Since the tenth version of the operating systemWindows today is the most popular, many users want to install it. Unfortunately, there is often a problem with the fact that when you upgrade Windows 10, it hangs at 99 percent of the process. What is the reason and how to deal with this, see below.
In general, the process of updating to "dozens"99 percent is not the only problem. In fact, there are many more situations with similar symptoms, when the process hangs dead.
Among all that is encountered, the following points stand out:
In all cases, when upgrading to Windows 1099% of the time, the LED signaling the access to the hard disk, stops blinking and lights up constantly. You can reset the computer to its initial state by forced reloading by long pressing the power button and then turning it on. But in this case the update will be completely canceled.
Of course, provided that the user hasboard there is a minimal configuration required for the installation of Windows 10, and too slow communication, the above processes only seemingly hovering. In fact, they simply can take too much time (even about 20 hours). Nevertheless, we will dwell on the case when the update of Windows 10 has grown by 99 percent. What can be done in this situation?
The reasons for the occurrence of such failures can be foundlots of. It should be borne in mind that the conflict can occur at the software and hardware level, even if it meets the minimum requirements.
Sometimes the problem may be the presence ofmultiple hard drives. According to the representatives of Microsoft, Windows 10 hangs when a removable SD memory card is inserted into the card reader. The same symptoms are also characteristic for cases when copying files is made to a removable USB-drive. True, the process can be completed with time, but Windows itself will become unlicensed, and it is completely unclear why.
Finally, a crash can also occur in the service itself of the "Update Center", if an upgrade is made using it.
But let's return to the situation when the update of Windows 10 has grown by 99%. In the case of additional hard disks and SD memory cards, the problem can be solved quite simply.
The card should be removed from the card reader, and harddisks, if possible, disconnect by pulling the corresponding SATA cables from the hard drive connectors. In addition, it is desirable to completely disconnect all other peripherals, leaving only the monitor, keyboard and mouse (for laptops - just a mouse). Perhaps, if the Windows 10 update is too much, the problem can be solved in this way.
Another solution to the problem is when Windows 10hangs at any stage of the upgrade, is to deactivate the update service itself, because it provokes this type of failure in the source system.
To do this, it is called "kill"process. The service can not be terminated in the "Task Manager", so you will have to use a special section called from the "Run" menu (Win + R) with the services.msc command.
In the right window of the editor you need to findservice Windows Update, and then right-click to bring up the context menu where the "Stop" line is selected. Do not forget that the antivirus software installed in the old system can also negatively affect the upgrade, so you should deactivate it during the upgrade process by selecting the suspend command in the corresponding menu (either for the maximum possible time or until the next reboot) .
Now look at another commonthe situation. If the Windows 10 update has dropped by 99%, you can try to troubleshoot the problem by using the diagnostic system utility to check the operation of the update center itself.
To do this, first we call the "Run" console, where we write the msdt / id string of WindowsUpdateDiagnostic.
In the appeared window we use the line"Advanced", which is located at the bottom, in a new window, tick the line for the automatic application of the fixes, click on the start link on behalf of the administrator and click the "Next" button. After that, it remains to follow the instructions of the system, and after the diagnostic process it will be possible to start the re-installation of the "dozens".
As you can see, situations when Windows 10 hangs onsome stage of the upgrade, there may be quite a lot, and each of them has its own solution. However, sometimes problems can be observed in an already installed system. For example, very often Windows 10 hangs when searching for updates. It's hard to say what it's connected with. Perhaps, the problem is in a bad connection, perhaps the update is affected by some already installed package. In general, such cases were not deliberately considered, because, the described type of fighting refers specifically to attempts to upgrade the existing OS to the tenth version. But here, too, we first need to find out the cause of the computer's hanging up and only then make a decision on how to fix the problem (although, it is believed, all the above-described tools are good regardless of the root cause). At the worst, if it does not help at all, it's better to download the "clean" installation distro, completely remove the old system and only after that install Windows 10 (and even format all hard disks and logical partitions).
