This is a simple utility designed to help you find out if your hard drive has reached the end of its life and if it is possible to repair any bad sectors. However, before we continue on the program let's take a brief look back. What is a bad sector? Hard disks are known to write data to block drives (sectors), each time a hard disk updates a sector, it also updates a control sum (stored immediately after the sector data). When a sector is read from your hard drive, it is expected that the cumulative sector check will match the sector data, if this is not the case then bad sectors have probably been created. The appearance of bad sectors can come from either a power outage during recording or some other hard drive malfunction for some other reason such as a fall, mechanical failure and more. The question is: Can the bad sectors be repaired? NOT always, however, if the data stored on the domain is just invalid, but your hard drive is working properly, you can repair the bad sectors that have been created. However, before you start you should first see if your disk has bad sectors. To do this, run the HardDisk Validator application, select Read and press Start to start the diagnosis.

Windows has a boot detection and optimization mechanism that is activated on each boot, analyzes the operating system boot performance and takes the necessary steps to make it as fast as possible, thus providing a better user experience. Optimization includes transferring bootloaded files to the fastest areas of the hard disk and optimizing services and drivers for the current hardware and many more steps. The whole idea is to give the user access to the operating system as soon as possible.
Have you ever noticed that over time, Windows 8 / 8.1 and 10 startup times start to get worse instead of better, as in Windows 7? This is because, in later versions of the operating system, hybrid shutdown is enabled by default and the computer never shuts down completely, which means that boot detection and optimization are rarely or never performed.
The solution; You can restart your computer several times, leaving a few minutes between each reboot. This will cause the boot to be detected and optimized and after a few reboots, things should be much faster. MultipleRebootScheduler is a tool that optimizes Windows boot time by performing several reboots in succession with a few minutes between each reboot, which in turn enables the built-in system boot optimization.

If you do not enable this option, you may need to enter the user login password each time the computer is restarted. The program is completely portable and does not require installation.
