I know the process described by aviv00 and I've tested and for me run well. Vlite remove the sxs cache ( obviously not completely but ) well. But the problem of update remain ,perhaps for the damage of the damaged catalog that is not coherent with the file contained in the sxs folder.
I do not understand? Are you saying:
1) VLite works well = removes most of SXS but you can still update normally?
2) RT Seven Lite - Beta build 1.0.9 does NOT
remove the SXS well; RE7lite breaks updates?
Seem to be a good idea marking (example in red) the item's that are delicate to remove and might be some problem without those.
! I loved the old X-Setup for that very reason; it gave a good enough explanation & warning to help you make decisions on what in your OS to tweak. I would like to help out here, but I'm not a sys admin expert enough to really be much use. :/ I really only want to set up my computer once very well & be done with it.
