Hi. My question. I have Windows 10 up to date. Today is 8.11.2021.
Where i can find which version of Windows 10 i had 23.03.2021? What version i had 23 march 2021. Thx. Is this possible? I dont format disk also.

Hi, the oldest record of that would be derived from here:


The oldest available will depend on when you last received a feature update which clears the record of your Update History.

This also occurs if you perform an in-place upgrade repair.

Threfore there my be no record for a date that far back.

Another option would be if you use disk imaging regularly and routinely as is so very often recommended here, and you still had a disk image from that time.

If you have upgraded your PC each time there was a new version, then each previous version, its installed key, and the date you upgraded it to the next version are stored in the Registry. You can read this information with ShowKeyPlus

Here is one on my Windows installs that was originally supplied by the OEM with Windows 7 Home Premium and took the free upgrade to Windows 10 on 29th July 2015. Including that upgrade it has been upgraded 15 times all together.



You can also read that information directly from the registry in Regedit, look at HKEY_LOCAL_MACHINE\SYSTEM\Setup
