systeminfo shows when the system came up after a restart, but does not show when it comes up after a shutdown and then a power on.  For instance when I run this command:  systeminfo | find "Sys"   the output shows:  System Boot Time:          8/10/2018, 8:45:22 AM   Which was when I did a restart.  I tried a solution in the previous question:  Get-WinEvent -LogName Microsoft-Windows-Diagnostics-Performance/Operational | Where { $_.Id -eq 200 }  and got these results on my laptop:   PS C:\Program Files\PowerShell\6.0.0> Get-WinEvent -LogName Microsoft-Windows-Diagnostics-Performance/Operational | Wher e { $_.Id -eq 200 }      ProviderName: Microsoft-Windows-Diagnostics-Performance  TimeCreated                     Id LevelDisplayName Message -----------                     -- ---------------- ------- 7/30/2018 1:54:18 PM           200 Critical         Windows has shutdown: ... 6/29/2018 9:08:40 AM           200 Critical         Windows has shutdown: ...   PS C:\Program Files\PowerShell\6.0.0>    I'm looking for the time I turn on the computer and the time I shut it down each day. I'd like a command line so I can collect the information into a batch file.
How can I know when my computer running Windows 7 was last restarted?   I prefer a solution that doesn't involve searching the event log, but something like wmic or maybe cmd commands.
Ignore python multiple return value Finding value of an expression If $x^2-3x-1=0$ then find the value of $(x^6+1)/x^3$ I tried to solve the quadratic but it became too complicated any way of doing this without a calculator Is it true that $0.999999999\ldots=1$? Limit point of the set $G= \{1/n: n \in \mathbb N\}$? In $\mathbb{R}$ , what is the limit point of the set $G= \{1/n: n \in \mathbb N\}$?  Definition:  A point $p \in X$ is a limit of of E if every neighborhood of $p $ contains a point $q \in E$ $q\neq p$  I do understand $0$ is a limit point but shouldn't it be the case that all the points in [0,1] are limit points by the definition? Java Equivalent to Python Dictionaries What is the design pattern for processing command line arguments Guides on how to install drivers for a Brother all-in-one network printer are either for older devices or are rather complicated as they often involve editing or copying system files in my root directory.  Is there a newer, more convenient way to install the drivers needed? I would like to say something like     The boy, Adam's, favorite toy was a bike.   What is the proper way to say this? Should we sign-then-encrypt, or encrypt-then-sign? How and when is old-releases.ubuntu.com updated? The old-releases.ubuntu.com mirror hosts the repositories for EOL Ubuntu releases. The  currently lists up to 11.10 (or 12.04.3 if you count point upgrades), but the  lists up to 13.04. Why the discrepancy? When will the main page be updated? When will the newest EOL release (13.10) be shifted here? If $a$ and $b$ are relatively prime, prove that $a + 2b$ and $2a+b$ are also relatively prime or have a $\gcd$ of $3$.  I'm very new to number theory so please don't assume I am familiar with some of the terminology. What is the integral of $\int e^x\,\sin x\,\,dx$? I'm trying to solve the integral of $\left(\int e^x\,\sin x\,\,dx\right)$ (My solution):  $\int e^x\sin\left(x\right)\,\,dx=$  $\int \sin\left(x\right) \,e^x\,\,dx=$  $\left(\sin(x)\,\int e^x\right)-\left(\int\sin^{'}(x)\,\left(\int e^x\right)\right)$  $\left(\sin(x)\,e^x\right)-\left(\int\cos(x)\,e^x\right)$  $\left(\sin(x)\,e^x\right)-\left(\cos(x)\,e^x-\left(\int-\sin\left(x\right)\,e^x\right)\right)$  $\left(\sin(x)\,e^x\right)-\left(\cos(x)\,e^x-\left(-\sin\left(x\right)\,e^x-\int-\cos\left(x\right)\,e^x\right)\right)$  I don't know how to complete because the solution gonna be very complicated. When is $\phi(n)$ a prime number? I was thinking about this problem today. If $p$ divides $n$, then $p-1$ must divide $\phi(n)$. But $p-1$ is even for all primes greater than $2$, so must $\phi(n) = 2$ - the only even prime? I feel like this argument is shaky and not very rigorous! Is there a preinstalled or automatic firewall? Does Ubuntu come with a preinstalled or automatic firewall? If not, do I need one?   I've read some articles about the advantages of Linux over other operating systems about security (no need to have antivirus, ...) but would like to be sure. Insert Login IP Ranges using apex in salesforce Is it possible to insert to Login IP ranges via apex? "Lunch" vs. "dinner" vs. "supper" — times and meanings? I've seen cases where a noon-time meal is referred to as dinner, and the evening meal is called supper. There's also lunch around noon followed by dinner in the evening. Is there a particular difference between dinner and supper, or a circumstance where lunch becomes dinner? How to use an ESC I'm new to RC related modules. Today I got my 's Skywalker 20A brushless esc. Manual is .    I also have a brushless outrunner motor (HL3512)    I don't have any device to program the esc's (even the seller hasn't mentioned about such requirement).   The  talks about programming by listening to the beep patterns. But for that it seems that the esc should be connected to a flight controller (it talks about throttle positions etc...). But I don't have any flight controller.  Can some one tell me how to use the esc with what I have? (I have 2200mAh LiPo and  too) Why does a light object appear lighter in your peripheral vision when it's dark? So, I am not sure I can reproduce it via images, but the steps are:  1) At night, open a window and have a look at the surface of the earth  2) Suppose there's an object that reflects a tiny amount of light  3) When you actually try to focus your eyes at this object, you either don't see anything (depends on the amount of light it reflects) or you can hardly see it  4) When you focus your eyes on something that is 3-10 metres away, you can easily see this object with your ambient vision. Not the details, but it seems that it reflects more light.   Why does it happen? Entry to The US before 30-day grace period for student visa The F student visa allows me to enter the US up to 30 days before the program starts. For starting to set up things it is of my interest to arrive sooner than that. How hard is it to travel there beforehand with a tourist visa (waiver) and leave to, say Mexico, to then re enter on a proper date within the 30 days with the student visa? This seems easier than requesting for a status change inside the US from tourist to student.. I got a positive definite matrix $B,$ that is, $V(x) = x^TBx &gt; 0$ for any vector $ x \neq 0.$  I want to show that $ \lambda_\min \|x\|_2^2 \leq V(x) \leq \lambda_\max \|x\|_2^2$ for any $x \neq 0,$ where $\lambda_\min$ and $ \lambda_\max$ are defined by $$ \lambda_\min = \min \lbrace | \lambda|: \lambda \text{ is an eigenvalue of } B \rbrace$$ and  $$ \lambda_\max = \max \lbrace | \lambda|: \lambda \text{ is an eigenvalue of } B  \rbrace$$  Any hint please?
