Wrong Program Installation Dates!

I upgraded to Windows 10 a week ago. I noticed in Control Panel / Programs & Features that about 30 programs have an "Installed On" date of yesterday when they were actually installed ages ago and another 20 or so programs have an "Installed On" date of 10 June when I upgraded to Windows 10. The rest on the dates appear to be correct. this also happens on my laptop I did a clean install on a few months ago so it looks like a bug in Windows. It's actually quite irritating since I like to sort my programs by date just to see if anything has been installed recently without my knowledge.

What's going on and why isn't Windows showing the actual installation dates?

You will probably find that yesterday you had a significant W10 update which has reset the dates on a number of your programs.

Look in Reliability History to see what has been going on. (Type reliability in the search box to access this.)

There were no updates yesterday. These installation dates were fixed in Windows 8.1 so why do they keep changing in Windows 10?

I don't know but I've noticed that there is a match between the Installed on date and the date of the program file folder in either the 64bit or 32bit program folders. Could you have something that is changing the date of these folders?

No the owning folder and program .exe file dates are the original installation dates. It's a mystery why they appear as a different date in Programs & Features. Other people are also having problems - see Programs installed on date keep changing

Is there a way of rescanning and resetting the "Installed On" dates to fix this problem?
