Disability is not beautiful: repair system files Recovery configuration can only repair the data in the registry, if the system file itself is damaged, then you need to use other methods. System file corruption can cause system instability, and even serious problems can not be started properly.

Re-registration & rdquo; DLL file: restore DLL registration status system has a lot of DLL files, they are actually divided into two categories, no need to register the standard DLL files and ActiveX DLL files need to be registered, the latter in the registry The next relevant data, once the data is destroyed or does not exist at all, then an error occurs when calling these DLLs. There are many such DLL files that need to be registered and are related to system functions. When a system function fails, how can you find out the troublesome DLL and re-register it? A better way is to re-register all …&hellip ; Open “Notepad” Enter the following code and save it as regdll.bat, execute it and restart after completion. @echo off for %1 in (%systemroot%system32*.dll) do regsvr32.exe /s %1 System Alternative Initialization: Full recovery of the initial registry System initialization, not just the way to reinstall the system. In the system directory, there is a subdirectory dedicated to the registry database file, and the good news is that there is a subdirectory dedicated to the backup of the database database file when the system is newly installed, in the event of system failure When restoring, restore the backup to the current registry database, you can initialize the system "initialization", back to the state when the system was just installed (but the files in the system directory are not less). Since the registry database file is always locked by the system after booting, it needs to be operated under DOS (you can use 98 boot CD). If it is a dual system, you can directly operate to another system. Users of NTFS partition can Use “Failure Recovery Console”. At the command prompt, use the CD command to switch the current directory to the subdirectory of the %windir%Repair” and execute the following command: copy sam %windir%system32config copy system %windir%system32config copy software %windir%system32config copy default %windir%system32config copy security %windir%system32config System's life-saving straw: System Restore Windows XP's system restore function is not like Windows Me's "chicken ribs", after this failure, the system can be used to restore the system perfectly before the problem occurs. status.

Improve DOC, PDF file printing speed DOC, PDF and other files contain some or a lot of rasterized data (pictures, embedded fonts, etc.). When these files are printed, the printer driver will generate a large number of EMF files (enhanced transform files) in the system, as small as 1MB, as large as 500MB. Excessive EMF temporary files will cause a significant drop in printing efficiency. The solution is: click “ start → set → printer and fax & rdquo;, then right-click the printer you want to print select "properties", select "ld" in the "Advanced" tab of the pop-up window Go to the printer & rdquo;, click “ OK & rdquo; after the speed has increased.
