There are times when you may need to determine when exactly Windows 10 was installed on your PC. To get this information, you don't need any third party tools. It is possible to get this using only the built-in Windows tools. Let's see how.

While Windows is designed to be operated with a graphical user interface, under the hood of the operating system is a suite of handy command line tools. One of them, called systeminfo.exe, can provide detailed information about your OS and its configuration. The installation date is also included in the output of that little tool.
To find your Windows installation date, do the following:
- Open an elevated command prompt instance.
- Type the following command:
In the output, you can find the line 'Original Install Date':
You can extract the installation date directly using a combination of the systeminfo app and the findstr tool
Enter the following at the command prompt:

Update: Our reader Hossein reports that after a number of upgrades, Windows 10 can forget the original installation date. If you are affected by this issue, it is still possible to find the correct date.
Every time you perform a build upgrade in Windows 10, the operating system stores some bits of information related to previously installed operating system versions in the Registry. By fetching this info, you can see a list of builds that you installed to come to the currently installed version of the OS. This can be really interesting, especially if you have upgraded your Windows 7 or 8.1 OS to Windows 10 and then joined the Windows Insider Preview program.
See the following article:
That's it.

Is it possible to find the date when windows updates were installed on windows server 2003?
If I go to the controlpanel->install/uninstall programs and check the 'Show Updates' checkbox it will show the windows updates that have been installed, but I don't see the installation date anywhere.

I think Get-Hotfix has been available via PowerShell since version 3.
You can run it locally or against remote systems.
Locally:
To get hotfixes for remote system(s), provide it -Computername with your list of systems. (Note: This requires RPC open on the firewall between systems you're querying and wherever you're running Get-Hotfix from)

Psinfo -h will show you the dates of install as well. Psinfo is part of the Pstools goodies.

.Best mods for grand admiral thrawn. These smaller scenarios provide more accessible starting points instead of the standard Galatic Campaign which features over one hundred planets.Now if I am allowed to go on a bit of a tangent, I want to talk about Admiral Thrawn, the namesake of this mod, and why he's one of the best characters in Star Wars canon. It was a massive breath of fresh air to see a Star Wars villain outsmart the protagonists without the use of a super weapon. While all you motherfuckers have been debating if The Last Jedi is 'good,' I am over here reminding everyone that Star Wars Rebels is the best thing to bear the franchise's name in ten years! A significant reason for this was the show's inclusion of Grand Admiral Thrawn as its antagonist from seasons three to five. For once, the Imperials felt like a threat not guided by plot convenience.

How can I check WHEN last check for windows updates was performed - in code (c#/.Net)?
Not WHICH updates are or are not installed, but WHEN last check was performed?
Best of all would be a complete history of when checks for windows updates had been performed, but I can certainly live with only knowing the last check.
