Remove and Disable Win 10 PIN for Work/School Account I have found lots of ways to remove the PIN logging from the Windows 10 Windows Hello service but they all apply to a non work/school login account. My account is a work account and when I want to remove the PIN the remove button is greyed out. How can I re-enable that button so I can remove then pin then disable Windows Hello on this machine?
Can't disable windows 10 PIN complexity I recently linked my Microsoft Office account to my school to have access to Office for students. Right after linking my account, I couldn't login to my computer again with my 4-digit pin code and got the message: "your organization has set the following pin code requirements. Your pincode has to be at least 6 digits long."   I had to change my pincode but I want to change it back to my original 4-digit one. Some internet research has made me enable gpedit.msc, but when I try to find the PIN complexity setting in gpedit (Computer Configuration\Administrative Templates\System\PIN Complexity) it just isnt't there.   Another possible path in gpedit I found on the internet to do this was: Computer Configuration > Administrative Templates > Windows Components > Windows Hello for Business > PIN Complexity, but that also didn't work as I don't have "Windows Hello for Business"   I also tried resetting my computer to the date before I joined my 'organization', but that didn't work either.   Does anyone have an idea how I can resolve this issue?
Why does the sum of the reciprocals of factorials converge to $e$? I've been asked by some schoolmates why we have $$ \sum_{n=0}^\infty \frac{1}{n!}=e.$$ I couldn't say much besides that the $\Gamma$ function, analytic continuation of the factorial, is defined with an integral involving $e$. Then I also know that actually $$ \sum_{n=0}^\infty \frac{x^n}{n!}=e^x.$$ Is there a reason for these facts?  P.S. I added the tag "intuition", please remove it if you think it is not pertinent. What happened to the "very low quality" flag reason? Possible Duplicate:          I see a  to receive a "very low quality" flag by me.  It's just a link pointing elsewhere basically saying, "try this." I generally do this for answers I see that are like this and have been successful every time so far.  I save "not a real answer" flag for other cases such as someone asking another question in an answer or "thanks" answers.  I want to flag it as "VLQ" but I don't see that as an option*.  In fact, I don't see it as an option anymore on any site throughout the Stack Exchange network.  * This was not possible before when I initially posted this. Michael's observation on the needed downvote seems to be the reason it didn't show up.  Did it just get phased out as being unnecessary?  Should I be using "NARA" as the flag reason for this case now?  I'm not sure if the "NARA" explanation really covers this case well: (emphasis mine)     This was posted as an answer, but it does not answer the question. It should possibly be an edit, a comment, another question, or deleted altogether.   These sorts of answers can answer the question in general.  The site linked to might very well completely answer the question.  (in this particular case, maybe not however)  It's just that the answerer really should do something to improve the answer.  It's not like it's a "This question is a duplicate of this [onsite question] post" or some other general spam.  Those cases are clearly "NARA"/spam.  There was a  regarding the necessity of this flag reason.  Answers point out that it is needed and I agree.  There hasn't been anything mentioned (that I am aware of) in terms of removing it by the team.  Was this officially removed now in favor of other flagging reasons?  Or is this just a bug and it was "accidentally" removed? Split seeds.rb into multiple sections? java.lang.RuntimeException Cannot find FacesContext Recently I've noticed more and more sign-in / sign-up workflows defaulting to the sign-up option first and providing a minimal "Sign-In / Login" action somewhere else on the page. What's the reason behind this practice?  Examples where I've seen this recently: Device not detected in Eclipse when connected with USB cable $\sum x_n^2$ and $\sum y_n^2$ converge, what does $\sum (x_n + y_n)^2$ do? So I know that $\sum x_n^2$ converges, and $\sum y_n^2$ converges. ${x_n}$ and ${y_n}$ are both sequences of real numbers. How can I prove that $$\sum(x_n+y_n)^2$$ converges? So far I have $$\sum(x_n+y_n)^2=\sum(x_n)^2 +\sum (y_n)^2 +\sum(2x_ny_n)$$ so I need to prove that $\sum 2x_ny_n$ converges. Is this the right way to approach it? If it is, I am completely lost as to the next step.  I also need to prove that $$\sqrt{\sum(x_n+y_n)^2}\leq \sqrt{\sum(x_n)^2}+\sqrt{\sum(y_n)^2}$$  I assume this will follow pretty easily from a result in the first proof, but I'm stuck on that now, and perhaps it is easier to start with the second one. I have a lot of work I've done on the first problem, but none of it seemed to go anywhere. Any hints?  Thanks! Lebesgue integral uniform convergence Let $f_n, f \colon [a,b] \to \mathbb{R}.$ Show that, if $f_n \to f$ uniformly, then the Lebesgue integrals are equal, i.e. $\int f = \lim \int f_n$.

C++ namespace and include Why do we need both using namespace and include directives in C++ programs?  For example,   #include &lt;iostream&gt;  using namespace std;  int main() {  cout &lt;&lt; "Hello world"; }   Why is it not enough to just have #include &lt;iostream&gt; or just have using namespace std and get rid of the other?

Is this a capacitor start motor and can I start it with a microwave capacitor I salvaged an old motor out of a air conditioner and I want to know if it's a capacitor start motor if I can start it with the capacitor I have and how to start it.

I'd expect that if I had a command like the following:  username@someserver ~/somepath $ ssh -i /path/to/private/key myusername@something.someserver.com  The command should render on two lines. Instead it will often wrap around and start writing over the top of my prompt, somewhat like this:  myreallylongusername@something.somelongserver.comh -i /path/to/private/key  If I decide to go back and change some argument there's no telling where the cursor will show up, sometimes in the middle of the prompt, but usually on the line above where I'm typing.   Additional fun happens when when I Up to a previous command. I've tried this in both gnome-terminal and terminator and on i3 and Cinnamon. Someone suggested it was my prompt, so here that is:  \[\033[01;32m\]\u:\[\033[01;34m\] \W\033[01;34m \$\[\033[00m\]  Ctrll, reset, and clear all do what they say, but when I type the command back in or Up the same things happens.  I checked and checkwinsize is enabled in bash. This happens on 80x24 and other window sizes.  Is this just something I learn to live with? Is there some piece of magic which I should know? I've settled for just using a really short prompt, but that doesn't fix the issue. Prove the set of all infinite binary sequences is uncountable by using Cantor's theorem.

Black screen after suspend-after moving to the nvidia official drivers (not priority) So, when I used the priority drivers, the suspend worked normal.

The positive/negative energy duality of 3rd edition seems to be gone. Negative energy spells now do necrotic damage; some undead are resistant or immune to necrotic damage, but it isn't listed as healing them. Classic negative energy spells like inflict wounds and harm don't list undead healing as a possible effect.  For zombies and skeletons it might not matter, but liches and vampires would never risk their necks if they didn't have some way to recover hit points. What is it? Layers with same coordinate system should align/overlap in ArcMap but do not?
