In my Previous Article, I showed how to Find Your Computer’s Windows Installation Date and Time, and now I am gonna show you How to Change Windows Installation Date and Time Using the Registry Editor.
Change Windows Installation Date using Registry Editor:
Step 1: First of all Open “Run” dialog box. To do so you can either do it by typing “Run” in the Start Menu search or by pressing the “Win+R” key combination.
Step 2: Now type “regedit” in the box that appears and hit enter. You can also type “regedit” in the Start Menu search to open Registry Editor.
Step 3: Navigate to “HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > Windows NT > CurrentVersion > “ in the Registry Editor Windows.
Step 4: You will find a key named “InstallDate” in the Right sidebar as shown in below image.Just Double Click on it.
Step 5: A new popup box will appear showing numerical value. This is the number of seconds between 1/1/1970 and your installation time.
Step 6: To change your Windows installation date just add or subtract the duration by which you want to change your date. For Example – If you wish to add one day to your installation date, then add “60x60x24=86400″ to the value.
If I wanted to add one day to my installation date, I would change the value to “1350224291″. Now Click OK after that.
That’s it, Now go and Check your Installation Date and See the Difference.
