Scan your Pc for Free to Check for Windows Registry Errors
 

If you are experiencing problems with your PC, or it's no longer
performing as it used to, the likelihood is your Windows registry is
overloaded with redundant entries created by the Windows operating
system or other software.
Windows communicates with its registry dozens of times every second and
broken registry keys can make that communication difficult and slow.
Even moderate use of a PC running Windows could result in numerous
registry keys and files spread across the Windows registry. Many of
these entries are no longer needed or used by Windows and may well
disrupt the smooth running of your system.
After just a few days these Windows registry keys and files can begin
to accumulate and, over time, will cause your PC to slow down, trigger
'missing' .exe or .dll files messages and finally stop running
altogether. If you've had your system for some time then you'll be
astonished at the number of unnecessary Windows registry keys and files
hanging around, just waiting to strike. Deleted programs often leave a
few Windows registry keys and files littered around and these are
potential problems in the making.
If you'd like to know just how many redundant Windows registry keys and
files are lurking in your PC just download and run Error Nuker - it
will scan your Windows registry and give you the report for FREE.
