Hello Ravi, nice to hear from you in another thread. I had this issue a few months ago. I cannot recall exactly what I did to restore everything, but between utilizing the URL you provided, as well as the one listed below, I was able to restore everything except the "Thinkpad Default". Recently, with the "freeze" issue that you are most familiar with, as I explained in that thread, with the power management software uninstalled, I deleted the portion of the registry related to the power config schemes and copied those that were available in my Guest account that I have setup for other family members. This restored all schemes (Windows and ThinkVantage) and brought back the "Thinkpad Default". Recommend backing up your registry before attempting any changes. See if the below URL provides any additional guidance:

Alternatively, you might also try activating the Guest account. Log into that account and review the power schemes setup in that account's registry. Hopefully, you will find the same entries that I did and you can then export that section of the registry forming a ".reg" file". You can save it to your "Shared Documents" folder so you can access it in your regular user account as well. Here's what I did:
1. Save a copy of your registry by exporting it
2. Logged into Guest account
Export this portion from Guest account to my Shared Documents folder: My Computer\HKEY_CURRENT_USER\Control Panel\PowerCfg - I called it powercfg.reg
3. Logged into normal account
4. In registry, deleted My Computer\HKEY_CURRENT_USER\Control Panel\PowerCfg
5. Closed registry
6. Double clicked on registry file created in step 2
7. Opened registry to check that new entries were indeed there
8. Rebooted
9. Set desired power scheme. In my case - Window's Home/Office
If this does not work, then you can always import your saved reg file created in step 1 and get back to your starting point.
Good luck.
