Because several readers reveal their computer responding slowly, I’m submitting a summary listing of general steps you can take to solve the CO_E_FAILEDTOCLOSEHANDLEissue, and briefly discussing the three most common causes : malware, uncontrolled applications, and lack of maintenance.
Possibly the greatest contributor to a poorly performing computer is malware.
Action 1. Update the definitions of your anti-virus and operate a complete scan of your hard drive in Safe Mode. Resolve any unfixable problems. Note that some viruses need additional measures until they could be removed; typically a websearch will locate specific directions or a particular removal tool. If you fail to find a answer, use the BC forums to obtain help.
2. You’ve recently saved an application, and if the slowness is unanticipated, the problem might rest there. Check this by entirely removing it. A user will normally perform a web search about the application before downloading it because in most instances, any possible difficulty with malware or inferior performance will have surfaced.
Action three. Adware and Spyware can drastically effect your personal computer’s functionality, and these are throughout the Internet.
Experienced users will routinely run two or three of these applications, because each company has its own criteria for what constitutes spyware and will simply search against their own set. (A record of very great, free antispyware programs is given by BC). Again, solve any open issues before proceeding to the next step.
For additional reading about Malware and some malware removal applications, use BC’s Tutorial section; most of the programs have quite good Help documents that clarify how they work as well as the special characteristics of each.
Stage 4. Review programs that self-launching on startup. You pc can be a arena for your consideration. Many programs, for instance, install a rapid-start feature which permits them to be opened fast; other programs may contain an automatic update feature that requires them to be working in the background. Your launching Windows are slowed down by each of these and each requires a small bit of sources while your computer is running.
The simplest method to examine and than to handle start-ups will be to utilize one of the numerous small utilities available (see the Bc list of free programs). If, for example, you have Spybot Search and Destroy, you may use its startup tool that lists startups and enables you to show off any you don’t want. If you’re uncertain about what could be safely removed, remember that Bc maintains a quite complete Startup Database that includes information about whether the questioned item is needed, elective, or not needed.
At the same time, remember that all those symbols on your Background also take a small amount of boot time to place themselves.
Absence of Care
Stage 5. Delete unused programs and transfer old files into a CD. Unplayed games, lots of family pictures, zipped files that you have opened, applications you have not found in two years, software for that old printer you put away last year—these are a few types of files you can delete. Then use Window’s Disk Clean-up to remove temporary internet files, temporary PC health files, etc.
(Note for high level users: some professionals would comprise the added care step of cleaning up the Windows registry, and there are plenty of apps to help try this. For the most part, so this step is not included, you can do significant harm by making registry changes, registry care will not make a major difference, and unless you are really comfortable with Windows, and cautiously make copies of the registry
Stage 6. Have it mend CO_E_FAILEDTOCLOSEHANDLE.
Action 7. Defragment your computer.
Hopefully, now that you have have concluded, you’ll find a marked improvement in pc performance.
