How to directly integrate a hotfix?

[heffalump]

Can someone show a guide or tutorial that is step by step how to directly integrate a hotfix to a source? Like nLite and HFSLIP do? I've been looking at the hfslip file but can't quite figure it out. By direct integration I mean extracting it and then updating correct files and not by using the svcpack and /integrate method? Manually integrating, not using third party tool (apart from normal Microsoft one to compress etc.) Thanks in advance

Very generally,

1. get the hotfix

2. extract the contents using the /X switch

3. find a file or files in the extracted hotfix that match Windows system file(s)

4. rename it to have the same name as the file it's replacing (i.e. if it ends in .EXE and it's match is .EX_, rename it that way)

5. drag - drop - replace into I386

6. done

At step 4, you can also compress the file, which will rename it automatically.
