Because several readers come up with their computer responding slowly, I am submitting a summary listing of general steps you can take to solve the Security Descriptor Structure Is Invalidproblem, and briefly discussing the three most frequent causes : malware, uncontrolled applications, and lack of care.
Maybe the greatest factor to a badly performing computer is malware.
Stage 1. Revise the explanations of your anti-virus and operate a complete scan of your hard disk in Safe Mode. Resolve any unfixable problems. Notice that some viruses require additional steps until they could be removed; normally a web search will locate specific directions or a special removal tool. If you fail to find a answer, use the BC forums to obtain support.
Step Two. You have recently saved an application, and if the slowness is unexpected, the problem may dwell there. Check this by completely removing it. A sensible user will typically perform a internet search about the program before installing because in most instances, any possible trouble with malware or inferior performance will have surfaced.
Action three. Adware and Spyware can dramatically effect your computer’s functionality, and these are throughout the Web. A very recent research showed that one out of every 20 executable files on Web sites is spyware, and 1 in 25 domains include at least one piece of spyware waiting for sufferers.

Experienced customers will often operate two or three of these programs, because each company has its own criteria for what constitutes spyware and will only search against their own established.

For additional reading about Malware and some malware removal applications, use BC’s Tutorial section; most of the programs have quite great Help files that clarify how they operate too as the unique characteristics of each.
Step 4. Evaluation applications that self-start on startup. You computer may become a arena for your interest. Many programs, for example, install a fast-launch feature that enables them to be opened promptly; other programs may comprise an automated update feature that demands them to be working in the background. Each of these slows down your launch Windows and each requires a little bit of sources while your personal computer is running.
The easiest approach to review and than to manage start ups would be to utilize one of many little utilities available (see the Bc list of free apps). Remember that BC maintains a really comprehensive Startup Database that contains info about whether the item is required, optional, or unnecessary, if you are uncertain about what may be safely removed.
At the same time, remember that those symbols on your Desktop also take a modest number of trunk time to put themselves.
Absence of Maintenance
Stage 5. Delete unused programs and transfer old files to your CD. Unplayed games, lots of family pictures, zipped files which you have opened, applications you have not found in two years, software for that old printer you put away last year—these are some examples 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 upkeep step of cleaning up the Windows registry, and you’ll find several applications to assist try this. For the most part, so this step is not contained, you may do serious harm by making registry modifications, registry care won’t make a major difference, and unless you’re quite comfortable with Windows, and cautiously make backups of-the registry
Action 6. Run scandisk / checkdisk in Safe Mode. Have it mend Security Descriptor Structure Is Invalid.
Action 7. Defragment your personal computer. Windows tends to put new documents in any available open space; defragging will place associated segments of files closer together therefore your read arm has less going around the hard drive to do, saving wear and tear while speeding up programs.
Hopefully, now that you have have ended, you will see a noticeable enhancement in pc operation.
