Can Windows.old be Used for Anything Useful

What is Windows.old folder? What does it contain?

When you upgrade your Windows, say for example from Windows 7 to 10, a folder called Windows.old is created as part of the upgrade. In some cases, it may also be created during a major Windows update.

Windows.old folder basically contains all files from the previous Windows installation. It is a pretty large folder that takes up many Gigabytes of space. Inside the folder, you will find sub-folders such as Windows, Users, Program Files, and Recovery. This means the folder contains all your personal files and folders, Windows installation files, system files etc. from the previous OS.

With all the space that Windows.old occupies, you may be wondering if the folder is really useful. Read on to learn more about the uses of Windows.old.

  1. To revert to the previous Windows installation

If for some reason, you are not comfortable with the new Windows upgrade, you may want to roll back to the previous version. This will put your PC back to the OS prior to the upgrade. Please note that you only have a certain number of days to rollback. So if you want to roll back, make sure you do it within that time.

But before you proceed, consider making a full backup of your system just in case anything goes wrong during the process or if Windows.old does not work as expected.

Once you have a backup in place, you can proceed with the rollback process as follows. Go to Settings on your PC and click on Update & Security. In the menu on your left, click on the Recovery option. You will find a number of options in the Recovery section like Reset This PC, Advanced Startup and Go back to Windows (version).

Select Go back to Windows (version) and Microsoft will ask you the reason for rolling back. Once you answer the question, Microsoft will provide some updates if available to see if you want to reconsider rolling back. If you are not satisfied, confirm that you want to roll back and proceed.

Microsoft will list ‘The things you need to know’; click on Next and you will be reverted to your previous installation.

Please note you will need your old Windows password to login to your system.

  1. To recover files

Normally when you upgrade Windows, your applications, settings, and data should be automatically added to your new installation. However, if the update was paused midway or there was a problem during installation, things might get messy.

In such cases, if you need to recover files or folders, you know where to find it. It will be in Windows.old folder. If Windows.old folder doesn’t contain the file you are looking for, you may want to use data recovery tools such as Remo Recover to recover files and folders.

Delete Windows.old folder

Although Windows.old folder is useful at times, you may want to delete it if you are running low on storage space. You cannot delete using the usual ‘delete’ method, instead you will have to follow a special technique explained as follows.

  1. Click on Windows + E to open File Explorer and right click on C:
  2. Click on Properties > General tab
  3. Select Disk Cleanup > Clean up system files
  4. You will be shown a list of files to delete. Select ‘Previous Windows installations’ and this will delete the Windows.old folder for you.

Precautions

After you delete Windows.old folder, all previous installation files will be gone, so make sure you are not going to need those files or even better to have a backup before you delete this folder.

How to Fix Error Code 0xc0000225 in Windows 10

In this article, let us discuss an error ‘0xc0000225’ that occurs when you boot your PC. It can be a little hard to track what’s causing the error because the error message that comes with the code isn’t very helpful. It only reads ‘an unexpected error has occurred’ or in some cases, it may read ‘A required device isn’t connected or can’t be accessed’. These messages are not very helpful, isn’t it?

But don’t worry, in this article, we explain the reasons for this error and some simple solutions to help you resolve the error.

The main reason for ‘0xc0000225’ error is when the OS cannot find the correct system files (BCD) to boot or when the system files are damaged.

Troubleshooting steps to resolve ‘0xc0000225’ error

  1. Use the Automatic Repair function

This is the simplest troubleshooting step to fix the error ‘0xc0000225’. To use the repair feature, insert a Windows installation disc and select Repair your computer on the bottom left corner.

  • Then click on Troubleshoot > Advanced Options
  • Click on Automatic Repair

This process is designed to repair startup errors in your PC. So, wait for the repair process to complete and see if you can boot the system normally.

  1. Run System File Checker

SFC, short for System File Checker is a tool that is used to fix issues with system files. To run this tool, use the same steps as explained above and enter the Advanced Options menu.

In the menu, click on Command Prompt and type the following command

‘sfc /scannow’

This command will check for corrupt or missing system files and restore them if required. Once this process completes, system files should be in good shape and you should be able to boot into your system.

  1. Rebuild BCD

If running SFC doesn’t do the trick, you may have to rebuild BCD manually. BCD stands for Boot Configuration Data and this file contains important information to boot your system. Any damage to this file may produce errors such as ‘0xc0000225’.

In order to resolve this error, you can rebuild BCD manually. To do so, enter the Advanced Options menu using the same steps as above and click on Command Prompt.

