Sometimes you want to see how long the computer/server has been running since it was powered on.
So is there a way out? How do I see how long the system is running?
This site to organize the following several solutions:
1, inWindows XP: Click "Start → run", enter "CMD" and return to open a command prompt window. Type "SystemInfo" and enter, wait a moment you will see a summary of your own operating system, which has a behavior "system startup Time", the subsequent time units are also accurate to the second. How's that, it's amazing? It is important to note that the "System startup Time", which is the "system uptime", means that the system starts from the start to the current elapsed time, and when the machine restarts, it starts again from zero.
2. Click "Start → run", enter "CMD" and return to open the Command Prompt window. Enter "NET statistics WORKSTATION", in the first line of the command, you can clearly see the boot time
3. UseMicrosoft's Uptime.exe tool. The relevant and use introduction page is: http://support.microsoft.com/kb/q232243/
If you are too bothered to go to Microsoft site, here is the direct: http://download.microsoft.com/do ... t4/en-us/uptime.exe
Executing uptime/s at the command line will display the log of the system switch machine.
Note: There are several restrictions on this uptime.
1. Dependent on the event Log Service. If this service is re-established, it will affect the accuracy of the uptime.
2. There are records in the event, and if not, no. If Dr.waston for error message is not allowed.
3. Uptime and other methods actually calculate time by invoking the PDH.dll of the system. PDH = Performance Data Helper is an API call to query system performance under NT/2000/XP. PDH does not support XP Home Edition, and the support for XP Pro also requires that XP's simple file sharing be turned off. 2000/xp comes with Pdh.dll, while NT can be downloaded for free.
4. PDH or uptime-the win9x/me machine has a 49.7-day limit, that is, every 49.7 days (continuous boot), it should be zeroed, re-count. This is because 49.7 days = 4,294,967,295 (ms)/1000/3600/24. This is the limit of 32 bits. However, for NT/2000/XP, you can store up to 500 million years of time.
5. PDH provides the function can remotely detect the machine's uptime, but need to open the Remote Registry service, if there is firewall, to ensure that port 445 (microsoft-ds) open.
6. Under administrative authority, uptime run more accurately than non-admin. 3. With a small command you can see the initial installation time of the system, but also to see the system startup time, operating system version, installed patches and many other information. This command is Systeminfo. Press "win+r" shortcut key, enter "CMD" carriage return, then enter "systeminfo" command in the command Prompt window and return. The following is the full cmd command:
