Step 3 – Clean Out The Registry

Problems in the registry database can often cause msidcrl40.dll errors showing on your computer, along with scores of other system problems. The registry is a vital database which stores all your file and program settings. These settings are constantly accessed by Windows as it needs to read them whenever you ask it to run a program. The errors in the registry are a direct result of entries becoming corrupted or damaged due to the way Windows access hundreds of registry keys at the same time. Because it operates at such high speed, Windows often makes mistakes when saving the registry keys, which ultimately corrupts them. You need to repair the registry by cleaning out errors inside. The easiest and most efficient way of doing this is by using a ‘registry cleaner’ to scan and fix errors for you.