In the command prompt, type these commands and hit Enter after each of them.

‘bootrec /fixmbr’

 ‘bootrec /fixboot’

 ‘bootrec /rebuildbcd’

‘Fixmbr’ command is used to write a compatible installation into the system partition. This will resolve any MBR corruption issues. ‘Fixboot’ is used to write a new boot sector to the system’s partition. This option is useful if the boot sector is damaged. ‘Rebuildbcd’ is used to completely rebuild the BCD.

Once you perform these operations, all issues related to BCD will be fixed and this should help you resolve the error. If this doesn’t help, proceed to the next step.

  1. System Restore

System Restore is an option that is used to restore your PC to an earlier point in time. This will undo any changes you made to your computer due to which the ‘0xc0000225’ error may be produced. To use System Restore, go to the Troubleshoot menu using the steps in solution 1. Then click on System Restore and select a restore point, ideally, this point should be prior to when you suspect the system changes may have occurred.

If you have trouble with System Restore, refer system restore not working Windows 10.

  1. Reinstall Windows

If none of the above methods work, you may have to reinstall Windows entirely. To do this, again use the installation disc and click on Repair your computer. In the Troubleshoot menu, click on Reset This PC. This will reinstall Windows and also allow you to save your files in the process.

In cases when you have lost files after Windows installation and looking for recovery options, Remo Recover is a great choice. It provides recovery solutions for various data loss situations such as Windows reinstallation, factory reset or due to a Windows upgrade. Download a trial version today!

What is Target Disk Mode? How and When to Use it on Your Mac

Target disk mode is a type of boot mode in Mac that is used to transfer large files such as disk images, important backups etc. in a quick and efficient manner. This mode is also useful when you want to troubleshoot or access your Mac when it doesn’t boot.

How to use Target Disk Mode?

You will need 2 Mac systems and a FireWire cable to use Target Disk Mode. The Mac systems you plan to use for TDM needs to have a FireWire or Thunderbolt port.

One Mac acts as a Target, which as the name suggests is the system you want to access. It could be the non-booting Mac or the Mac with issues. The other Mac is the Host; this is the system that will be used to access the target, Mac.

Once you have both Mac’s set up, follow the steps below to use Target Disk Mode.

  1. Connect the two Mac’s

Connect the two Mac’s using FireWire or Thunderbolt cables. Also, make sure your Mac’s are plugged in to avoid running out of battery during the process.

  1. Start Target Disk Mode on target Mac

This can be done using 2 methods described as follows.

  • Restart your Mac and press the ‘T’ key until you see a FireWire icon on the screen. T
  • If your target Mac is turned ON, go to System Preferences > Startup Disk and select Target Disk Mode.

Once you have Target Mode turned ON, you are all set to transfer files.

  1. Transfer files

Your host Mac should now be able to detect the target, Mac. Now you can use this Mac as you would like any other external storage media. Open Finder to transfer any files you need and once that’s done, click on Eject to safely remove the connected Mac.

Why use Target Disk Mode?

Now that we know the basics of Target Disk Mode, let us understand when you can use this mode.

  • To transfer files

Instead of using a USB flash drive or external hard drive as an intermediary between 2 Mac’s for transferring files, you can directly use a Mac to transfer files to another Mac. This is particularly helpful to transfer large files such as backups, disk images etc.

  • Troubleshoot or access Mac that won’t boot

This is probably the most useful application of the Target Disk Mode. Sometimes you may face problems with booting your Mac (the common problem when you upgrade Mac). In such cases, you can use Target Disk Mode and access it through another Mac.

Once connected, you can perform troubleshooting on the target Mac or copy important files from the problematic Mac. However, if you’re still having trouble booting your Mac after using TDM, refer Mac wont boot after Sierra update. This link will provide you with some tips on recovering important files after OS upgrade.

Conclusion

While Target Disk Mode can be extremely useful when your Mac doesn’t boot or for file transfers, there are some drawbacks. For instance, you can’t use this mode if the target Mac’s drive is damaged or there are other hardware problems. But this is definitely a good option to consider when your Mac just has booting issues or screen trouble etc.

How to Clean up Mac from Virus or Malware Infection

 

You may have heard that Mac systems don’t get attacked by viruses. But that is just incorrect information. Sure, your Mac’s do have a built-in protection and better security, but it is important to understand that they are not exempt from virus or malware.

How to know if your Mac is infected?

Listed below are some common symptoms if your Mac has been infected by a virus.

