Probably, it is not necessary to say that very many users of computers and laptops running Windows operating systems sometimes (and quite often) after critical failures have to roll back (restore from a control point to a previous state). But the trouble is, many people are shocked by the appearance of the message "an unexpected error occurred while restoring the system 0xc0000022". What to do, because it turns out that it is impossible to roll back the system? It is not surprising that some users who do not know the methods for correcting such a situation immediately try to reinstall Windows. This is just not worth doing. You can do with less cardinal methods. To do this, you just need a “native” system boot disk or something like a Live CD.
Unexpected system restore error 0xc0000022: what is it?
To start, let's dwell on the failure itself. Many people wonder why, when setting a rollback at the boot stage, an unexpected error appears during system recovery 0xc0000022. Windows 7, such a favorite, is not the only system in which such a failure can occur. In the G8 and G8, such a phenomenon is also not uncommon.
In general, if we consider the root causes when the system displays a message that an unexpected error occurred while restoring the 0xc0000022 system, there are basically two main points here: the effects of viruses and the absence or damage of some system components responsible for the rollback of the system. We will analyze both situations.
Virus scan
As follows from the above, recovery does not work, and, as a result, system boot is impossible even in safe mode. To begin with, it is recommended to conduct a comprehensive scan of the computer system for viruses that could lead to such a situation.
It goes without saying that a full-time scanner is not available. In this case, you should use special utilities with the general name Rescue Disk, recorded on an optical disk or USB-drive, which load their own interface and the most necessary software components before starting Windows. If viruses are not detected during the scanning process, and the system with obvious persistence again displays a message that an unexpected error occurred while restoring the 0xc0000022 system, proceed to the next steps. For download, we now use the aforementioned disks (either installation with "Windows" or Live CD).
Unexpected error during system recovery 0xc0000022: how to fix it with the simplest method?
So, we start from a disk or a flash drive, after which, for example, in the case of a “native” Windows disk, we do not install the system, but proceed to the recovery console. In principle, you can try to roll back the system from the corresponding section, but, as practice shows, this will not lead to anything, and the message "Unexpected error during system recovery 0xc0000022" will appear again. It is not surprising, because all the data about the rollback point and the saved parameters are not on optical or USB media, but on the hard drive of a computer or laptop.
Here the command line comes to the rescue. You can call it from the console menu or use the Shift + F10 keys. Now in the window that appears, you need to register the sfc / scannow command and press the enter key. Next, the verification process is activated, during which critical system components, including those responsible for the rollback, will be restored.
Specific methods for corrupt boot record
If the previous method did not give a result, most likely, the user was faced with the fact that the main boot record was damaged in the system. It will have to be restored.
Repeat all the download steps and again get to the command line. Here we write the following commands: first Bootrec.exe / FixMbr, and then Bootrec.exe / FixBoot. In most cases, no further action is required. After their successful execution, as the message on the screen indicates, you can try to restart the system again. In this case, if the recovery is not automatically activated, you need to reboot with the call to the safe mode menu, which uses the boot line of the last successful configuration.
If this does not work, repeat all the steps described above, and add one more to the two previous commands: Bootrec.exe / RebuildBcd (it overwrites the boot sector). After completing this operation, everything should certainly start without problems.
Conclusion
It remains to be added that only the most effective methods that require the use of the command line and boot disk were considered here. Of course, you can try to correct the situation with the help of special utilities designed to ensure that the rollback was launched directly by means of a working Windows, when for some reason it was impossible to restore, but the system is still at least somehow loading. In our case, the technique is designed exclusively for situations where the system does not work at all. By the way, the above methods allow you to restore the system’s performance not only when such a failure occurs, but also in many other cases - a truly universal solution, and this does not depend on the presence of stored control points. They can be used only when Windows starts working again.
