Searched the internet loads, But nothing has helped so I'm trying here.
I need to uninstall SP2 to do a repair install of Vista, Although nothing I can find will uninstall it.
Its not listed in the Add/Remove programs, Even though it says it should be (KBKB948465) And also the command prompt method doesn't work. I get upto Method 3-Step 4 and then nothing happens.
Your best option to repair is to use a Vista dvd with SP2 (the same version as yours)or create one by slipstreaming SP2 onto it.
For detail on repairing and slipstreaming go to: http://www.vistax64.com/tutorials/ [...] vista.html while this refers to SP1 and is out of date, the same principles apply.
