However, we can take roundabout methods to check the installation date in Windows PC. Let us look at a number of ways you can find out about the accurate date of installation.

Don’t get surprised, if Windows is displaying incorrect time and date because the software utilizes BIOS data to determine the current clock time.

Readers should replace the CMOS battery, and it is available for less than $1 on eBay or Amazon.
