Computer Repair Windows update in Longmont, Boulder, CO

Our Longmont Computer Physicians, LLC office computer had an interesting issue recently I thought I would share:

After an automatic installing of windows 10 update for Valentine’s Day Feb 14, 2018 (KB4074588) my USB keyboard on my desktop computer would no longer work. I tried 3 different USB keyboards  – none worked.  So I went into device manager to uninstall, reinstall, and update the keyboard drivers.  That did not work. So then I uninstalled the windows update.  This fixed the problem, but the update would try to install again the next time I reboot.   So I set the windows update to never install hardware drivers during the update in (system properties) I would need to choose what driver update I want manually from now on.

A thread of execution, or simply a “thread,” is one series of
instructions sent to the CPU. Hyper-threading is a technology
developed to help make better use of spare processing cycles.
Hyper-threaded processors have a duplicate set of registers,
small spaces of high-speed memory storage used to hold the
data that is currently needed to execute a thread. When a CPU
core is delayed, waiting for data to be retrieved from another
place in memory, it can use these duplicate registers to spend
the spare computation cycles executing a different thread. The
second set of registers will be pre-loaded with the data needed
to execute the second thread, so the CPU core can begin work
immediately

used in devices that require the fastest possible data access
without requiring a high capacity. Some examples are CPU
caches and buses, hard drive and router buffers and printers.
DRAM
Dynamic RAM stores data using a paired transistor and
capacitor for each bit of data. Capacitors constantly leak
electricity, which requires the memory controller to refresh the
DRAM several times a second to maintain the data.

types of hard disk, based on the the intefaces they used we can
classify them as IDE, SATA, SCSI etc…
95. What is SATA?
Serial ATA (SATA or Serial Advanced Technology Attachment.
is a computer bus interface for connecting host bus adapters to
mass storage devices such as hard disk drives and optical
drives. Serial ATA was designed to replace the older parallel
ATA (PATA. standard (often called by the old name IDE),
offering several advantages over the older interface: reduced
cable size and cost (7 conductors instead of 40), native hot

requires its own power connector. It is still an excellent choice
for external disk storage.
98. What is SCSI? Is the SCSI Hard Disk is needed for a home
purpose?
SCSI is Small Computer System Interface , is a type of
interface used for computer components such as hard drives,
optical drives, scanners and tape drives. SCSI is a faster, more
robust technology than IDE amd SATA, and has traditionally
been utilized in servers. Aside from speed, another great
advantage over IDE and SATA is that the SCSI card can
connect 15 or more devices in a daisy chain. The controller
assigns each device its own SCSI ID, allowing for great
flexibility towards expanding any system. It is more costly. It is
not needed for a home purpose.
99. Is there is USB HDD? If yes what is the speed?
Yes. If your HDD is based on USB 3.0 it can offer a maximum
transmission speed of up to 5 Gbit/s (640 MB/s), which is over

100. What is IEEE 1394 Interface?
The IEEE 1394 interface is a serial bus interface standard for
high-speed communications. The interface is also known by
the brand names of FireWire (Apple), i.LINK (Sony), and Lynx
(Texas Instruments). IEEE 1394 replaced parallel SCSI in
many applications, because of lower implementation costs and
a simplified, more adaptable cabling system. The original
release of IEEE 1394-1995 specified what is now known as
FireWire 400. It can transfer data between devices at 100,
200, or 400 Mbit/s.
