update errors 8000FFFF and faliure of update readiness tool vista 32 bit

[AWS]

Recently cannot install various "important" security updates - all repeatedly fail with error code 8000FFFF. Tried fixit but the relevant files do not exist in my registry.

Read that installing KB947821 may help - system update readiness tool for vista. However this does not install. Package initialises and then just sticks on 0 progress. Have left for several hours with no movement. Also tried from a clean boot with no better

result.

I attempted to unistall service pack 2 last night having read this worked for someone, but on startup this morning messages came up saying this had failed and the system was being restored to previous state.

Have installed Malwarebytes but this is finding nothing. Virus scans are also negative (I have AVG)

 

I tried to paste the latest CBS log but it was too long.

 

Any suggestions?