Note: These symptoms don’t always indicate virus infection but it is just a possibility.

  • Your Mac is experiencing an unusual slowdown and nothing you do to improve the speed helps
  • Malware attacks your system mostly in the form of browser extensions. These plugins normally claim to help you make search easier, but they are just malware
  • You find way too many advertisements in all the web pages you visit

How to clean your Mac from the virus?

Solution 1: Remove browser extensions

Follow the steps below to remove browser extensions from your system.

  1. Open Chrome application and click on the three dots in the top right corner
  2. Choose More Tools > Extensions
  3. Carefully go through all the extensions in the list and remove the ones you are not familiar with.

Solution 2: Remove troublesome applications

Certain applications may present to you in the form of security software or a cleaner. But when you go ahead and download it, it may turn out to be a virus or malware. Luckily you can uninstall these apps and get rid of the malware.

To uninstall these apps, go to the Applications folder, click on the app and drag it to the Trash. In some cases, even if you uninstall the app, there may be certain residue files related to the app still on your computer.

Go to the ~/Library folder and check the Application support folder for files related to the app and delete them. But before you delete, confirm if they are the right files as deleting wrong files may cause major problems.

Solution 3: Scan using an anti-virus program

Although the above steps help in removing certain kinds of malware or virus, it is not always as effective as using an antivirus to remove viruses.

There are many antivirus programs available in the market, but it is important that you choose a reliable one. But beware of free ones, as they may themselves be viruses in the form of antivirus.

It is a good idea to invest in a good anti-virus program even though it sets you back a few dollars. You will save yourself a great deal of time, money and avoid painful data loss disasters.

Solution 4: Restore from Time Machine backup

What if none of the above methods help you remove the virus from your system? The best solution is to use Time Machine to restore your Mac to a time when things were normal.

To restore using Time Machine, connect your Time Machine drive and restart your Mac by pressing Command + R keys. Then select Restore from Time Machine backup and choose an appropriate backup point. That’s it, your Mac will be restored and all programs and data installed after that backup point will be erased, effectively eliminating the virus. If you find some important files are deleted during the process, you can use tools such as Remo Recover to recover deleted Time Machine files.

If you don’t have a Time Machine set up, the last option is for you to reinstall macOS. But be sure to back up your entire system before you attempt this step.

Resolved – Invalid JPEG Marker Type is Found

JPEG’s are one of the most commonly used types of photo formats. They are preferred due to the less storage space they occupy and a fairly decent image quality. Although it is a reliable and commonly used format, you may encounter problems with it occasionally.

Errors such as ‘Could not complete your request because it is not a valid Photoshop document’, ‘This is not a valid PDF’, and ‘Could not complete your request because an unknown or invalid JPEG marker is found’ are common.

In this article, we discuss an error ‘Invalid JPEG marker type is found’ and some effective solutions to resolve the error.

Solution 1: Make sure the file extension and the exact file type matches

There is a possibility that there is a mismatch between the actual file type and the extension you type in the filename as a result of which an error may be produced.

  1. Go to File Explorer and click on Organize > Layout > Menu Bar
  2. Click on Tools > Folder Options > View
  3. Clear the checkbox next to ‘Hide extensions for known file types and save changes’

Solution 2: Double check the file extension

Sometimes, you may manually type a file extension to a file that already has an extension. In such cases, turn ON file extensions as explained in Solution 1 and check the name of your images in Explorer.

If you find a file like test.jpg.pdf, this is a problem. In such cases, remove the last extension ‘.pdf’ and save the file.

Solution 3: Save the problematic JPEG using a different photo app

You can make use of other photo tools such as Photos (on Windows) etc. to resolve the issue. To do this, open the problematic JPEG using Photos, and save the file as a JPEG image. Once the file is saved, try to open it again using Photoshop. This may solve the problem.

Solution 4: Run hardware trouble-shooter

Issues with your external hard drive, USB or other hardware on your system may produce errors such as ‘Invalid JPEG marker type’. To check for problems with your hardware, run a hardware trouble-shooter.

  1. Click on Start button > Control Panel (Or press Windows + X and select Control Panel)
  2. In Control Panel, click on Hardware and Sound > Configure a device
  3. In the hardware troubleshooter window that opens, click on Next to start troubleshooting

If none of the solutions work, there is a possibility that your JPEG file is corrupt as a result of which you may be facing issues. To repair corruption in JPEG files, you can use third-party JPEG repair tools such as Stellar Phoenix, VG JPEG Repair, RS File Repair etc.
