What is the registry?
- The Registry is the central hierarchical database used in
Microsoft Windows operating systems to store information
necessary to configure the system for one or more users,
applications and hardware devices.
Why do I need to clean the registry?
-
When you install an application, new registry entries will be
created. These entries should automatically be deleted when you
uninstall the application. Unfortunately, it does not always work
that way. Sometimes, you will find that some applications fail to
remove their own registry entries. These entries then become
obsolete. Over time, the Windows Registry begins to hold data that
are invalid and obsolete. This invalid data eventually accumulates
in the Registry, slowing Windows down, compromising PC performance
and causing other problems. So, to keep your computer in top
performance, it is recommended that you periodically clean your
Windows registry.

Will Wise Registry Cleaner backup my registry before I click the Fix
button?
- When you click the "fix" button, a backup file will be
created automatically and fast. Then when you click the "Undo
Fix" button, a restore point will show. (This process is fast
because it only backs up those registry entries that will be
changed.)
When I click the Backup button, why does it take so long to
backup the registry?
- When you click the "backup" button, a full backup file
of registry will be created. Because this is a backup your
entire registry, it will be slow.
When I click the "Backup" button, the top bar shows three
registry keys being backed up. The lower bar reads
'Compressing...' What does 'Compressing...' mean?
- Because the backup file is so large, when the backup
is completed, it needs to be compressed to reduce it's
size and therefore use less disk space.

version?
- A minor upgrade can directly install the new version (for
example: 2.0-2.x). A major upgrade needs to uninstall the old
version first, then install the new version (for example:

Why doesn't Wise Registry cleaner check all empty registry keys?
- Because some empty keys are useful and necessary. Windows or
other application need these keys. For example, under the

Wise Registry Cleaner just checks part of registry for empty
keys.

Parameters...?
