Because several readers reveal their computer reacting slowly, I’m publishing a summary record of basic steps you can take to resolve the Cocreateinstanceex  ]problem, and briefly discussing the three most common causes : malware, uncontrolled applications, and lack of care.
Maybe the most important factor to a poorly performing computer is malware. Usually this is associated with downloading an application that contains spyware, by not having browser security options large enough, by carelessly downloading P2P files, or by failing to install security areas regularly.
Stage 1. Update the explanations of your anti virus and run a full scan of your hard drive in Safe Mode. Resolve any unfixable issues. Note that some viruses require additional measures before they could be removed; generally a websearch will locate specific directions or a particular removal tool. If you cannot find a solution, use the BC forums to obtain help.
2. If the slowness is sudden, and you have recently downloaded an application, the issue may live there. Test this by fully eliminating it. A user will typically perform a web search about the program before getting because in most instances, any possible problem with malware or inferior performance will have surfaced.
Step three. Adware and Spyware can drastically impact your personal computer’s performance, and these are around the Internet.
Experienced users will frequently run 2 or 3 of these applications, because each business has its own standards for what constitutes spyware and will only search against their own set. (A record of very good, free antispyware programs is provided by BC). Again, resolve any open issues before continuing to the next step.
Stage 4. Evaluation apps that self-start on startup. You pc may be a arena for your consideration. Many programs, for instance, install a quick-start feature which allows them to be opened quickly; other programs may comprise an automatic update feature that requires them to be running in the background. Your launching Windows are slowed down by each of these and each needs a small bit of assets while your personal computer is running.
The simplest way to examine and than to handle start-ups will be to utilize one of the many little resources available (see the BC list of free programs). Remember that Bc maintains a very complete Startup Database that includes information about whether the item is required, elective, or unnecessary, in case you are uncertain about what may be safely removed.
At the same time, remember that all those icons on your own Desktop also take a small number of boot time to place themselves.
Absence of Maintenance
Stage 5. Delete unused programs and exchange old files to a CD. Unplayed games, lots of family pictures, zipped files which you have already opened, applications you have not used in two years, software for that old printer you put away last year—these are a few types of files you can delete.
(Note for sophisticated users: some professionals would comprise the additional care stage of cleaning the Windows registry, and there are plenty of apps to assist do this. For the most part, so this measure is not contained, you can do significant harm by creating registry changes, registry maintenance won’t make a significant difference, and unless you’re quite comfy with Windows, and carefully make backups of the registry
Stage 6. Run scandisk / checkdisk in Safe Mode. Have it fix Cocreateinstanceex  ].
Step 7. Defragment your personal computer. Windows will put new files in any available open space; defragging will place associated sections of files closer together so your read arm has less travelling around the hdd to do, saving wear and tear while speeding up applications.
Hopefully, since you have have concluded, you will see a noticeable enhancement in computer functionality.
