problem about "Hotfix uninstallers" option

[luweitest]

I am on windows xpsp3, and had used "Hotfix uninstallers" cleaning feature before. Recently I did some system update, then used the new CCleaner, but the "Hotfix uninstallers" option is gone. I reverted to version 5.46 and found the option again.

And after done the cleaning with ccleaner 5.46, I found that there are still those directories under \windows:

$968930Uinstall_KB968930$ (strange name, with only two files in it: PSCustomSetupUtil.exe, PSSetupNativeUtils.exe)
$NtUninstallMSCompPackV1$
$NtUninstallWdf01009$
$NtUninstallwinusb0200$
$NtUninstallWMFDist11$
$NtUninstallwmp11$
$NtUninstallWudf01000$
$NtUninstallWudf01009$
$NtUninstallXPSEPSCLP$

I wonder whether they belong to "Hotfix uninstallers" or not.
