Andy Kurth updated VCL-1013:
----------------------------
    Description: 
The Windows code does several cleanup actions during pre_capture.  Some of them 
are a bit crude and could cause problems with things such as Windows Update.  
For example, the following are being deleted:
* C:\Windows\ServicePackFiles\*
* C:\SoftwareDistribution\Download\*

It would be better to let dism.exe and cleanmgr.exe handle all of the cleanup 
unless there are files known to be 100% safe to delete.

The cleanmgr.exe code has hard-coded registry entries for items to clean up.  
These represent the checkboxes you see when you run _Disk Cleanup_.  The 
options vary based on version and which features are installed.  There are 
options for Windows 8 and later not being used.  This should be updated.

There are other details which should be removed:

* Defragment hard drive - I see no real advantage for this anymore.  It's 
detrimental for some VM images if the image is stored thin.  Under VMware/thin, 
if a file is created and deleted or moved to an empty location, the original 
space isn't reclaimed without special operations (sdelete/punchzero).  Bare 
metal use of VCL is rare these days and I don't see much of a benefit 
regardless.
