80070643, 80071A91 and 78f

I am having this issue for months now, and i keep getting these errors. I have searched and tried different methods from other forums but only one worked for me, unfortunately just once ( flushing of the software distribution) but after the next day, when my pc was having its automatic update, it gave me the same errors again, and i could not use the method i used the day before. im not a techie person so please help me with light terms if it's ok.. thanks..


i have Windows 7 Ultimate 64 bit, SP1, AV- Microsoft Security Essential, CCleaners, and SuperAntiSpyware Free Edition


i always get error codes 80070643, 80071a91 and 78f, and because of these all 23 important updates always failed..

I have just replied to a post by you with the exact same problem, please just stick to one post at a time or things will get very confusing.

After making a post you should wait at least 24 hours to see if you get a reply, don't forget that the people here are from all over the world so the person who knows the answer may not even be online, so please be patient while waiting for help.

Hi lesley0419, Have a look here Error Code 80070643 - Microsoft Answers this may help also try the system file checker SFC /SCANNOW Command - System File Checker Is your copy of Windows 7 legitimate ,a lot of illegal copies do encounter errors on windows update

hi, yes i ave tried already the FIX IT, but was unsuccessful, i tried also deleting the software distribution, but i was only succesful on it once, the next update, it gave me the same errors again and when i tried doing the same method, it was back again to failures, ive read on some forums about installing the updates on safe mode, but im afraid to do it, as i might accidentally do something stupid on the process..
