How can I change user name of taskmanager processes?

Why do this? Just create a new user account called Stan as UsernameIssues said, move you stuff from the User account to the Stan account then test. Once you are sure all is well, delete the User account.

I plan on doing that -- but meanwhile I had examined the long post on changing user names at:
How To Change A Windows Account Name And User Profile Folder Name - gHacks Tech News

In that discussion two people said they ran netplwiz and it worked for them. But none of the other participants in the thread replied to them.

As a test, I used netplwiz to change an unimportant user name that I had partially changed previously using the methods discussed earlier. netplwiz fixed two previously known failures:

1) Task manager now reflects the change.
2) The change took effect here: [start] [control panel] [system and security] [system] [advanced system settings] [system properties] [advanced] [user profiles] [settings].

The user I changed did not have any programs installed, so I don't know what the effect would have been -- such as hangups, user settings, add-ons to Firefox, etc.

I did not try it on my everyday user name.

I backed up my main everyday user profile to a local HDD using Windows Easy Transfer. Then I ran netplwiz [properties] and changed the username from User to stan and saved.

Task Manager now displays user name as stan instead of User. And the profile name in [start][right click computer][properties][advanced system settings][user profiles] has changed from User to stan.

In total, I have made the following six changes to convert the user name User to stan:

1 Created a user, admin, as administrator to work from.

2 In [Control Panel] [user accounts] [ manage another account] [User] [change the account name] Changed User to stan.

3 With File Explorer, in folder \Users\
Changed sub-folder folder name from User to stan

4 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\
Changed ProfileImagePath value from c:\Users\User\ to c:\Users\stan

5 HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\
Changed RegisteredOwner value from User to stan (I don't think this was necessary.)

6 With [Run] [netplwiz] [properties], changed username from User to stan.

I have run various applications and the seem to be working correctly.
