I have an Amazon Web Service EC2 virtual server large type. Now I want to downgrade it to small type. I want to keep the hard disk information but just download the configure of the server. The main reason is to save few bucks. How can I do this?
I think I should:
stop the current instance.
detach the volume from the current instance.
terminate the instance.
recreate a new small-type instance from scratch.
attach the volume to the small-type instance.
I am not sure whether this is the correct way to do the downgrade or they have some formal way to do it. I tried to look up from the doc but couldn't find anything useful. I think someone here must be able to help me. Thank you very much.
I don't know how it worked back then in December 2010. But now it's very simple, maybe Amazon simplified it recently.
Steps
Stop the instance
Click the Check box next to the instance
Click Actions button
Choose "Change Instance Type"
That's It!
I think the best way is:
Snapshot the volumes from the current instance.
Create the new small type instance
Use the snapshot(s) to create a replica of your existing volumes.
Attach the new volume(s) created to small instance.
Test it and switch ElasticIP to the new instance if everything is working ok.
Stop the instance
Click the Check box next to the instance
Click Actions button and Choose "Change Instance Type"
Start the Instance.
That's It

Please take a look at these two threads :
how-to-clear-eventlog-with-powershell-or-wevtutil
delete-old-entries-of-the-event-log-with-powershell
Some days ago some body stole my password of wi-fi and connected to it.
After connect he hacked my windows 7 pc through home network.
Something is so strange for me.
After hack he deleted all wi-fi logs for two moths ago.
I never do that because i even did n't know there is a wi-fi log in my pc.
Check here for wi-fi logs & it's location
How is that possible because people say you can't delete event logs in period of time by command.
Just tell me how could he do that?
Does he have GUI access to my pc?
I am so confused because of this action?
Almost anything is possible if you have administrator rights on a machine
There is no built-in function to delete only certain logs, but one example way to do this is simply export all logs except the ones you want, then replace the original log file with your filtered log. The built-in wevtutil can do this pretty easily:
# filter out events on 2022-05-11
# export to test.evtx
wevtutil epl Application test.evtx "/q:*[System[TimeCreated[#SystemTime<='2022-05-13T23:00:00.000Z' and #SystemTime>='2022-05-10T04:00:00.999Z']]]"
That aside - Windows 7 stopped receiving security patches in January of 2020, so consider upgrading your operating system for the future.
If you think that person could still have access to your computer, then your best action is to is to wipe it and start over. A computer repair service should be able to help you do this and keep your important files.

I want to deploy my existing Laravel application in the Digital Ocean and this is my first time to go live. I'm choosing droplets shared CPU $5/month my questions are.
Is $5/month is exactly the amount that I will pay for the monthly bill?. If my application is online/accessible forever do I still get to pay $5/month?.
As stated above that I'm using the Laravel framework, can I ssh in the server and install dependencies without a problem?, also can I change the PHP version in the server?.
Please help me this is my first time and I have no idea what to choose if shared or dedicated CPU'S.
Note: My Laravel application is only for my personal use.
Here is my screenshots.
Thank you in advance.
Yes, that is the price that you will pay each month unless you turn on features like automatic backup and etc. which add up a couple of extra $.
You can, however, get billed more if you go over the droplets outbound data transfer. Check it here. But since you said it's only for your personal use, no worries there.
Yes, you can ssh into your server and install whatever you need on it (composer, database, PHP libs).
For every package, you are still billed hourly up to the end of the month which roughly equates to the price on that screenshot. That means that you can play around with your droplet, see how it works, and if you change your mind, you can always delete it, and only be billed for the number of hours that you used it.

A friend of mine factory reset her computer on Windows 10, and lost an important document, so I'm wondering if there is a way for her to get it back, any help is useful.
I realize that a factory reset sets the computer back to it's original state of when it was first purchased, but I'm just curious if there are any free or cheap options available, besides going to a recover specialist.
Any advice would be nice - thanks!
Download the free version of Piriform Recuva. It is something I have used before for basic file recovery, and I don't know of a simpler GUI tool for Windows. Simply follow the instructions of this tutorial, or search for a simple video tutorial on YouTube if that is insufficient.
To maximize your chances of recovery reduce the amount of writes to the drive- setting it to read-only for example. Avoiding doing anything else while you attempt to recover the files is critical, newer files may silently destroy whatever is left of the older data. If at all possible you should attempt to boot from a drive or disk that doesn't contain the erased data, but if that is not possible/not something you know how to do then you may still be able to recover the data by booting the computer normally.

I bought a notebook recently and will give it to someone else on their birthday. That person, however, is not good with computers yet and so I wanted to create a full-screen app that would introduce them to the computer. The app works perfect, the thing is just that I need it to start when logging in to their account (just once, too, obviously).
I know there's a folder in which you can place executables that then will be executed at login, however, that is simply not fast enough.
When the PC boots and the automatic login is done, the desktop is shown for about 3 minutes until the full-screen app finally opens (the laptop is not really a powerhouse tbh though).
How can I make it open the app faster? Or could I maybe make Windows not start explorer.exe until my app is open? Thanks.
(OS is Windows 10)
There are multiple ways to do this.
One is by using registry. You can add necessary registry entry under:
HKEY_CURENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
This would run your application right after the user logs in.
Another one would be to create a new task through Task Scheduler:
When creating tasks you have lots of option to control when it starts. You can start it at log-on of specific user, you can start it even before user log-on so you can explain the user of how to properly log-on to the computer, etc.
You can also control if this task is executed once or every time.
I personally would go for second option as it does not require any manual registry editing and therefore it can be setup even on non-administrative account.
You can change the registry to accomplish this.
You can modify the "Shell" key at
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
to the full path of your program.
This should replace explorer.exe and your program should start "explorer.exe" and set this registry's value back to "explorer.exe" after it's started.

I have deleted user by "Delete user folder (safe)" mode in Mac OS X V 10.7.5. Please, don't ask me why, but now I need it.
I am googling it, but nothing usefull. I found some folders with name like "6 17-11-10-062.0", "6 17-11-10-062.0", "6 17-31-31-784.0" and "6.0" in my trash. What is it?
How can I recover user data? What program can help me? Sorry for my English. Thaks :)
If you used the "Delete the home folder" with "Erase home folder securely" option, there's no way to recover it. If you had not chosen the "Erase ... securely" option (and not done much else with the computer after deleting the account), you might've been able to use data recovery software to find & recover at least some of the files. But what the "... securely" option does is to overwrite the deleted files to make sure they're really really gone and unrecoverable. That's what they mean by secure deletion.
There's a slight possibility that you might be able to use data recovery software to find traces of files that were deleted normally (insecurely) from the account before the account itself was deleted. But I wouldn't expect to find much, and what you would find would be (by definition) old versions and other things you considered unimportant.
If you are interested in trying to do data recovery, stop using the computer immediately. Shut it down and use some other computer to research your options (this superuser question is a good place to start). The more you use the computer, the more of the old files will be unrecoverable because the space they were stored in is continuously getting reused for new files, and once it's reused, whatever was there before is gone.
I don't know what the folders you found in your trash are, but I'm pretty sure they're nothing to do with the deleted account. Sorry, but unless you have a backup, I think you're not going to be able to get much of anything.
