So far 14316 looks decent .
Contrary to decades old conventional Wisdom and good arguments to this day of clean installing widows (every time ) I just rolled in 14316 over 14295 out of WU today like I been doing since shortly after RTM 10240 and mostly clean installs prior to that.
I havent done anthing significant beyond popping up here on Ten Forums in 14316 (its only been running for some minutes )
I can't attribute any performance problems/improvements or any negative consequences either way from these update/overwrite installs vs clean installs since 10240 RTM or before that unless it was resolving a specific problem or a few of them like it did prior to 10240 RTM .
ofc. YMMV it's Windows after all .
I always roll out a fresh ESD copy from the new build WU downloads first thing and stash it in a named folder in case I need to make an ISO.
I had to use those via mounting them from within windows twice recently when the install set up stalled at checking updates . I by passed all that on the ISO you don't get that option on a direct WU re start/overwrite update install like I did today .
OTOH today's WU overwrite install was as smooth as a new u know what and fairly quick .
I had to roll back a couple of Insider builds until the next one since 10240 RTM (I was tempted on some others ) and also to clean install on those but new builds rolled in ~ soon enough anyway
ofc.like anybody that been around Windows for a while I was very tempted to try clean installs on some of the builds that mis behaved since 10240 RTM and for all I know that might have fixed all that anyway.
I wont knock anyone for preferring a clean install I been using windows long enough to know better since Win 3.1 and DOS to be exact .
There is a new WD notification Icon in the task bar notification area that's fine with me I'm on a 27" and 4K 55" second screen here on this box anyway .
All the basic search bar/task bar /start menu ,Chrome Browser and Windows run tume apps ,mail client and desktop seem fine along with desktop,task bar and start menu tile positions (this time) .
Some of my previously *(always slow to load on any OS )* x86 .exe desktop programs are loading significantly faster now some virtually instantly and on a metal hdd no less . I always check that with a new build just because and this is the first time I've seen any significant improvement . We'll see if all that holds up on those specific x86.exe programs and the others stay tuned .
I'm thinking maybe they did some more code optimization and maybe HDD and physical memory compression and or memory caching improvements to the motor .
I'm thinking of running Pass-mark x64 memory & hdd I/O throughput benchmarks and comparing those results to prior Insider builds & (Prior Windows 7 x64 results ) all on the same NTFS hdd and configuration .
FWIW these specific benchmarks have been unfailingly and significantly slower on Windows 10 and *all the test builds* than win 7 x64 sp1 since I started keeping data in ~late Jan 2015 or specifically (9926 ) or whatever it was ...*maybe something has changed today * stay tuned .
OTOH I'm going to be busy for the next week or so with the EA & bansters and maybe managed fund folks looking for some signigficant large in 2015 tax remediation strategy or deferred tax diversified investment this year it's criminal what they do to some of us for making a buck or some decent cap gains or whatever
