Because many readers write about their computer reacting slowly, I am posting a summary record of general things you can do to resolve the Error 1402 Setup Cannot Open Registryproblem, and briefly discussing the three most frequent causes : malware, uncontrolled applications, and lack of care.
Perhaps the greatest contributor to a badly performing computer is malware. Generally this is associated with downloading an application that includes spyware, by not having browser security settings high enough, by carelessly downloading P2P files, or by declining to install security patches regularly.
Step 1. Revise the explanations of your anti virus and run a full scan of your hard disk drive in Safe Mode. Resolve any unfixable issues. Note that some infections need additional steps before they can be removed; ordinarily a websearch will find specific directions or a special removal tool. If you fail to find a answer, use the BC forums to obtain help.
Step Two. If the slowness is sudden, and you’ve recently downloaded an application, the problem may live there. Check this by fully eliminating it. A user will usually perform a web search about the program before installing because in most instances, any possible difficulty with malware or poor performance will have surfaced.
Stage 3. Adware and Spyware can radically impact your computer’s performance, and these are throughout the Net.
Update the definitions of your anti-spyware applications and check your hard drives in Safe Mode. Experienced customers will consistently run 2 or 3 of these applications, because each company has its own criteria for what constitutes spyware and will only search against their own established. (A listing of quite good, free antispyware programs is given by BC). Again, resolve any open issues before continuing to the next step.
For further reading about Malware and some malware removal applications, use BC’s Tutorial section; most of the programs have very great Help files that explain how they operate as well as the special characteristics of each.
Stage 4. Evaluation programs that self-launch on startup. You pc can be a arena for your attention. Many programs, for example, install a fast-start feature that permits them to be exposed instantly; other programs will contain an automated update feature that requires them to be running in the background. Each of these slows down your debut Windows and each needs a small bit of sources while your computer is running.
If, like, you have Spybot Search and Destroy, you may use its startup tool that lists startups and enables you to turn off any you usually do not need. If you’re unsure about what may be safely removed, remember that BC maintains a very complete Startup Database that contains information about whether the item is required, optional, or not needed.
At the same time, remember that those symbols on your own Desktop also take a small number of trunk time to place themselves.
Lack of Care
Step 5. Delete unused programs and transfer old files to a CD. Unplayed games, lots of family images, zipped files which you have already opened, applications you haven’t found in two years, software for that old printer you put away last year—these are a few examples of files you can delete.
(Note for higher level users: some professionals would include the added maintenance stage of cleaning the Windows registry, and you will find several apps to help try this. For the most part, so this measure is not contained, you may do significant damage by making registry modifications, registry maintenance will not make a significant difference, and unless you’re really comfortable with Windows, and cautiously make copies of-the registry
Stage 6. Have it fix Error 1402 Setup Cannot Open Registry.
Step 7. Defragment your pc.
Hopefully, now that you have have ended, you’ll find a marked improvement in computer operation.
