Windows Repair Disc - Rollback a driver from Windows Command Prompt? (Windows in evil Update reboot loop)


I think I found the problem to my Windows 7 Reboot Loop when it goes to configure from a Windows Update (it stops at 32%). Even when I choose Safe Mode which says it is reverting the Windows Updates.


I'm not 100% sure but it could be my UPEK Fingerprint driver. There was a recent release of an update for it, and Windows Repair Disc did a scan and, though it couldn't fix the issue, the results stated that a driver error was not letting windows startup.


So, once I'm in the Windows (R) aka Windows Repair I have the option to load up Command Prompt. I can then access my Windows Drive which for some reason got assigned to D: instead of C: ... my question is:


Normally if I want to remove a driver I go to Start>Control Panel>System, click on the device and remove it (the driver get's removed). What is the equivalency of this in the Command Prompt?



Answer



Driver Information is stored in the registry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services


You could use the reg command:


http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/reg.mspx?mfr=true


Example the VGA Driver information is in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\vga


But you will have to know the folder name of the driver. Once you find the folder you would have to change the REG_DWORD named "Start" to 4.


Start=4 is disabled Start=2 is Automatic Start=3 is Manual Start=0 is Boot Start=1 is System

keyboard - Is there any utility/method to change Windows key bindings to type rare chars to currently empty bindings?

I'm currently typing this post with my windows XP machine and (Spanish) keyboard, and I'd like to add some extra symbols to my text. I could open the "char map" windows utility, look for the desired symbols, and paste them. But I'd like something quickier. For example, when I'm using my OSX Mac at work, I can easily add a ©, ™, ® or similar symbols, just pressing some weird ALT-GR + G / H / J, key combinations. In my (Spanish) keyboard mapping, these combinations are empty, as they don't produce any char at all, which, on the other hand, is perfectly normal and desirable. So, I thought: Why couldn't I add some extra key mappings on top of my currently empty ALT-GR + G/J/H Keys in my Spanish keyboard, and thus, being able to quickly type these special symbols? So that's my question: Is there any utility/method to achieve that effect under windows? (My version is XP). I've even googled this for some time but no luck. I've been a long term Hot...

virtualization - How to select paravirtualization interface in VirtualBox?

Given a windows 8 host system (Intel Core i5) and a Linux Fedora host, I would like to determine the optimal setting for the paravirtual interface. Options are none Default Legacy minimal Hyper-V KVM This page suggest the selection is only based on the guest system: The biggest change in VirtualBox 5.0 is the introduction of paravirtualization support, bringing higher performance and time-keeping accuracy to supported guest operating systems (Hyper-V on Windows and KVM on Linux). Is that correct? Answer The VirtualBox Manual , in the section titled Paravirtualization providers explains very clearly when each should be used (emphasis added): Minimal: Announces the presence of a virtualized environment. Additionally, reports the TSC and APIC frequency to the guest operating system. This provider is mandatory for running any Mac OS X guests. KVM: Presents a Linux KVM hypervisor interface which is recognized by Linux kernels starting with version 2.6.25. VirtualBox's implementati...

Desktop reboots itself on sleep or hibernate

I have been using an ASUS M2NPV-VM motherboard for main home desktop workstation, operating Windows Vista x64. This computer has right from day one not been able to enter hibernate or standby; after Windows performs its final actions and brings the machine down, it would automatically revive itself for a reboot. Updating to the second latest BIOS (1201)has not helped (the latest BIOS revision would induce video refresh problems rendering it unusable). I have been reading related discussions on incidents similar to mine to no avail of a true workable solution. They appear to be more speculative guesses rather than actual knowledge on the inner workings of motherboard hardware. Does anybody have any electronic engineering experience on PC energy-saving standards to provide a more informed opinion how to go about getting this to work? More stories: this motherboard could not even reboot properly the first thing i used it. It was due to refresh rate of the onboard GPU, which had no influe...

Excel 2010: if( , , "") not treated the same as blank for pivot table group by date

I'm trying to group by date in an Excel 2010 pivot table. The column with dates (i.e., the one want to group by), should be the latest date of 2 other columns if neither is null, or blank. i.e., with a formula like: =IF(AND(A4 "", B4 ""), MAX(A4,B4), "") Normally, this "" in the IF() formula acts the same as an empty cell. In this case, it is preventing me from grouping by date in the Pivot Table. If I filter the date column by (Blanks) , then clear the contents of all those cells, then the pivot table does group by date ok. i.e., "" is not being treated the same as an empty cell.
