JSI Tip 2164. SFC /cachesize=xx didn't reduce the size of the cache?

In tip 2076, I described the SFC switches.

When you run:

SFC /cachesize=xx

and restart your computer, the cache (%SystemRoot%\System32\Dllcache) has not been reduced?

SFC /cachesize=xx simply sets the size of the cache. To actually implement your setting, run:

sfc /purgecache

after the reboot.

NOTE: You may need the installation media.
