If you are using Windows XP and this one will not stop, here are some tips. This is a fairly simple problem to solve. First of all, let me say that I know how annoying this problem can be. I hated sitting still watching the computer while waiting for it to go off.
You can unplug the wall outlet or press the power button for more than four seconds, but this is not the right way to shut down your computer. Every time you make an incorrect shutdown, you further damage your system. There are several reasons why XP will not stop.
First of all, you want to update your virus definitions when performing a full scan. The same with your spyware cleaner. A virus or spyware running in the background can interrupt your system when you close. These stubborn programs do not want to be closed and continue to try to work. In most cases, the main reason why XP will not shut down is due to a corrupt registry.
When Windows tries to shut down. It references the registry to see if any parameters have been changed. If it encounters corrupt entries or registry keys that are trying to reference software that is no longer on your PC, it waits by default for the full 30 seconds per program. So, you have to clean and repair your registry. By installing and installing the software, you create registry keys. Uninstaller programs never do a complete job and leave entries. You must delete them from your system.
Over time, your registry will be swollen and slow. This causes slow starts, slow shutdowns, blue screens, slow program load times, and other annoying problems. The best way to clean and repair your registry is to use a third-party program designed for this purpose. You can do this manually, but it is not recommended. Delete or modify the wrong file and your computer may become unusable or unstable.
It is much easier to use safe and effective software and do not delete any entry needed to run Windows. The whole process can be done in less than a minute. Running a scan on a fairly new computer has generated more than 300 errors. The PC on which we performed the analysis was less than one month old. So you can imagine that an old computer will have a lot more errors and bad entries.
Once you have cleaned and repaired your system, it should work as you did when making the initial purchase. Some systems became so corrupt that the computer would take more than 30 minutes to shut down. Computer technicians love this problem because it is easy to repair. For service calls, they will carry repair software on a CD or USB key, perform a quick scan on the PC and repair it. Now you can buy the same software that they use and save you a service call fee. Or a trip to the store.
