I'm positive I wrote a similar message this morning and intended to edit the message. However, I've searched the likely sub-forums and can't find the message. Since the two are similar, an answer to this one will answer the second since the initial post is subsumed within this text.
I'm uninstalling applications that I no longer use. Here's a rough list:
Application # installs with different ver #'s
WindowsMobileDevice 1 icon for the original + 1 icon for the
Intel network and Intel Pro 1 of each
Microsoft Visual C++ 9
Windows Driver Package 13
I think the Drive pacages should be left as is since they could easily refer to different drivers
within the same package. However, I suspect regarding the balance of the above, if the latest date of the duplicated listings is kept and earlier versions removed I should be okay.
The second part of this question relates to files left over after an application installs and files the application backup up prior to install in the event the user needed to revert to the earlier version (I'm assuming that many applications, particularly MS, do not delete the prior or even their install files after installing?). Are these files keep in a certain location and do they have similar filename nomenclature so that I could go about safely deleting them all for more room?
