mdt - Microsoft Deployment Toolkit setting SystemAutoLogon registry key when deploying upgraded OS -


i'm trying deploy images via mdt have been upgraded via mdt "standard client upgrade" task sequence. images started win10 v1607 images , updated v1703 , captured.

when go deploy captured images, i'll popup on first login c:\ltibootstrap.vbs can't found. digging, discovered after os installed , pc restarts, mdt task sequence continues running the system account . bizarre typically runs built-in administrator account.

for reason, though unattend.xml file contains usual autoadminlogon entries, registry key at

hklm\software\microsoft\windows nt\currentversion\winlogon\systemautologon

is being created , set 1 during deployment. (i discovered comparing registries @ end of deployment.) key not present in captured image. this key not created if deploy image manually updated v1703 (via windows update instead of mdt).

any ideas on why unattend.xml ignored or cause systemautologon created , set?

i figured out going on.

the mdt upgrade task sequence invokes upgrade command line /postoobe option pointing setupcomplete.cmd. causes file copied c:\windows\setup\scripts\setupcomplete.cmd. when windows install complete, if file present @ location, run under system account.

the problem file remains after upgrade task sequence totally complete. if capture image , deploy real machine, see setupcomplete.cmd , run after deploy, instead of using usual default administrator account.

i imagine presence of file @ c:\windows... causes registry changes mentioned above. setupcomplete.cmd built bootstrap upgrade mdt task sequence, , needs removed c:\windows... when task sequence done running.

knowing post-upgrade portion of upgrade task-sequence runs system instead of administrator via different mechanism standard deployment important, there limits can do. default sequence lets install applications.. need apps ok being installed system.

for i've updated local setupcomplete.cmd in scripts directory delete when done changing last loop (there typo in loop before preventing exit echo):

for %%d in (c d e f g h j k l m n o p q r s t u v w x y z) if exist %%d:\windows\setup\scripts\setupcomplete.cmd (  del /q /f %%d:\windows\setup\scripts\setupcomplete.cmd echo %date%-%time% exiting setupcomplete.cmd >> %windir%\temp\setupcomplete.log)

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
