方法1：

I don't know if there is some more easy method but you can check the boot time with the help of systeminfo command , after running systeminfo command in command prompt look for “System Boot Time” (for vista)
and look for “System Up Time” for xp. To shorter the systeminfo command output for this subject, use the find command.

For Windows Vista SP1:

Code:

systeminfo| find "System Boot Time"

For Windows XP:

Code:

systeminfo| find "System Up Time"

方法2：

To know the date and time of last boot in XP:

1. Click Start / Run (or Windows key + R)
2. Type cmd to open a command window,
3. At the command prompt type: net statistics workstation

Here you'll find the line like : Statistics since 11/5/2009 4:03 PM , means the line Statistics, shows that the system was started at 4:03 PM .

Look in Event Viewer. You'll find the even details right from the time when the pc was booted. To access Event Viewer select Start -> Control Panel ->
Administrative Tools -> Event Viewer. When researching the meaning of the error, information regarding Event ID, Source and Description are important.
