I'm looking at the Uniblue DriverScanner, and see mostly exe files, and 
a few dll files.  They may all relate to the uniblue program itself.  
There's a language folder there, and a x64 folder there. x64 has the 
installer. Otherwise, there is no reference to anything that looks like 
a 26 dll, nor is there a list of drivers the program might want to 
examine for age.  Of course, all of this should have been uninstalled.

Although, the Win7 indexed search is very fast to find something there 
are times when it flubs (possibly since I don't know all the tricks one 
can use in a search). looking for 26.dll has turned up nothing an either 
a folder or inside a file. Supposedly, Uniblue supply an answer in 24 
hours. If not, I'll try Winamp.

I'm looking at System32 entries right now. I see folders such as spool, 
speech, setup,restore, and lots of dll files.  Some of the "p" dll files 
are p2psvc.dll, packager.dll, p2p.dll, and python27.dll. No 
python26.dll, and nothing starting with py other than the 27 file.

Standard. Interesting dependency. I considered Active once, but did not 
install it.

What is the outcome based on what I wrote about not Active?

If so, how I can I tell?

Nothing happens that I can detect. I'm looking at Properties of it. It 
shows
   Start in: c:\Python27.
   Type of File: shortcut (link).
  Location: ...\star menu\programs\python2.7

Interesting under the Security tab it shows Wayne with only special 
permissions. No Read, Write, Read & Execute(!!).  Admin allows all but 
special. Users allows Read&Execute and Read. Same with Everyone

Under Details tab Name is IDLE(Python GUI) link. Folder Path: 
c:\ProgramData\Microsoft\Windows\Start... I can see nothing past "Start..."

Nothing but a momentary circular arrow icon.  Thinking I guess.

A black command window comes up very briefly.  It looks empty, but it's 
really gone quickly.

I'm removing it nevertheless unless your answer to my Active above has 
some relevance to keeping it.

In the last 24 hours I've re-installed 2.7.2 twice. The last time was 
around 7-9 pm last night. I don't see how doing it again is going to 
help.  If there's a registry issue, then I need to figure out how to 
resolve it.

Apparently so.

Who know what the cause is? Maybe Uniblue.  I hope not. :-)
