Double-click a workbook and Excel opens your file plus an empty gray window? Something loads at startup. Check File, Info in the empty window, then Personal.xlsb in XLSTART and your COM add-ins.
Excel cells showing =A1+B1 instead of the answer? A whole sheet means Show Formulas is on; one cell means Text format or a stray apostrophe. Set General, then press F2 and Enter.
Pasted text spreading across columns in Excel? It reuses the delimiter from your last Text to Columns split. Run the wizard once with only Tab ticked, close every Excel window, or press F2 before pasting.
W moves the cursor up and the arrows type letters? Gaming keyboards swap WASD and the arrows with Fn and W. Press it again, try the other order, check the keyboard app, then rule out a Windows remap.
Touch input going to your main screen instead of the touch monitor? Windows could not pair them. Run Setup in Tablet PC Settings, slide your finger if the tap misses, and redo it when it drifts.
Windows says We can’t set up mobile hotspot? Read the reason after the message, ignore Hosted network supported No, enable the Wi-Fi Direct adapters, and change the name, password and band.
Media Creation Tool says it cannot find a USB flash drive? Use a stick of 8 GB that Windows lists as Removable, try a USB 2.0 port, or copy the Windows ISO to a FAT32 stick yourself.
The Run as administrator box is gray in a shortcut’s Advanced Properties? Put the program in front of the script in Target, use the Compatibility tab, or make a new shortcut from the .exe.
Your USB stick shows No Media and 0 bytes in Disk Management? The controller answers but the memory does not. Try another PC, uninstall the disk in Device Manager, then plan for a replacement.
Registry Editor says Error while deleting key? A hidden null character in the key name is the cause Microsoft names. Run RegDelNull, take ownership of the key, or remove the driver behind it.
