Enable System Protection on Local Disk (C:) with CMD

[Kaktussoft]

When i use CMD (logged in as a user) it says acces denied. I don't know how else to acces cmd...

Can't you run cmd at all? Or do you get "access denied" if deleting *.mybak files?

run cmd by doing http://www.sevenforums.com/tutorials/783-elevated-command-prompt.html
This runs cmd with admistrator right. Now you can delete the mybak files

Run windows update and search for updates. Does it offer the updates again?

It offers 12 updates + another 4 (opional)

Those are most likely the same ones you installed on 9 jan(?) Nothing in windows update history refers to 9-jan (order list by date), so win7 thinks they weren't installed? If so... install only internet explorer, ms office and .NET updates. Reboot afterwards. System still boots fine afterwards?

 

[Kaktussoft]

Please respond.
Install all windows updates (not the optional updates). System boots fine afterwards. In case of problems I know how to uninstall them from recovery environment. Even better is install 2 updates each time and write down which one you did. So you know which ones are causing trouble.



Optional updates are optional... you can decide later if you want them.

I have exactly the same problem, but on my desktop pc...
Weird thing is that in win explorer my OS (win 7 64) is on C: but in DOS it's on J: (I do have lots of partitions)
I'm gonna follow what's been discussed here, and will post my results.
Thanks in advance.

What now ?

 

[PaulVdB]

When I boot now, I get
STOP c000021a fatal system error
verification of known DLL failed

after few seconds MB starts to beep : indicating a (too) hot processor
never was too hot while doing all previous restore/repair actions...

How to Enable System Protection in command prompt.

Rstrui.exe /offline:c:\windows=active

 

[Kaktussoft]

Rstrui.exe /offline:c:\windows=active

Rstrui.exe /offline:c:\windows is the command to perform a system restore offline.

Genius Solution!!!

Same windows update issue - Laptop disconnected from power while installing update and then windows starts to blue screens on boot.

After hours of trying different options and searching online. I abandoned the laptop for a few days to later copy data off and restore to factory, I just thought I should search online again before factory reset and found this page. The Regback solution worked!!! Genius!!!

Thanks Kaktussoft!!!

I am having a similar problem and some steps worked. However, after I enter cd \Windows\System32\config it says the system cannot find the path specified.

What problems do you have? I mean why are you inspecting that folder?

DIR  C:\Windows\System32\config 
dir  D:\Windows\System32\config

What gives the output you want?

 

[angelzrei]

Whenever I open my pc it says that my pc did not start properly; so, I restart it but I end up with a black screen. I tried most of the options but it did not work; so, I wanted to try doing a system restore.However, I can't because it says I must enable system protection on this drive. I read Green18's problem and it sounds similar to mine so I was trying to do the steps that you have posted; but, I am having a problem with the step on #28.

I am unsure what the codes do. I was following what was posted.

So I had the same problem with my computer, restart error, no image to restore too and the root error giving the same exact message.

Did the

ren default default.bak
ren sam sam.bak
ren security security.bak
ren software software.bak
ren system system.bak
copy RegBack\*.*

Rebooted, and it worked. However do not have any access to my keyboard or keypad since.

Did I accidentally delete some drivers that are needed somehow?
Tried also plugging in a mouse but didn't work either.

Any help would be appreciated

Just before the RegBack trick the mouse and keyboard were still working fine in win7?
keyboard, mlouse, keypad.... are all usb I assume?

Can't you communicate with computer whatsoever? I think usb drivers are damaged (?) What happens if you attach a usb stick or external drive? Do you see that new hardware is attached?

 

[Calpow]

The external mouse is USB however the keyboard and keypad are standard. I just plugged in the external mouse to see if it would work. The standard keyboard and trackpad were working fine before the RegBack. Did some searching and it seems like my model UX31E has keyboard and trackpad problems and a standard fix is taking off the back and tightening the lose component.

Kinda perplexed by this

Also forgot to add only communication I can do with the computer is turn on power then it goes to login screen. However when I force shutdown and it gives options to start in safe mode or regular I hit enter and it works? Weird, then I get to the sign in screen and can't use either. When USB is plugged in it doesn't show any thing

So usb keyboard is still work in boot menu http://www.sevenforums.com/tutorials/666-advanced-boot-options.html , is that correct?

"When USB is plugged in it doesn't show any thing"... what would you expect to see?

 

[Calpow]

Oh no, the keyboard isn't USB it's just the standard laptop keys. The only thing I had plugged in was the mouse, however it didn't respond to that either. When in the startup screen for boot options safe mode w/ networking etc I can select start windows regularly with the enter key. Just weird it doesn't work once it boots all the way

safe mode works as expected (keyboard and mouse works)?
In normal mode: Boot to normal mode. When completely booted attach a external disk or usb stick. any popup like "new disk detected"?

So you did something like http://www.sevenforums.com/tutorials/139576-startup-repair-infinite-loop-recovery.html ?
Folder C:\windows\system32\config has these files? what is rhe date time of the files, and all are larger then 200000 bytes?

• DEFAULT
• SAM
• SECURITY
• SOFTWARE
• SYSTEM

The DEFAULT, SAM and SECURITY files should each be about 262,000 bytes in size.
The SOFTWARE file should be about 26,000,000 bytes.
The SYSTEM file should be about 9,900,000 bytes.
The file sizes presented here are approximate estimations, and may vary depending on your system. If any one of them are 0 bytes, then you should stop what you're doing now and seek an alternative method of recovering your system, because Windows cannot function with a 0-byte size registry hive.
