DLLs |
Here you can delete unnecessary DLLs which are
no longer in use.
What are DLLs?
DLLs (Dynamic Link Libraries) are programs not executable on their own. They
contain information that can be used by other programs. For instance a DLL can
offer the function to access the internet. This DLL can then be used by a
browser, a mail-client, chat-software and other internet-compatible software
without forcing the programmers to code this function on their own.
Why should I delete DLLs?
If a program needs a DLL it copies it into the Windows directory during
installation. If the program is uninstalled these DLLs remain in the Windows
directory, because the software cannot "know", if there is another program
needing this DLL (if a program does not find a needed DLL it does not run).
Windows has an internal list of all DLLs and saves the information about how
many programs use a specific DLL. WinSpeedUp searches this list for DLLs which,
as Windows "says", are not used by any other program.
Advantages of this function: you get more free disk space and accelerate
Windows, because there are less DLLs to administrate.
How can I delete unnecessary DLLs?
You cannot specify which DLLs can be deleted without a risk. Therefore you
should create a backup first: hit "Manage Backup...". There choose the DLLs you
want to back up from the list on the left side and then click on "Create
Backup ->". The backups are saved in the subdirectory "DLLBackups" in the WinSpeedUp directory.
After creating the backups(s) close the dialog "Manage
Backup", select the DLLs
in the list you wish to delete and click "Delete DLL(s)".
Now go on working with your computer as usual and keep looking for error
messages or non-running programs. The error messages mostly show the DLL which
has not been found. Remember this name and restore the file with WinSpeedUp.
Restore backup
In WinSpeedUp on the tab "DLLs" click on "Manage Backups...".
Select the DLL
on the right side and hit "<- Restore Backup".
Hitting the button "DLL Properties" shows you some short pieces of information
about the selected DLL.
