Registry za Windows je jedno mjesto koje treba ostaviti dovoljno dobro, ali samo radi argumenata, što bi se dogodilo ako ste izbrisali cijelu stvar? Današnji SuperUser Q & A post raspravlja o mogućnostima kako bi zadovoljio čitateljsku znatiželju.

Pitanje

SuperUser čitač SkYWAGz želi znati što će se dogoditi ako je cijeli registar sustava Windows izbrisan:

I have been wondering what would happen if I deleted the entire Windows registry (using the following code for instance). Would my PC stop working?

  • cd %TMP%
  • reg query HKCR> RegTest.txt
  • reg query HKCU>> RegTest.txt
  • reg query HKLM>> RegTest.txt
  • reg query HKU>> RegTest.txt
  • reg query HKCC>> RegTest.txt
  • @pause && cls
  • for /f “delims=” %%I in (RegTest.txt) do reg delete “%%I” /va /f

Što se događa ako je cijeli registar sustava Windows izbrisan?

Odgovor

Davatelji SuperUser-a Daniel B i StW imaju odgovor za nas. Prvo, Daniel B:

You cannot delete the root nodes since they do not physically exist. You can, however, delete their contents via Regedit (as opposed to reg).

Regedit hangs as soon as I try to delete HKLMSYSTEM. After resetting the VM (because I am lazy), I get the following screen (the operating system is Windows XP):

(Translation: “Windows could not start because the following file is missing or corrupt: WINXPsystem32configSYSTEM”)
(Translation: “Windows could not start because the following file is missing or corrupt: WINXPsystem32configSYSTEM”)

So yes, deleting stuff from the registry will absolutely positively kill Windows. And unless you have a backup, restoring it is impossible.

Slijedi odgovor StW-a:

Windows stores a lot of critical information in the registry, which is loaded (at least a part of it) during an early stage while booting. If you remove this information, Windows will be unable to find and load critical system files and thus be unable to boot.

Such critical information is the list of device drivers needed for booting the system. This may include:

  • Disk drivers (Floppies, Hard-Disks, CDs, USB Devices, …)
  • Bus drivers (IDE, SATA AHCI, …)
  • File system drivers (FAT, NTFS, …)

However, by default Windows stores a backup copy of the registry. If you have enabled System Restore, you can find such copies in the (hidden) System Volume Information Folder inside the root folder of the system partition. Additionally, even if you do not have System Restore enabled, Windows saves a backup copy of the registry in %WINDIR%System32configRegBack.

You can manually copy the backup files into %WINDIR%System32config to restore the registry data.
