I'm just sick of this neverending story of M$ WU bugfixing w/o any result...
Thus pls find a closing comment to the M$ Black Tuesday of May 2015 and my personal conclusion concerning this M$ mess. I guess that now it's really the final one.
IE11 patch KB3021952 (Feb2015) as the early bird of this year M$ WU issues as well as the sole problem remains unsolved by MS WU team thru 3 months is put to a hidden list in its full size of 55MB forever. There is no any limitation for deepclean at the
moment.
The funniest point of all this fuss around is that its sole culprit is KB3023607 (some messy TLS security patch aka Windows6.1-KB3023607-x64.msu), which was very much unlucky bundled by the M$ WU team to KB3021952 aka IE11-Windows6.1-KB3021952-x64.msu and
offered as a single update KB3021952.
If M$ WU team could be smart enough to simply unbundle this combined KB3021952 and offer both its parts separately we'd likely have no problem with updating of IE11 itself but just a cycle re-offer (after deepclean) of some standalone small & likely non-critical
TSL patch aka KB3023607. I believe this TLS patch as non-critical when my IE11 always passes M$ own TLS test here
M$ TLS Test Page either with or without all these IE11 security patches offered from Feb2015 installed.
Moreover, I found that every IE11 update offered earlier and put to a hidden list is vanishing from WU every time when any next IE11 patch offered, therefore it seems very much likely that if IE11-Windows6.1-KB3021952-x64.msu would offered separately it
will be smoothly overwritten by any of the next offered IE11 patches and thus isn't essential to be installed when any next IE11 patch is applied.
Well, now there are 5 KBs total in my hidden list:
- KB3021952 for IE11 of Feb2015 in full;
(Note: Both KBs for IE11 of Mar & Apr 2015 as KB3032359 & KB3038314 were simply vanished from my WU hidden list immediately as the new IE11 patch of May2015 aka KB3049563 was offered & installed)
- two KBs first marked by WU as Optional and now as Recommended - concerning the Win7 upgrading as KB2952664 & KB3035583;
- two others first marked by WU as Optional and now as Recommended - those are
likely useless in my case:
KB3013531 - it's some trash about .mkv media files transfer to Windows Phone...
(well I don't have any objection to use of .mkv files... although it's surely the greatest sorrow of my life that I don't see any winphone around. hey winphone where are you?!)
KB3022345 - it's some Diagnostics Tracking Service of Win10...
(oops I believe that it's better to stay away from M$ support, which is overcrowded by m$mvps... anyhow I'm surely don't need one more tracking service of M$... at least until it will be proven as helpful)

Have a fun!
