The day before yesterday, a HP ProBook laptop was functioning properly, equipped with an Intel Core i7-6500U 2.5GHz CPU and 8GB of RAM. However, the following morning, the machine running Windows 10 was running exceptionally slow, and the Windows taskbar was unresponsive. Additionally, some operating system functions such as the network manager were not accessible. The decision was made to restart the machine, but upon doing so, Windows became stuck on the loading page.

After attempting to diagnose the issue using various tools, including a hard reset and booting into safe mode, which resulted in automatic repair leading to a black screen, the machine was restarted once again. However, it took an extended period of time for Windows to finish loading, eventually showing the login page.

Although the Windows system is still functional, it is unstable and exhibits significant slowdowns, with applications taking several minutes to open. The author has previously experienced similar slowdowns and is questioning whether this is to be expected and how to prevent it from happening in the future.

Laptop has HDD:

Out of nowhere, I encountered a blue screen error, which remained stuck at 0% complete for an extended period of time. Eventually, I had to restart the system manually, which took approximately 15 to 20 minutes. Upon restarting, I was presented with a login screen that did not have a password field. I restarted again, and this time it was faster. The next login screen had a password field, and I was able to log in. However, opening any application took an unacceptably long time of 2 to 3 minutes.

Based on the accepted answer, it is suggested that I should consider completely replacing the operating system.

It has been more than a month since I reinstalled Windows 10, deleting all the old MBR-based partitions and creating new GPT partitions. During this period, the new Windows 10 installation has been responsive, and I am satisfied with its performance so far.
