I've got a folder with the name $hf_mig$ which contains 40 folders that are each named KB(followed by 6 digits).

I've already deleted all the $NtUninstallKB123456$ folders and the KB123456.log files from C:\WINDOWS, and have also deleted all the Windows XP hotfix entries from Add/Remove Programs.

Is this folder safe to delete?:confused:

I wouldn't - basically you can then be installing older versions of the same file with a new hotfix that gets applied.

Read here - Ripped directly from the MS site.

When a security update, critical update, update, update rollup, driver, or feature pack installs GDR version files, the hotfix files are also copied to the %windir%\$hf_mig$ folder. This supports migration to the appropriate files if you later install a hotfix or service pack that includes earlier versions of these files. For example, consider the following scenario: 1. You apply a security update that installs a GDR version of File.dll with a version number of 5.2.3790.1000 and copies a hotfix version of File.dll with a version number of 5.2.3790.1000 to the %windir%\$hf_mig$ folder.
2. You apply a hotfix that includes a hotfix version of File.dll with a version number of 5.2.3790.0000.
In this scenario the hotfix installation in step 2 installs the hotfix version of File.dll (version number 5.2.3790.1000) from the %windir%\$hf_mig$ folder instead of the hotfix version of File.dll (version number 5.2.3790.0000) from the hotfix package.

Thanks for the quick reply. I was just curious about it. I'll leave it alone.
