've been called urgently today by miss Jenia Pencheva who is the president of Christian Air Ticket Agency GoodFaithAir, her personal computer caused her quite a lot of headache, I've previously fixed it once and she was happy with that thus when she experienced problems she give me a call for remote IT support :).
She explahed her PC was unable to boot normally and in order to have some Windows she ended in Safe-Mode with Networking state. This problems caused her business losses as during PC in Safe mode the screen resolution even though with networking and she couldn't use the flight ticket ordering systems to purchase her customers new tickets. I've earlier installed TeamViewr on her PC so after Logging on the PC, I've immediately realized the Hard Disk was almost full (less than 1Giga free on C: Drive – where Windows install lived).
After a thorough investigation on which directory is occupying most of disk space (110GB) with a nice program called SpaceSniffer which is perfect for finding lost space on your hard disks, I've found System for ticket reservation Amadeus CRS (Computer Reservation System) was causing the disk full-full troubles.
I've found troubling directory was:
C:UsersgoodfaithairAppDataLocalMicrosoftWindowsTemporary Internet FilesContent.IE5
To solve it I first tried to Clean up Internet Explorer Cache (I've checked ticks Temporary Internet files, Cookies, History, Download History, Form Data, InPrivate Filtering Data).
Then I used Microsoft Windows embedded clean manager (cleanmgr.exe) to run disk clean up, however Desk Clean Up managed to clear up only about 1Giga and on the computer HDD which is 150Gb still on Windows installation drive C: only 1.5GB were free.
Besides that the system was having a second trouble as there were some failed updates (Computer was not shutdown properly but shutdown during Windows Update) and this was making the machine to enter Safe-Mode, I was fixing the system over TeamViewer session so after restart I had no way to see if Windows boots Normal or Safe-Mode after restart, thus to find out whether Windows was in Safe-Mode after another restart I've used below PowerShell one-liner script:
PS C:> gwmi win32_computersystem | select BootupState
Fail-safe with network boot
Note that possible return results from above command are:
Fail-safe with network boot
I've been struggling for a while (had to restart it multiple times) until finally I managed to make it boot in normal mode. Because PC was failing to apply some Windows Update, thus dropping by in Safe-Mode each time. To solve that I had to go and Delete two of the last Applied updates (KB2979xxxx files).
Control Panel -> Program and Features -> View Installed Updates
I've restarted and since I couldn't see the screen on Windows boot-time, I don't know what really happened but the PC booted again in Safe-Mode, and I thought the classical way to fix PC booting in Safe-Mode with SFC command will help:
C:> sfc /scannow
but for my surprise this helped not as the system continuously booted in Safe-Mode, to fix the Windows PC always booting to Safe-Mode, I had to change it running msconfig and unticking Safe Mode field
Then I tried to delete Temporary Internet Files with below DEL cmd line
C:> del "C:UsersMyNameAppDataLocalMicrosoftWindowsTemporary Internet Files*.*"
To finally succeeding in manually delete huge Temporary Internet FilesContent.IE5 folder, I had to use good old RD (Remove Directory) command.
C:> RD "C:UsersusernameAppDataLocalMicrosoftWindowsTemporary Internet FilesContent.IE5" /Q /S
I used also following dels command to delete other common locations where Windows stores temporary files
For those who like to batch DeletingTemporary Internet Files and most common Temp locations to be cleaned on Windows boot I recommend you schedule a start of (clean-temporary-internet-files-content_ie5_folder.bat) on every PC boot.
To Clean-up other common Temporary file locations that could take you disk space the command line way run in new Administarator privileged command prompt:
del /F /S /Q "%systemroot%temp*.*"
del /F /S /Q "%systemroot%Prefetch*.*"
del /F /S /Q "C:Documents and SettingsDefault UserLocal SettingsTemporary Internet FilesContent.IE5*.*"
del /F /S /Q "C:Documents and SettingsDefault UserLocal SettingsTemp*.*"
del /F /S /Q "C:Documents and SettingsDefault UserLocal SettingsHistory*.*"
del /F /S /Q "C:Documents and Settings%UserName%Local SettingsTemporary Internet FilesContent.IE5*.*"
del /F /S /Q "C:Documents and Settings%UserName%Local SettingsTemp*.*"
del /F /S /Q "C:Documents and Settings%UserName%Local SettingsHistory*.*"
del /F /S /Q "C:Documents and Settings%UserName%Local SettingsApplication DataTemp*.*"
del /F /S /Q "C:Documents and Settings%UserName%Local SettingsApplication DataTemporary Internet FilesContent.IE5
del /F /S /Q "C:AppDataLocalMicrosoftWindowsHistory*. *"
del /F /S /Q "C:AppDataLocalMicrosoftWindowsTemporary Internet FilesContent.IE5*.*"
del /F /S /Q "C:AppDataLocalMicrosoftWindowsTemporary Internet FilesLowContent.IE5*.*"
del /F /S /Q "C:AppDataLocalMicrosoftWindowsTemporary Internet FilesTemporary Internet FilesContent.IE5*.*"
del /F /S /Q "C:AppDataLocalMicrosoftWindowsTemporary Internet FilesTemporary Internet FilesLowContent.IE5*.*"
del /F /S /Q "C:Users%UserName%AppDataLocalTemp*.*"
del /F /S /Q "C:Temp*.*"
del /F /S /Q "C:Users%UserName%AppDataLocalMicrosoftW indo wsTemporary Internet FilesLowContent.IE5*.*
del /F /S /Q "C:Users%UserName%AppDataLocalMicrosoftW indo wsHistory*.*
::Rem: No need to duplicate the following section for each registered User
del /F /S /Q "%homepath%Cookies*.*"
del /F /S /Q "%homepath%recent*.*"
del /F /S /Q "%homepath%Local Settingscookies*.*"
del /F /S /Q "%homepath%Local SettingsHistory*.*"
del /F /S /Q "%homepath%Local SettingsTemp*.*"
del /F /S /Q "%homepath%Local SettingsTemporary Internet FilesContent.IE5*.*"
Note that in some cases running above commands might left you loose some sensitive data and in case where Internet is slow cleaning temporary files, might have impact on surfing also you will loose your history so be sure you know what you're doing as you might loose sensitive data.
Finally I've run MalwareBytes to clean up the PC slowness caused by Spyware and other left Malware I've run MalwareBytes, RogueKiller, AdwCleaner, RKill, TDSSKiller in order and I found and removed few Malwares as well.
That's all, hope you learned something new. Enjoy!
