Cumulative updates for windows 1607 should be installed only once in a while. On a SSD, it takes 30 minutes to install and then 30-60 mins for `getting windows ready, dont turn off off your computer'. Basically, you are locked out when it is getting ready. Imagine doing this for 2 times a month. As to the latest and greatest 1703, frequently icons and taskbar do not load on startup. This happens 1 out of 3 times. Sign out/sign in does solve it. This happens on all my systems (all are 2016-17).
It does take a while to install but an hour sounds excessive particularly for a SSD which should be far faster than a traditional HDD though each system is unique so no doubt some take far longer to update and some are faster with this whole process. Entire installation is over in about an hour total and the main time of that is the initial download and install phase, opening up that express cab file showed some 28000 files in the latest CU so no wonder it takes time for the OS to process all that but the reboot and then going up to 100% completion is pretty quick here. Though it does take a little while for the DISM command to clean up the leftover data afterwards too but that step is optional, deletion of old files is faster but compression is safer if the update ever needs to be uninstalled or reverted. EDIT: Being cumulative updates I assume it's going to be the same for RS3's update system with the first few possibly going pretty fast and then as more files are built up and modified the later updates will start seeing longer install times due to the sheer amount of files that are updated.
I am running LTSB 2016 as well on a laptop with SSD (Samsung SSD 840 Pro). I am installing every cumulative update as it is being released. This takes 5 to 10 minutes at the MOST each and every time. No joke! I also run a few more computers with 15063 and I can absolutely confirm the desktop issues with the disappearing icons (or not appearing at all after boot and it´s randomly happening here too). Additionally, the "Save As" / "Open" dialog (regardless which program) was randomly not working either in 15063 for me. Those are the reasons I´ve upgraded them to 16299.15 already today and so far, no more disappearing desktop icons and menus
I got KB4023057 some days ago on my 1607. Anyone know what it is?? It install something named remsh.exe
KB4023057 = remsh = Remediation Shell msi package remedy "fix" update related components to allow the upgrade i.e. registry settings, services status, USO and WU SIH schedule tasks, disk space, launch Windows10UpgraderApp.exe if installed (included with 14393 CU)
Thank you abbodi1406 for clearing this up! Of course, I thought it was something suspicious and nefarious that MS was doing. But I was wrong.. Sorry to all for my incorrect assumption and thanks to abbodi1406 for clearing things up quickly.
I also noted that in 1 hour of using 16299.15 but surely 1 hr is not enough to know for sure. How long have you tested. Missing icons is a pain and a loss of time. When the welcome screen shows longer than usual, I know that icons will be missing. I use 1607 only because the overall whiteness of background is much better than in 1703 or 1511. RTM had a good white background and so has 1607. 1703 is a bit towards warm white. 1709 has introduced one small issue: desktop icons are wider horizontally. So if you have 100s of folders in documents, it can add up to 1 more column.
