I can't update Windows Security Essentials get error code 0x800A0046,and my Windows Update isn't working either and get code 0x80070005. I have tried for the last two weeks to fix these error using various Microsoft support programs and various other programs I found on the net. I  ran sfc.exe but nothing has worked. All was working until I started my computer up the next day and then these problems occurred. I know what the error code means but can't find a SIMPLE or even a fix for these error codes. I ran Troubleshooting on windows update and it noted all was OK but when I went into details I notice something weird:   it said "Troubleshooting problem preventing windows update" I really don't know what this means or if it is even relevant. When I tried to update Windows Security Essentials I also get the same error code I get for windows update 0x80070005. I have tried System Restore but the problems remain. I don't know what has caused the updating problems blmeut they are starting to affect some other programs that require updating. I really need a simple explanation of why this happened and a SIMPLE set of instructions if someone knows how to repair these problems because I am not that computer literate. I don't have a reinstall disk either.


I am using Acer notebook with windows professional 64 bit with internet explorer 11. Thanks and I hope someone knows how to repair these errors.

Will there be daily updates for windows security essentials after April 2014 for windows XP?
Will windows security essentials still work after April 2014 on a computer running XP?
Thanks
