I have over 9Gb of files in the c:\windows\installer\ directory. These files are all .msi or .msp and have names like 2daa70f.msp, 2daa71b.msp and 2daa71f.msp.
Many of the files seem to be duplicates (same size and date). Eg: 126 files from 7/72004 that are all 26,690,560 bytes.
Can I delete all these files?
There are also 186 folders in c:\windows\ all named like: $NtUninstallKB901214$ or $NtUninstallQ329441$. These only take up 284 Mb, but it just seems like clutter to me. Can these also be deleted?
