Because several readers come up with their computer responding slowly, I am submitting a summary listing of basic steps you can take to solve the The Specified Protocol Driver Is Invalid.issue, and briefly discussing the three most common causes : malware, uncontrolled applications, and lack of maintenance.
Maybe the greatest contributor to a badly performing computer is malware.
Action 1. Update the definitions of your antivirus and run a full scan of your hard drive in Safe Mode. Solve any unfixable issues. Note that some infections require extra measures before they can be removed; generally a internet search will find specific instructions or a particular removal tool. Use the BC forums to request support, if you can’t find a answer.
Step Two. You’ve recently downloaded an application, and if the sluggishness is unexpected, the issue may rest there. Test this by fully removing it. A smart user will generally perform a web search about the program before downloading it because in most instances, any possible trouble with malware or poor performance will have appeared.
Action 3. Adware and Spyware can dramatically effect your personal computer’s performance, and these are around the Web. A very recent study showed that one out of every 20 executable files on Web sites is spyware, and 1 in 25 domains feature at least one piece of spyware waiting for victims.
Revise the definitions of your antispyware applications and scan your hard drives in Safe Mode. Experienced users will frequently run two or three of these applications, because each business has its own criteria for what constitutes spyware and will simply search against their own set. (A record of really good, free antispyware programs is given by BC). Again, solve any open issues before continuing to the next step.
Step 4. Evaluation applications that self-launch on startup. You computer may be a battleground for your attention. Many programs, for example, install a quick-start feature which enables them to be exposed quickly; other programs may comprise an automated update feature that demands them to be working in the background. Each of these slows down your debut Windows and each needs a small bit of resources while your computer is running.
The easiest method to examine and than to manage start ups will be to-use one of the many little resources available (see the BC list of free apps). If you are unsure about what may be safely removed, remember that BC maintains a really comprehensive Startup Database that contains info about whether the item is required, discretionary, or unnecessary.
At the same time, remember that all those icons in your Desktop also take a small number of trunk time to place themselves.
Lack of Upkeep
Stage 5. Cleanup your hard drive (preparation for Action 7). Delete unused programs and exchange old files to a CD. Unplayed games, tons of family images, zipped files which you have already opened, applications you haven’t used in two years, software for the old printer you put away last year—these are a few types of files you can delete. Then use Window’s Disk Cleanup to delete temporary internet files, temporary PC health files, etc.
(Note for sophisticated users: some experts would include the added upkeep stage of cleaning the Windows registry, and you’ll find plenty of programs to assist do that. For the most part, so this measure isn’t included, you may do severe damage by making registry modifications, registry maintenance will not make a major difference, and unless you are very comfortable with Windows, and carefully make backups of-the registry
Stage 6. Run scandisk / checkdisk in Safe Mode. Have it repair The Specified Protocol Driver Is Invalid..
Action 7. Defragment your personal computer.
Hopefully, now that you have have concluded, you’ll see a noticeable improvement in pc functionality.
