Because several readers reveal their computer responding slowly, I am submitting a summary record of general steps you can take to resolve the 6721 (0x1a41)issue, and briefly discussing the three most common causes : malware, uncontrolled applications, and insufficient maintenance.
Maybe the most important contributor to a badly performing computer is malware.
Step 1. Update the definitions of your anti virus and operate a full scan of your hard drive in Safe Mode. Solve any unfixable issues. Notice that some infections require extra steps until they could be removed; generally a web search will locate specific instructions or a special removal tool. If you fail to find a answer, use the BC forums to request support.
Step Two. You have recently downloaded an application, and if the slowness is surprising, the issue may rest there. Test this by completely removing it. A smart user will usually perform a websearch about the application before installing because in most cases, any possible difficulty with malware or poor performance will have appeared.
Stage three. Adware and Spyware can radically impact your computer’s operation, and these are all over the Web.
Revise the explanations of your antispyware applications and scan your hard drives in Safe Mode. Experienced customers will regularly run two or three of these programs, because each business has its own standards for what constitutes spyware and will simply search against their own set. (A list of really good, free anti spyware applications is supplied by BC). Again, solve any open issues before proceeding 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 good Help documents that explain how they function as well as the distinctive characteristics of each.
Step 4. Review programs that self-launch on startup. You pc may be a battleground for your attention. Many programs, for instance, install a rapid-launch feature that enables them to be exposed swiftly; other programs may comprise an automatic update feature that demands them to be operating in the background. Each of these slows down your debut Windows and each requires a small bit of sources while your personal computer is running.
If, like, you have Spybot Search and Destroy, you can use its startup tool that lists startups and lets you to turn off any you don’t need. Remember that BC maintains a really complete Startup Database that includes information about whether the inquired item is required, elective, or not needed, if you’re unsure about what could be safely removed.
At the same time, remember that all those symbols in your Desktop also take a small number of trunk time to place themselves.
Lack of Upkeep
Stage 5. Clean-up your hard drive (preparation for Stage 7). Delete unused applications and exchange old files to your CD. Unplayed games, lots of family pictures, zipped files that you have opened, applications you haven’t found in two years, software for that old printer you threw away last year—these are a few types of files you can delete. Then use Window’s Disk Clean-up to delete temporary internet files, temporary PC health files, etc.
(Note for high level users: some experts would include the additional upkeep step of cleaning the Windows registry, and you’ll find plenty of applications to assist do this. For the most part, registry maintenance will not make a critical difference, and unless you’re really comfortable with Windows, and carefully make copies of the registry, you may do severe damage by creating registry modifications, so this measure is not included
Action 6. Run scandisk / checkdisk in Safe Mode. Have it fix 6721 (0x1a41).
Stage 7. Defragment your pc.
Hopefully, since you have have ended, you will find a marked improvement in computer performance.
