well, I have just tried it and, ... what can I say, after some due personal adjustment, it works. the free-space gain is about a few hundred megs. I could not take full advantage of the shrinking, owing to my system's apparent need for systemapps, which forced me to place a ! in front of the string concerned. this may be due to the fact that it is a windows11, so I do not know if what I am saying applies to most other ppl's systems. those who know better, pls say anymore.
