To start using any computer, they all have a common process that goes from pressing the power button until the Windows desktop appears. Although the process is the same on all computers, the time it takes to complete differs for each one. If our PC takes forever to start we should not be surprised as it is a fairly common problem.
Some computers boot in 20 seconds and others require minutes to complete the entire boot process. Quite different numbers that can cause the despair of many users, who see how their computer suffers more than they want to start up.

Reasons slowing down the PC startup
That our computer takes a long time to start is not something accidental and can occur for different reasons, some of them related to its hardware. The more powerful the computer, the faster it should boot. This is something that mainly helps the presence of a disk SSD instead of a conventional HDD, since it will allow us to boot in a matter of a few seconds.
Another factor that greatly influences it is the number of files stored . As we fill the hard drive with files and programs, it will cost the system more to log in. In addition, programs load libraries and services at the beginning of the system, which has an effect on a notable slowdown in boot speed.
Other reasons that have to do with the slow start of the system, especially after an update, may be because some important files have been corrupted. The presence of a virus can be another reason why it is difficult for the computer to start up more than desired, as well as problems related to the fragmentation of the hard disk.
All or some of these factors can make a quick boot of our computer turn into endless torture.
Tips to improve starting
If we want to get our PC to start up as quickly as possible, perhaps we should spend some time knowing what happens to try to solve it. If the hard drive is full or quite busy, we should consider cleaning everything that we do not need. We must also review all programs start the same time as Windows and do without it in case we do not need it. In case we have a traditional hard drive, it would not hurt to defragment it, and to the best of our ability, try to change it for an SSD disk , we will notice the difference.
Nor should we ignore the possibility of carrying out a scan with our antivirus , in case some unwanted “bug” has slipped into us or executing the SFC command , so that it is in charge of verifying and repairing those system files that are missing or damaged. and that may be negatively affecting the startup of the system.
Although it may seem that we cannot do anything to avoid the slowdown of Windows when it starts, the truth is that it is in our power to do everything possible to gain a few seconds from the clock and avoid getting frustrated every time we press the power button of the PC.
